Pilot light goes out in wall heater.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. If this pilot light ever goes out the heater has no way of actually turning on to heat the water or air that your particular type of heater circulates to warm the house or other elements. This can happen on excessively windy days or nights. Other problems like low gas pressure a loose or faulty thermocouple or a gas control valve that s not working right can also cause the pilot light to keep going out.

The flame will go out if the tube is clogged with dirt or debris. We know those issues are pretty vague. Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues. Another cause of a weak pilot is a faulty.

So what s the problem. Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out. Sometimes pilot lights go out because the flame is set too low. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.

Thermocouples work by producing a small amount of voltage when it is heated. A leak in the output duct of the furnace could cause air to blow into the area. The initial flame of the pilot heats the thermocouple which will signal the valve to stay open and keep the pilot lit and the propane heater functioning. You can fix this easily by moving the thermocouple closer to the flame.
