Pilot Light Keeps Going Out On 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 keeps going out on wall heater.

Thorough cleaning should do the trick. 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. The flame will go out if the tube is clogged with dirt or debris.

Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out. So what s the problem. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft. Another cause of a weak pilot is a faulty.

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. When the water heater pilot light goes out first try relighting it following the directions on the water heater label. This can happen on excessively windy days or nights. The heat sensor for the pilot light may be faulty.

5 improper air flow or a strong draft blows the pilot out. We know those issues are pretty vague. In newer heaters a sensor is used to detect the flame from the pilot. Thermocouples work by producing a small amount of voltage when it is heated.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. The number one reason why the pilot light keeps going out is the thermocouple. The pilot tube supplies gas to the pilot light for combustion. If your gas furnace s pilot light keeps going out you re probably frustrated and cold.

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. This is the pilot flame that provides the heat.
