Carrier furnace ignitor not glowing.

Make sure your water drain on a 92 furnace is open. Like many gas furnaces our furnace uses this hot surface ignitor it lights up like a glow plug every time the burner needs to light so it cycles hot cold thousands of times. Turn the furnace off using the thermostat. Make sure the furnace as at room temperature.

Find the gas supply valve next to or behind the furnace and rotate the valve to the open position typically by twisting counterclockwise. I put a meter on the wires going to the ignitor and found no power during the start up sequence. It eventually cracks and burns out like a burnt out light bulb. Furnace ignitor doesn t glow when the stat calls for heat the blower runs for a while then shuts down then the inducer runs for a while then shuts down at no time does the ignitor glow.

Turn off the furnace. The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. If too much water backs up into the draft inducer it will not allow the pressure switch to close. This is typically the problem if you can hear your furnace click on but it does not fire up.

Stop immediately if you smell gas. A technician told us he changes these all the time. In order to check the ignitor by testing the circuit and inspecting the furnace for visual damage the furnace must be set at room temperature. The goodman furnace may not be receiving an adequate gas supply if the glow ignitor turns on but the furnace cannot ignite.

Turn the furnace off and leave the house. They last about 10 years. Here are a few steps to check your ignitor and determine if it needs to be replaced.
