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.

Use a slender needle to gently unclog the tube. You can fix this easily by moving the thermocouple closer to the flame. 5 improper air flow or a strong draft blows the pilot out. Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out.

Thermocouples work by producing a small amount of voltage when it is heated. A leak in the output duct of the furnace could cause air to blow into the area. Thorough cleaning should do the trick. When the water heater pilot light goes out first try relighting it following the directions on the water heater label.

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 can happen on excessively windy days or nights. If your gas furnace s pilot light keeps going out you re probably frustrated and cold. Another cause of a weak pilot is a faulty.

The heat sensor for the pilot light may be faulty. If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. The pilot tube supplies gas to the pilot light for combustion. This is the pilot flame that provides the heat.

We know those issues are pretty vague. Either the thermocouple is going bad or it is dirty and needs to be cleaned. In newer heaters a sensor is used to detect the flame from the pilot. So what s the problem.

The flame will go out if the tube is clogged with dirt or debris. Looks like a probe that sits right in the flame if the sensor does not. The number one reason why the pilot light keeps going out is the thermocouple.
