Question about Heating & Cooling

1 Answer

Patio Heater starts but flame is low and it goes out quickly. Presumably this has nothing to do with the pilot light or starter flame because the heater main flame has been started.

There are two heaters which were just put back into service after the winter. They are both acting the same way. The tanks were just filled. The main flame was OK at first but after one time they are puny and go out easily. One might suspect the tank safety valves, the regulators and ... what else? I don't think the pilot light is needed after the main flame has been ignited.

This sound like the thermocouple or flame sensor is bad .
Thermocouple is connected from gas valve and it sits next to pilot so when flame is established this heats up and tells the unit to stay on ,same as a flame sensor

My patio mushroom heater lights up ok but keeps going out by itself after about 5 to 10 minutes and then can be started again inatantainiously by starting pilot light and away you go until it goes out...


Hello,
Here's a few things to check. When you light the pilot, is it a strong blue pilot flame, a weak blue flame or a lazy yellow flame? Is it heating the thermocouple enough to make it red hot after a few minutes? If the pilot is small blue or lazy yellow flame, it may be dirty and need cleaned. When the burner lights, the weak pilot flame may diminish causing the thermocouple to cool off enough to shut down the main burner. Clean the dirty pilot orifice by using a can of compressed air with attached straw. (The same canned air you use to clean computer keyboards) Blow it into the pilot assembly where the pilot flame burns out from and blow thru the air holes on the side, if applicable. You might also check the thermocouple itself to make sure the tip is not partially burn't off. It should be a smooth, rounded tip. Replace the thermocouple if cleaning the pilot orifice doesn't solve the problem. Douglas

Your thermocoupler seems at fault. The thermocoupler is that probe that sits in the pilot flame. It controls the main fuel valve. Make sure that probe is in the pilot flame, better at the tip of the flame and hold the button down for a minute or so after lighting the pilot. If pilot extinguishes, the coupler is faulty. If pilot stays on the heater should fire up when you let up on the pilot button.. Good luck

Patio heater ignites and stays lit with pilot. Then goes out.

Patio Heater pilot lights won't stay lit


crappy pilot flame (not properly heating the thermocouple), bad thermocouple, thermocouple loose where it screws into the pilot safety valve, bad safety valve magnet.

One or more of those is the problem.

Oh...there is also a saftey switch...in case it tips over. It will also cause the pilot to not stay lit (if the switch or wires that go to i are faulty)

You have to hold the button down for 30 seconds at least before turning the knob to ON. If you are doing this and it still goes out after you let up on the knob, then it needs a new flame sensor, or thermocouple. Same thing different names.
