Pilot light keeps going out on gas wall heater.

The water heater pilot light is a small flame that ignites the gas burner on your water heater. The flame will go out if the tube is clogged with dirt or debris. This is the pilot flame that provides the heat. 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. Turn the thermostat to its lowest setting. Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out. The number one reason why the pilot light keeps going out is the thermocouple.

Gas heaters whether they warm up air or water in a home rely on a pilot light to trigger the flame of the actual heater. Another cause of a weak pilot is a faulty. Use a slender needle to gently unclog the tube. 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.

So what s the problem. Either the thermocouple is going bad or it is dirty and needs to be cleaned. A leak in the output duct of the furnace could cause air to blow into the area. If you have a natural or propane gas water heater chances are the pilot has gone out.

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. Lighting the pilot light on a gas heater is simple to do. Looks like a probe that sits right in the flame if the sensor does not.

Turn the gas knob to the off setting and wait 5 minutes to clear out any gas. The pilot tube supplies gas to the pilot light for combustion. This can happen on excessively windy days or nights. The heat sensor for the pilot light may be faulty.

Thorough cleaning should do the trick. 5 improper air flow or a strong draft blows the pilot out. In this hvac training video i show up close how the thermocouple pilot light and gas valve work on a water heater furnace fireplace as well as other ap. If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.
