Pilot Light Keeps Going Out On Wall 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.

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. Either the thermocouple is going bad or it is dirty and needs to be cleaned. 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.

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. This can happen on excessively windy days or nights. If your gas furnace s pilot light keeps going out you re probably frustrated and cold.

The flame will go out if the tube is clogged with dirt or debris. We know those issues are pretty vague. In newer heaters a sensor is used to detect the flame from the pilot. Use a slender needle to gently unclog the tube.

Thermocouples work by producing a small amount of voltage when it is heated. 5 improper air flow or a strong draft blows the pilot out. The number one reason why the pilot light keeps going out is the thermocouple. You can fix this easily by moving the thermocouple closer to the flame.

A leak in the output duct of the furnace could cause air to blow into the area. The pilot tube supplies gas to the pilot light for combustion. 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. Looks like a probe that sits right in the flame if the sensor does not.

When the water heater pilot light goes out first try relighting it following the directions on the water heater label. Thorough cleaning should do the trick. This is the pilot flame that provides the heat.
