Faulty Igniter

It’s natural for an oven’s igniter to stop working overtime. More often than not, the issue will be with the safety valves not opening properly.

To test the igniter, turn on the oven and watch to see if the igniter begins to illuminate.

If it is glowing, but the burner isn’t lighting within a few minutes, you likely have a faulty igniter on your hands. Using a multimeter, test the igniter to ensure a constant electric current is present.

If there isn’t a constant current, then it’s safe to assume the igniter is dead and you need to replace it.

Damaged Spark Electrode 

Certain ovens are equipped with a spark electrode that’s used to ignite the gas in the burner tube, much like a spark plug.

Any damage to this component – such as cracks in the housing or damage to the electrode tip – can be a sign that this part needs replacing.

Oven thermostat doesn't work

Thermostat Doesn’t Work

Your oven’s thermostat monitors the internal temperature and turns off the current once it reaches the desired temperature.

If your thermostat isn’t working, it could prevent the oven’s igniter from getting the necessary power. Similar to the igniter, you can test the current with a multimeter to identify if the thermostat is the issue.

Temperature Isn’t Calibrated Correctly

If your oven’s display temperature and internal temperature aren’t matching, this is a sign that your gas oven wasn’t calibrated or not calibrated properly.

The wire connection might be loose or burnt as well. Consult the user manual to learn how to properly calibrate the temperature of your oven.
