Choyak,

Two comments:
1. When mine went out it wasn't the TC it was the Unitrol/Robert Shaw gas valve that did the trick. The pilot relit twice after the initial failure then it wouldn't light again. New TC did nothing, pilot wouldn't light, died every time I released the button. New gas valve (along with the TC) got it working, lint filter...err I mean flame arrestor was immaculate. If this happens a few more times I'll open a few discrete ports in it with a Dremel. I don't pour gasoline next to water heaters or furnaces or in my basement at all, so I'm not exactly worried. Lived with plenty of water heaters without FVIR, nary a problem with combustion on any of them.
2. I was also planning to go the GE/Rheem route in the event that I quit getting warranty parts...until I saw the exact same Unitrol Robert Shaw gas valve on the one in Home Depot--(okay it had red knobs instead of black.) Since this part has been the problem on my Whirlpool it doesn't give me any confidence to see the same #$@!^& thing on the GE. The intake looks better on the GE, but it was the control (which isn't exposed to the combustion heat) that failed on the Whirlpool.

Good luck with yours, we all need it... In my defense, I didn't buy this thing, the previous home owner did.

OMGOMGOMGOMGOMG I do not know if the DENIZEN OF LUCK has arrived yet, or if it will FUBARIZE again, but what I did was BEYOND BELIEF but I had only enough TIEM to watch the water get pseudo hot. THE PILOT STAYED ON for one time so far it did not dump, the water got hot. I DECREASED THE GAS FLOW THROUGH THE MAIN VALVE!!!!!!!!!! OMGOMGOMG

I also (WITH GAS ON FULL) WATCHED THE MAIN FLAME IGNITE, and FLAMES SHOOT THROUGH the alleged 'flame arrestor' (you needed to brush it)

one more time, I WATCHED FLAMES SHOOT THROUGH THE GRILL OUT OF THE BOTTOM ONTO THE WOODEN BASE. So I put an 8" square aluminum plate underneath there.

I put the gas valve close to being OFF, the main flame was about 50% of when gas on. I am aware it will require more time for the water to get hot, but AFAIK that will not be a problem until 3 billion people simultaneously take showers. It's 40 gallon.



I just went outside and stared at the GE and yupp same damn unitrol crap, but the 3 lines go STRAIGHT DOWN into the combustion chamber, not all curlicue like the WHORFOOL!!

yes, I inherited this POS just like you did.

and yes, I also inherited this POS from the previous homeowner. My 6 year old or so GE is still flawless so far


Well, I don't know if I drained enough water, like maybe 2 gallons, but water was pissing out of the pressure relief pipe and it arbidumped again. Isn't there a shutoff valve on the inlet??? I am conjecturing that the gass valve refused to shut off when it got hot. I have another new gas valve that I guess I will have to replace tomorrow 4 miles drive again not happy with exxon stock. I just set it to off and the tenants have one tank of hot water for a few showers. I guess I will screw with it tomorrow it is 4 miles away from me so no one will get to retire with their exxon stock. I also am aware that when you remove the gas valve, the water will all gloog out unless you MT the tank.

As for the flames shooting through, I should camcorder it and start a PROPER class action suit, like getting the dictators of these DUMPANIES in JAIL

I will post the pic of my car rear window with WIRPOOL WATER HEATERS SUCK sign attached......


update sep 9
Well I got the new gas valve in. THE OLD ONE REFUSED TO SHUT OFF so the water BOILED and then it dumped. I HAD TO BASH THE WATER HOLDER shell to get the new one to fit. THE THERMOCOUPLE DICK sticking out had a shorter threaded rod, but I got it in and I observed the temperature get up and the burner dumped without the pilot dumping, SFSG!!!11 one one. I do not trust it yet, however.

Well it has been 2 days so far. This is what I did to accomplish this feat of impossibility. First, I removed the window and installed OLD steel (I think) screen folded into 3 layers and wedged into the old glass tabs. Second I did the bend on the thermocouple to get it JUST ABOVE the pilot. I speculated that the burner flame messes with the pilot and makes it go higher. Third I REDUCED THE GAS with the main valve. After this, I watched it operate 3 cycles and today (2 days later) I jingled the tenant and was informed 'the tiny torch flame is still there behind the screens'.

I even put the hot water on to drain the tank and watch 3 cycles successfully.

And here is my dose of sarcasm.

The stupid arrester screen that allows flames to go through has apertures that ate TOO TINY to allow oxygen molecules (O2) to go through so it all goes through the window converted into a screen thing (The pilot appeared healthier after the modification)

And yupp, I had to piss all the water out with a garden hose B4 replacing the gas valve. The gas valve has the wires built in and a forward threaded insert so no more weird adapter. I now need to beg for luck on an astronomically gargantuan basis! I hope that I produced an EPIC WIN that I kicked the WHORFOOL's HINEY

hmmmm sound like we are once again having modifications done...:eek:
Taking out the window defeats the FVIR function.

they just want hot water

it seems to be the only way to defeat this dog......

of course the customer does not care that it aborts the
fire safety protocal on the heater....

all they really want is hot water...

all I would like to see is Whirlpool own up to their mistakes......

Who really needs it? It wasn't necessary for decades and water heaters worked fine without it. Now we have this so-called feature with the result that water heaters no longer heat water and everyone's busy working on their gas lines to fix controllers that shouldn't be failing in the first place. Give me the old control boxes that worked, get rid of the flame arrestor and things should be peachy. I was drooling at one of these just this weekend...21 years old and still going strong...huge open window.

The strange thing about this is that the gas valve is not exposed to the combustion heat and should function with or without the FVIR changes. Ruin 100 TC's and the gas valve should still be working. Since it is not a (or the) major problem appears to be that Unitrol Robert Shaw gas valve. Maybe the FVIR kills half of them...but the clean ones (like mine) that are having trouble seem to be experiencing a different failure mechanism.

it was never necessary..but Most work great

Who really needs it? It wasn't necessary for decades and water heaters worked fine without it. .

the story goes is insurance comanies bribed the congress to pass these laws, and any heater company that did not go along with them would not be able to insure themselves
or their rates would go sky high......

sorry , I meant to say the insurance companies "lobbied"
congress to pass these new mandated laws....

in all honesty , they were having terrible fires quite often with the old style water heaters...
Kids and were getting burned alive in garages and in mechanical rooms
houses were catching fire pretty often due to something leaking out of a
paint can set near the heater....

I myself was almost burned alive when I was
about 19 in a waterheater fire.... fooling around out in the
mecahnical room with paint brushes and
cleaning them with gasoline near the water heater....
I was very , very lucky I was not blinded

the New FVIR heaters work great....
RHEEM and BRADFORD WHITE have never had a problem with them...

its only Whirlpool and the stupid dumb asses that designed
this dog that wont admit fault..

I suppose that they too have "lobbied: congress"
to weasel out of recalling them all

What should I do with Whirlpool water heater?

Well I'm sorry to admit that I bought one of these water heater's from Lowe's and it stopped working after 6 months.

I replaced it with a Bradford-White.

My question is, what should I do with the POS Whirlpool? I kinda hate to just throw it out, since it holds water, etc.

Thanks,

DD

I bought a Whirlpool Flamelock, LPG , 1 year ago from Lowes. The old B.W. blew a leak late on a Saturday, Lowes is nearby, blah blah blah. This new one went out about 3 weeks ago.
To shorten this post up I'll say that the thermocouple is fine, checked with a multimeter during lightup, and I have a clean flash arrestor in the bottom of the unit. I also checked for voltage before and after the "circuit breaker" located below and to the right of the gas valve, 22mv in (black wire), 19mv out (white wire).
Lowes did not have a LPG valve in stock, and most of the local plumbing supply places only carried the normal "I could care less" looks.
I called the # on the water heater, got them to send me a new gas valve, under warranty, so no cost to me. The new valve would not be in for a few days because this took place on a Friday. So I pulled the gas valve out of my old B.W. water heater, all the connections lined up and she fired right up even with the old thermocouple in place.
All I had to do was adjust the burner pressure down a bit to eliminate the slight yellow flickers off the ends of the burner flames, the yellow was not present when the Flamelock was in operation before this.
This past weekend I pulled apart the original Flamelock gas valve to see how the pilot circuit is setup. I found out that the white wire from the "circuit breaker" runs up into the temperature sensing element that protrudes into the tank and thru what I figure is a thermistor that must cut off the pilot circuit at some really high water temperature.
I'm figuring the thermistor breaks down internally over time and the pilot won't stay lit. When I get the time I'm going to try and rig up a test stand to put a controlled
heat source on the temperature sensing probe of the gas valve and see if the mv signal to the pilot circuit drops after a bunch of on / off cycles.
I would have to say the the problem I am diagnosing is centered in the RobertShaw gas valve and not the flash arrestor like some people here are saying. When I first started to lose the pilot, upon restart the burner would light right up and burn all blue flames, no yellow at all, stay "burner on" all thru a heat up cycle, shut off and then I could see the pilot slowly lose gas till it also died. I'm pretty sure if the main burner can work at all the pilot will not be starved for air between heat cycles, so pulling out the glass or drilling some holes in the unit won't help.
I don't know if the new gas valve has any changes from my original, but they do look identical. That would explain why the "upgrade" kits seem to have the same problem down the road. The thermistor in the temperature sensing tube would be the quick fix AWH and RobertShaw came up with to replace the left hand threaded thermocouple on the early models.I think I saw in a picture somewhere that left hand thermocouple had a bulge in the tubing back a bit from the coupling head.
Maybe if an AWH or RobertShaw employee is going thru this pile of post they can look into this.
And no, I still have not changed to the new gas valve.
I might just remove the sensing tube first to see if they changed that thermistor to a different spec part. Shes' still working fine with old B.W. gas valve.

Read the above and thought I had already posted as I am in the same boat and did the same thing for a temporary? fix. Did same checks on thermocouple and it was good, replaced just in case because it was cheap and Lowe's had them in stock. Both old and new had about same output 18-20 ma.

Joined this site so I could become a member of the club. Purchased a LPG BFG1F5040T3PV in April 2008, worked fine until this weekend. Water Heater is the US CraftMaster version. Previous heater was American Standard, same manufacture just different brand, and had worked fine just was getting old, so purchased without reading. Really mad at self because I could have got a Bradford at same price. Anyway, reason I quoted this post is that I have done the same thing (installed Old Control Valve In Water Heater) because I didn't want to be without hot water for 2 days while new LPG control value is shipped. Don't know why but the valve is being shipped overnight at no cost and they even gave me a number to call for free installation. If I install the new valve I will do it myself as the installer is A & E Sears, and the reports on them are not that good. And installing the control valve/thermostat is not that hard.

Only thing I see that I am not getting with the old control valve is not having the thermal switch on the thermocouple, which may be a good thing. When I bought the new water heater it came with the skirt and it appears to do a good job as the screen on the bottom was clean.

Will not spend any money on this water heater and when it fails again will probably replace.

Read all 23 pages and this thread will go on for a while.

Received my replacement valve today. I am debating whether to install the new valve or leave the older style control valve/thermostat in. The old valve is working fine. The only thing that I see that I do not have with the old valve is the resettable thermal switch wiring that is on the new valve. The thermal switch never had to be reset so I did not have a problem with that. What exactly does the thermal switch protect against and do I really have a major safety issuse with the old valve? I don't see that it is any different then the previous water heater that was there for years without any problems. I still have the flash back screen in place and have not made any other modifications.

Found this little tid bit of info http://www.macdonaldsupply.com/cust...ges/web_resources/Gas Valve Message 11-08.pdf about "We want to apprise you of an unfavorable service trend with certain Robertshaw gas valves which were used on American residential heaters manufactured between September, 2007 and May,2008 (water heater serial numbers range from 0735 to 0822) The typical consumer call has been “pilot will not hold”. This is also a quote from the same letter "We apologize for the inconvenience this problem may have caused you and your customers. We can assure you that gas valves used after May 2008, incorporate an ECO which is in compliance with our specifications".

Pretty much describes the condition of what I had (serial # 0804) and several others have discussed here. I don't know if the problem has truly been "fixed" on the newer gas valves but I will probably put the new valve in when the weather clears up in a few days and see how long it will last.

monday morning a boatload of calls

got a boat load of whirlpool calls today...

the first was from a poor guy in Houston, with a 1 year old Whirlpool heater installeled up in his attic.. behind the furnace.... wanted to know how to reapir the unit.. he has got troubles


the second guy was from San Deigo, the previous owner had majic markerd the heater with dates every time the reapir man fixed that dog, it had been repaired 5 times in the last 6 years... i told him to jsut throw it out , and he agreed...

then it really began...

I get 4 more calls scattered through the day...
all from Indianapolis, wanting me to repair their Cess-pools, all of them about 2 years old...

I told them to call Raji in India and have the parts sent to them.... then call me back...:D

.This would almost be funny , if it were not for the people that have beed screwed so deeply by whirlpool...

Have this very issue Serial # begins with 0817. No continuity found as tested though the white and black wire running from the thermal cutoff switch once the the water tempture is near the cutoff set at 120 degrees the ECO cuts off the main burner and pilot before reaching the desired temp. After that the pilot will not stay lit until after the water cools down cold then the ECO closes and continuity is present again as tested though the white and black wire running from the thermal cutoff. The thermal switch continuity tested ok so the thermal switch is not the issue.

Missed curlysir's follow up with that very useful information. So much for the plumber claims here that the Robert Shaw valves could not be the problem. Turns out they were, and my serial number in the range mentioned! My serial is #0808.

This explains why there was no indication of any other problem on mine and some others: no air restriction/draft problem apparent, clean FVIR screen, yet the Robert Shaw valve had obviously failed after one or two relights.

Of course the question now is whether or not the replacement Robert Shaw valve is really fixed...only time will tell.

Flame Lock Whirpool Water Heater model NO.?

I have purchased already 3 Whirlpool Flame Lock water heaters from Habitat. These were donated to Habitat for sale by Lowe's, obviously warranty returns with problems. All 3 had removed model and serial numbers so I do not know what models I have. To order parts I need model numbers, otherwise Whirlpool can't locate the replacement parts. Can anyone help me using the pictures below to identify the model? The thermocouple has right-hand threads and manifold tube also right-hand threads. The water heater is similar to what Lowe's has on the floor now, but my does not have the Thermal switch.

When purchased the problem was not thermocouple but the high temperature sensor (HTS) in all 3 cases. That is an internal part (penny value) and I suppose the whole thermostat (gas control valve) needs to be replaced. In first instance I got around by taking the HTS from the 20 year old water heater I was replacing. Second and third time I took it from new similar valves that I happened to find at Habitat and bought it cheaply. These HTS are very easy to replace, problem is to get it. If someone knows where to buy it I will appreciate the information. See the last picture below that shows 2 HTS, one as removed from the gas valve and one with insulation stripped. It would be very easy replaced (silver solder) if the electronic component was available to buy. I do not have the problem with clogged screens. One water heater is installed outside as shown on the picture, one in my garage elevated above the floor 18â€. Also I need outer doors for both. My email jfkn@cox.net.

you are in trouble

that is a new one on me,,,, I have never seen this new peice of junk bdefore

this is not a flame lock water heater.....

that burner assembly is some sort of
energy star type that is close to the same radiant burner assembly that BRADFORD has is their new energy star models..

I cant immagine how bad these must be considering they cant make a normal water heater work corretly..

LOWES dontated some real junk to
habitat for humanity and should be held accountable... being the fact that they scraped off the model numbers and serial numbers should tell you what kind of crap you got there....

I would tell them you to take them back and "dontate " a better water heater to those homes....or you are going to the local news papers.

So at the end of the day, we have one guy saying the screen just gets clogged up, another saying it's too small, another saying it's both. One saying it's the gas valve, many more saying it's the thermocouple, and one guy saying it's the thermal switch.

So do any of you know for certain what the problem is?

All of the above, but it is a different issue on each unit--or group of units anyway. There is no doubt about the Robert Shaw valve/thermostat being the problem on some units (such as mine). This has now been documented from the manufacturer (see curlysir's link.) The emergency cut off in these were failing rendering the valve worthless. If you had a failure in the Robert Shaw valve you wouldn't know it until you replaced the thermocouple and it still didn't work. This has been a common theme in the thread.

Then there were some units where it appears to have only been a TC problem. On others it was a problem with the FVIR screen plugging. The screen for it is too small for the service and it is poorly placed. Lack of appropriate surface area is the norm for many kinds of equipment. I don't think half of the folks doing the design for suction and discharge grates have a clue as to what is needed. I say that from the perspective of having done such designs for process equipment, and re-engineering/modifying some of the messes that have been in my own appliances. They rarely provide sufficient open area.

The point is that none of the explanations fit all of the failures individually. But take them together and they appear to explain all or nearly all of them.
