Wall Heater Pilot Light Goes Out

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

Wall heater pilot light goes out.

Gas valve are allowed 30seconds to fall out. Another cause of a weak pilot is a faulty. Stays lit for a few seconds but goes out has a weak yellow flame instead of blue then you most likely have a dirty or restricted pilot light orifice. If this pilot light ever goes out the heater has no way of actually turning on to heat the water or air that your particular type of heater circulates to warm the house or other elements.

This can happen on excessively windy days or nights. A bent or dirty thermocouple. You can fix this easily by moving the thermocouple closer to the flame. If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater.

This is the pilot flame that provides the heat. 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. If it senses that the pilot light has gone out the thermocouple shuts off the gas supply to the flame in order to prevent safety issues with your water heater. Thermocouples work by producing a small amount of voltage when it is heated.

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. A leak in the output duct of the furnace could cause air to blow into the area. The number one reason why the pilot light keeps going out is the thermocouple. In english that means a gas valve is slowed to continue to release gas for up to 30 seconds after the pilot fails.

But once i let go of the button the pilot immediately goes out. There could a fault in the gas valve s main burner solenoid causing it to draw excessive power and starving the pilot flame solenoid. Over time thermocouples can begin to malfunction and shut off the gas supply to the pilot light even if it s burning properly. Does my thermocouple need repl.

If your pilot light. I can light it and depress the pilot switch for 2 minutes. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.
