What to Do When the Ignition Light is Malfunctioning

Troubleshooting Your Furnace

Is your furnace acting up, and the ignition light seems to be malfunctioning? Don’t panic! While this can be concerning, there are several steps you can take to diagnose and potentially resolve the issue before calling in the professionals. Here’s what you need to know:

Check the Power Supply

The first step is to ensure that your furnace is receiving power. Check the circuit breaker or fuse box to see if any switches have tripped or blown fuses that need replacing. If everything appears to be in order, move on to the next step.

Inspect the Ignition System

The ignition system is responsible for lighting the furnace’s burner and should be checked for any signs of malfunction. Look for loose connections, damaged wires, or any visible debris that may be affecting its operation. If necessary, gently clean the ignition components to remove any buildup or corrosion.

Replace the Ignition Sensor

The ignition sensor is a crucial component that detects whether the burner has lit successfully. If the sensor is faulty or dirty, it may prevent the ignition light from staying on. Consider replacing the sensor if cleaning it doesn’t resolve the issue.

Check the Gas Supply

A lack of gas supply can also cause the ignition light to malfunction. Make sure the gas valve supplying your furnace is open and that the gas line is free of any obstructions or leaks. If you suspect a gas leak, evacuate your home immediately and contact your gas provider.

Inspect the Thermostat

Sometimes, the issue may not lie with the furnace itself but rather with the thermostat. Make sure the thermostat is set to the desired temperature and that the batteries, if applicable, are not depleted. Additionally, check for any programming errors or malfunctions that may be affecting its operation.
