Pilot Light Keeps Going Out On Wall Heater

In newer heaters a sensor is used to detect the flame from the pilot.

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. Thorough cleaning should do the trick. 5 improper air flow or a strong draft blows the pilot out. 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.

Use a slender needle to gently unclog the tube. When the water heater pilot light goes out first try relighting it following the directions on the water heater label. Looks like a probe that sits right in the flame if the sensor does not. Another cause of a weak pilot is a faulty.

Thermocouples work by producing a small amount of voltage when it is heated. The heat sensor for the pilot light may be faulty. Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.

The pilot tube supplies gas to the pilot light for combustion. Either the thermocouple is going bad or it is dirty and needs to be cleaned. 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. This is the pilot flame that provides the heat.

A leak in the output duct of the furnace could cause air to blow into the area. The number one reason why the pilot light keeps going out is the thermocouple. So what s the problem. If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater.

We know those issues are pretty vague. The flame will go out if the tube is clogged with dirt or debris. You can fix this easily by moving the thermocouple closer to the flame.
