Pilot Light Keeps Going Out On Wall Heater

This can happen on excessively windy days or nights.

Pilot light keeps going out on wall heater.

The flame will go out if the tube is clogged with dirt or debris. Either the thermocouple is going bad or it is dirty and needs to be cleaned. The number one reason why the pilot light keeps going out is the thermocouple. If your gas furnace s pilot light keeps going out you re probably frustrated and cold.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out. When the water heater pilot light goes out first try relighting it following the directions on the water heater label. 5 improper air flow or a strong draft blows the pilot out.

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. The pilot tube supplies gas to the pilot light for combustion. In newer heaters a sensor is used to detect the flame from the pilot.

So what s the problem. You can fix this easily by moving the thermocouple closer to the flame. We know those issues are pretty vague. Thermocouples work by producing a small amount of voltage when it is heated.

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. Use a slender needle to gently unclog the tube. Thorough cleaning should do the trick. Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues.

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. Another cause of a weak pilot is a faulty. A leak in the output duct of the furnace could cause air to blow into the area.
