Pilot Light Keeps Going Out On Wall Heater

So what s the problem.

Pilot light keeps going out on wall heater.

In newer heaters a sensor is used to detect the flame from the pilot. Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues. 5 improper air flow or a strong draft blows the pilot out. Looks like a probe that sits right in the flame if the sensor does not.

A leak in the output duct of the furnace could cause air to blow into the area. Another cause of a weak pilot is a faulty. This is the pilot flame that provides the heat. Either the thermocouple is going bad or it is dirty and needs to be cleaned.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. You can fix this easily by moving the thermocouple closer to the flame. The number one reason why the pilot light keeps going out is the thermocouple. 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 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. 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. If your gas furnace s pilot light keeps going out you re probably frustrated and cold. Thorough cleaning should do the trick.

This can happen on excessively windy days or nights. The heat sensor for the pilot light may be faulty. We know those issues are pretty vague. 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. Use a slender needle to gently unclog the tube. The flame will go out if the tube is clogged with dirt or debris.
