Pilot Light Keeps Going Out On Wall Heater

If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.

Pilot light keeps going out on wall heater.

Looks like a probe that sits right in the flame if the sensor does not. You can fix this easily by moving the thermocouple closer to the flame. Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues. If your gas furnace s pilot light keeps going out you re probably frustrated and cold.

The pilot tube supplies gas to the pilot light for combustion. A leak in the output duct of the furnace could cause air to blow into the area. In newer heaters a sensor is used to detect the flame from the pilot. Another cause of a weak pilot is a faulty.

The heat sensor for the pilot light may be faulty. If the pilot doesn t relight if it goes out right after lighting or if the pilot light keeps going out by far the most common cause is a bad thermocouple. The number one reason why the pilot light keeps going out is the thermocouple. 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.

Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out. 5 improper air flow or a strong draft blows the pilot out. Thermocouples work by producing a small amount of voltage when it is heated. Either the thermocouple is going bad or it is dirty and needs to be cleaned.

We know those issues are pretty vague. The flame will go out if the tube is clogged with dirt or debris. So what s the problem. Use a slender needle to gently unclog the tube.

Thorough cleaning should do the trick. 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. This is the pilot flame that provides the heat.
