Pilot Light Keeps Going Out On Wall Heater

Thermocouples work by producing a small amount of voltage when it is heated.

Pilot light keeps going out on wall heater.

If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. 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. Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out.

If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft. The number one reason why the pilot light keeps going out is the thermocouple. Use a slender needle to gently unclog the tube. The heat sensor for the pilot light may be faulty.

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

You can fix this easily by moving the thermocouple closer to the flame. This is the pilot flame that provides the heat. The flame will go out if the tube is clogged with dirt or debris. If your gas furnace s pilot light keeps going out you re probably frustrated and cold.

In newer heaters a sensor is used to detect the flame from the pilot. 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 can happen on excessively windy days or nights. 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. We know those issues are pretty vague. So what s the problem.
