Friedrich gas furnace pilot light.

In these systems there is no pilot light. You re probably familiar with a standing pilot light the little blue flame that sits in front of one of the furnace burners. The pilot light is a small flame that is either lit manually and remains burning around the clock or is lit. If the knob won t go in fiddle with it until it does.

Naturally an unreliable pilot light is something that you should worry about and fix as soon as you notice it. Some furnaces have an electrical system to ignite the gas. Any gas furnace uses a pilot light to trigger the burners to heat your home. However there are many different things that can cause a pilot light to repeatedly go out.

I have inlaws who have an old friedrich gas furnace with an intermittent pilot light going out. A properly functioning pilot light in your furnace means reliable heat in your home and safety from the possibility of gas leaks. This is relatively simple technology though not very fuel efficient. A gas furnace s standing pilot in which the flame is lit at all times is sometimes referred to as a pilot light but no matter what you call it its purpose is to serve as a small ignition flame for the gas burner.

If the pilot light won t stay lit the thermocouple a safety device might be malfunctioning. After waiting for 10 minutes use the following procedure to relight the pilot light. In these systems the pilot will only light in the case of hot surface igniters the igniter surface heats when the thermostat makes a command for heat. It seems to go out more often when the wind blows a little stronger.

Push in the knob and hold it in. If your furnace has a small round knob on the gas valve with the words off on pilot you have a standing pilot ignition. Standing pilot lights are common in older furnaces but many newer furnaces have intermittent pilot lights or hot surface igniters. If your pilot light goes out all you need to.

If this electric ignition system malfunctions call a professional service person. Instead an electric element heats up and ignites the burners.
