not fried thermocouples in flame lock water heaters
A three month old whirpool flame lock water heater has developed the shut off problem. I installed a new control valve sent out by whirlpool. I then replaced the thermocouple. I noticed that the galvanized steel part that holds the thermocouple appeared to be damaged. It looked like the zinc plating on the nut and the bracket has been burnt off. If the base of the thermocouple gets hot, like hot enough to damage the zinc coating on the part that holds the base of the thermocouple, could that heat at the base reduce the temperature differential between the top and bottom of the thermocouple and temporarily reduce the output which would cause shut down? Has anyone measured thermocouple output during heating cycle when shut down occurs? My guess is that the combustion chamber is too hot around the base of the thermocouple.
Also is there a test to determine if the filter is clean enough? Thanks
A LEMON in waiting? (new Whirlpool UG1H5040T3NV Gas Water Heater)
I got a new gas water heater installed last night. They quoted a Rheem, but when the installer came out he said the quoter thought it was a tankless and he suggested a Whirlpool. I've had good luck with Whirlpool appliances in the past, so I said OK. But I woke up in the middle of the night nervous about the way it happened and wanted to check on rebate and tax credit potential... I googled the model number ( Whirlpool UG1H5040T3NV ) -- needless to say, I was horrified!
Finally at 4am after searching, I decided that I would cancel the check this morning and ask for a different water heater. I called the plumber to discuss and and he was emphatic that this is a very good water heater and he stands by it. I mentioned the law suit and he said he remembered the problem a couple of years ago (was even contracted for the mass repair work by Whirlpool), but that Whirlpool redesigned the unit to now use a "burner assembly" which is like a coil, not a flame (is this true?) and that he hasn't had a problem with them any longer. He offered to double his labor warranty (to 2 years) and said that if I have any problems with it he'll swap it for a unit of my choosing.
I was worried that I got some old inventory, but I checked and they are still selling this model at Lowes.
I feel like I have a "time bomb of hassle" ticking in my house... Next time I will do my research beforehand now that I know about terrylove.com.
I will wave some chicken bones over the warranty registration form before I send it in...
Any other guidance welcome. Thanks for this thread. Too bad I didn't see it sooner.
