To troubleshoot a GE gas oven that will not heat, check the oven igniter, pilot light, spark module, thermocouple bulb, oven safety valve, oven valve and pressure regulator and gas connection. Find the oven's manual, if possible, and follow the instructions for troubleshooting.
If a gas oven will not heat, there are several parts to check before calling a repairman.
- Oven igniter or glow bar — If the oven igniter glows for 90 seconds without igniting the gas, it might need to be replaced. This is a very common issue. If the igniter is not strong enough, gas may not even be permitted through the safety valve.
- Pilot light — If the oven has a pilot light instead of an igniter, check if the flame is large enough and the correct color: the flame should be blue, not yellow. The pilot light must be hot enough to tell the safety valve to open. This can be fixed by cleaning the pilot light or replacing it. It is also possible that the pilot light supply hose has a leak in it.
- Spark module — If the oven has a pilot light created by a spark and is not lit all the time, it is possible the spark is not being created. Check whether a spark can be seen when the oven is being turned on.
- Thermocouple bulb — The thermocouple bulb is what the igniter or pilot light heats up to tell the safety valve to release. If the bulb is broken or misaligned, it will not function properly.
- Oven safety valve — The oven safety valve is what allows the gas to come from the pipes into the ignition area. The valve can be broken, though this is rare. If it is broken, it will need to be replaced.
- Oven valve and pressure regulator — The oven valve and pressure regulator are what controls the flow of the gas into the oven. It is very unlikely that this is malfunctioning.
- Gas connection — Lastly, check that the oven is properly hooked up to the gas connection.
