Pilot Light Keeps Going Out On Wall Heater

A leak in the output duct of the furnace could cause air to blow into the area.

Pilot light keeps going out on wall heater.

Another cause of a weak pilot is a faulty. Use a slender needle to gently unclog the tube. This can happen on excessively windy days or nights. The heat sensor for the pilot light may be faulty.

If your gas furnace s pilot light keeps going out you re probably frustrated and cold. When the water heater pilot light goes out first try relighting it following the directions on the water heater label. The number one reason why the pilot light keeps going out is the thermocouple. 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.

You can fix this easily by moving the thermocouple closer to the flame. Looks like a probe that sits right in the flame if the sensor does not. The flame will go out if the tube is clogged with dirt or debris. We know those issues are pretty vague.

Either the thermocouple is going bad or it is dirty and needs to be cleaned. The pilot tube supplies gas to the pilot light for combustion. So what s the problem. 5 improper air flow or a strong draft blows the pilot out.

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 your pilot light re lights easily after going out overnight it s possible it was blown out by a draft. This is the pilot flame that provides the heat.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. 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.
