Gas Wall Heater Pilot Light Won T Stay Lit

Blast some compressed air through the tube.

Gas wall heater pilot light won t stay lit. You can fix this easily by moving the thermocouple closer to the flame. If the pilot lights but won t stay lit the thermocouple is probably bad. While this is an excellent safety feature a faulty thermocouple may decide arbitrarily that your pilot light is off when you want it on shutting down your pilot light and your furnace. Thermocouples detect pilot lights by sensing the heat they produce.

Pilot light issues are some of the most common problems experienced with gas water heaters. If not then you have a problem with the gas valve. A number of reasons can cause the wall furnace to not light including a damaged thermocouple a clogged pilot. I have a gas wall heater and the pilot won t stay lit.

The pilot light in your hot water heater does more than simply ignite the gas. Without it the water heater won t be able to maintain internal temperatures allowing the water to cool off. This device generates a small electric signal to keep the gas valve open when the pilot is on. You can test it with a multimeter.

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 determines that the pilot light is off it shuts down the flow of gas. If the thermocouple is too far from the flame this can cause the pilot to go out and shut down the propane heater. Or use a single strand of wire and run it through the tube.

Remove the orifice or the pilot light tube from the mounting bracket. I replaced the thermocoupler and the gas valve with a new valve itt general controls b67ra56 and nothing different it still won t stay lit. Listen if there s a hissing sound. 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.

Put everything back together perfectly. An operational pilot light in your furnace means safety from the possibility of a gas leak. When the pilot on your wall furnace does not stay lit your furnace won t heat. Another cause of a weak pilot is a faulty thermocouple.

Every gas appliance with a standing pilot that cycles on and off needs a thermocouple. This pilot light may not always stay lit due to a variety of issues that may affect the gas supply or ignitor. The pilot light in your gas furnace supplies heat to your home. Furnaces of various kinds are gas powered and use a pilot light to supply heat to the unit including standard home furnaces and floor furnaces.
