What Causes Ignition Lockout on Furnace?

There are many reasons that can cause your furnace to have an ignition lockout. Such as:

1. Faulty Ignition System

If your furnace’s ignition system is not functioning properly, this can cause the unit to have an ignition lockout. It may also cause the furnace to emit an error code or indicator light, which can give you further clues as to what is causing the ignition lockout.

2. Dirty or Malfunctioning Flame Sensor

If your flame sensor is dirty or not working properly, this can cause your furnace’s ignition system to have an ignition lockout. To help prevent this issue, be sure to routinely clean or replace the flame sensor.

3. Faulty Gas Valve

If your furnace’s gas valve is malfunctioning, this can lead to an ignition lockout on your unit. To help prevent this issue, be sure to keep an eye on any error codes that your furnace may display and have a professional inspect the gas valve if any issues arise.

4. Dirty Filter

A dirty filter can reduce the flow of air that passes through your furnace, which may prevent the pilot light from staying lit. If you notice that your furnace is having trouble starting or sustaining a fire, it may be time to replace or clean your furnace’s filter.
