Pilot Light Goes Out In Wall Heater

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.

Pilot light goes out in wall heater.

You can fix this easily by moving the thermocouple closer to the flame. Pilot goes out the heater won t operate properly if the pilot flickers is too weak or goes out and the cause could also be blockages in the pilot tube. Call a service technician to repair these problems. The number one reason why the pilot light keeps going out is the thermocouple either the thermocouple is going bad or it is dirty and needs to be cleaned.

A leak in the output duct of the furnace could cause air to blow into the area. The flame will go out if the tube is clogged with dirt or debris. Thermocouples work by producing a small amount of voltage when it is heated. The pilot tube supplies gas to the pilot light for combustion.

Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues. So what s the problem. 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.

Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft. Keep every intake air register in your home open and clear to avoid a vacuum effect in the inlet. We know those issues are pretty vague.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. This can happen on excessively windy days or nights. Sometimes pilot lights go out because the flame is set too low. 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.

Another cause of a weak pilot is a faulty. The owner s manual provides information for adjusting the flame.
