Summary: In order to fix an ignition lockout on a furnace, the problem must be identified and corrected. Many times, the issue is simply a bad battery.

For example, if the furnace has a broken fan, the engine will not turn over. In this case, the problem must be fixed before the furnace can be used again..
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.
10 Ways About How to Fix Ignition Lockout on Furnace
1. Check the Power and Reset the Furnace
If your furnace is experiencing an ignition lockout issue, the first thing you should do is check to make sure that it has power and hasn’t been accidentally tripped off. To do this, turn off any electrical devices in the immediate area and then check to see if any circuit breakers have been tripped or blown. If you find that there is no power to the furnace, then you can reset it by turning off the main breaker and then flipping it back on.
2. Check for Loose Wiring
Another potential cause of an ignition lockout on your furnace could be loose or faulty wiring in the system. To check for this, carefully inspect all of the wires connected to your furnace and make sure that none are loose or frayed. If you do spot any issues, it’s best to contact a professional plumber or electrician to help you fix the issue.
3. Clean the Furnace Burners
Over time, your furnace’s burners can become dirty and clogged with debris, which can cause ignition lockout issues. To help prevent this, be sure to regularly clean your furnace’s burners with a soft brush or vacuum attachment.

If you are experiencing ignition lockout issues with your furnace, it could also be related to problems with your thermostat. To check for this, make sure that your thermostat is set to “on” and that the temperature is set at a normal level.
