So what s the problem.
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.
If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.
We know those issues are pretty vague.
You can fix this easily by moving the thermocouple closer to the flame.
The flame will go out if the tube is clogged with dirt or debris.
Well if your gas furnace pilot light won t stay lit it s usually due to 1 of these 4 issues.
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.
Thorough cleaning should do the trick.
Another cause of a weak pilot is a faulty.
The number one reason why the pilot light keeps going out is the thermocouple.
The pilot tube supplies gas to the pilot light for combustion.
When the water heater pilot light goes out first try relighting it following the directions on the water heater label.
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.
This can happen on excessively windy days or nights.
Thermocouples work by producing a small amount of voltage when it is heated.
In newer heaters a sensor is used to detect the flame from the pilot.
Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out.
This is the pilot flame that provides the heat.
The heat sensor for the pilot light may be faulty.
Use a slender needle to gently unclog the tube.
If your gas furnace s pilot light keeps going out you re probably frustrated and cold.
If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater.
Either the thermocouple is going bad or it is dirty and needs to be cleaned.
