    Default Propane Grill Regulator Problem??

    Dont know if this belongs in this forum but will try:

    Have an older Sunbeam propane grill with a dual main burner and one side burner.
    So three controls where:
    1- is the side burner,
    2- is the left side of the main burner and
    3- is the right side of the main burner

    If I have either 1, 2 or 3 lit, I get a full flame.

    But as soon as I have any combination of them lit, the flame diminishes big time on all.

    I checked all venturis and there are no spider webs or obstructions. I even removed the valves from the burners therefore elimintating any clogs and reattached to propane tank. You can hear the decrease in the "hissing" sound when 2 of the valves are on.

    Propane tank is newly filled and propane tank operates fine on other grill.

    Has anyone had any problems with a regulator going bad?

    I had one get water in it and freeze over the winter. It would light but not stay lit. replaced regulator and was repaired.

    Yeah right...I already have a junk grill.

    Over the winter I was able to obtain a Broilmaster natural gas P3BLW with the bowtie burner. Going to debut it as soon as winter is done.The Sunbeam is just a backup.

    Go big or don't go at all

    I looked at the infrared ones also. Was not impressed or swayed to go that route. Looked like a lot of cleanup.

    After finishing, turn it up to high, let it sit for maybe 10-minutes, everything turns to ash...wipe it off. Cleanup couldn't be easier. Now, this company's original burner, now off patent protection, is being used by lots of companies because it is better than a conventional burner (it's about 35% IR, charcoal is about 25% and one reason it cooks better than a regular gas grill). But, a regular grill is nearly 100% convection hot air cooking. TEC's newest burner is 100% infrared...it has a glass plate underneath the grate and on top of the burner so there's no convection cooking at all - it's all IR.

    Since EVERY burner works properly by itself the problem is NOT in the controls or orifices. You just don't have enough gas flow, and that could be due to a bad regulator or a cylinder valve that limits the flow in case of a bad leak.

    Turned out to be the regulator. Picked one up from local gas grill house along with an oetiker clamp and a barbed connector. Burner works fine now.

    Only thing is the new regulator only has a single output so I can't use the side burner and the cylinder needs to be rotated 90 degrees an d now I need a bungee to secure it.

    That is why they make close nipples and tees.

    My grill has a wierd habbit of if I turn the bottle on too fast, I barely get a flame...even on high. What I have to do is: turn the bottle off, unhook the hose from the low pressure side of the regulator to "bleed it", reconnect the hose, open the bottle slowly, light the grill, and then I get a decent flame. Cheap Chinese junk... I've talked to other people that have the same problem...

    FWIW, this is a TEC burner...that's the same type of glass as used on a smooth stovetop and you can place a pan on it directly, or on the grates. Temp range from around 200-900 degrees.

    That thing looks like it should be at the Space Station

    There is a safety mechanism in the regulator in case of a leak. You can inadvertently activate the safety device without having a gas leak. This typically occurs when you turn on your control knobs before you turn on the LP tank valve, opening the propane cylinder too fast or shutting the cylinder off while the burners are still on.
