1. Inspect the Igniter

For gas ovens, the igniter plays a crucial role in heating. It assists in drawing electrical current through the safety valve, allowing gas to ignite. If your oven isn’t heating up, you may need to repair or replace the igniter.

To check the igniter:

1. 
   

   Locate the Igniter:

   
   
   
   
   • Open the oven door to find the igniter, which is usually situated near the burner assembly at the bottom of the oven.
   
   
   
   


2. 
   

   Turn on the Oven:

   
   
   
   
   • Set the oven to a baking mode (such as Bake) and observe the igniter. It should glow bright orange or yellow within a minute of being turned on.
   
   
   
   


3. 
   

   Observe Ignition:

   
   
   
   
   • If the igniter glows but the gas does not ignite within one minute, this indicates a potential issue with either the igniter or the safety valve. In this case, the igniter and/or safety valve may need replacing.
   
   
   
   


4. 
   

   Turn Off the Gas:

   
   
   
   
   • If the igniter does not glow at all, switch off the gas supply to the oven for safety.
   
   
   
   


5. 
   

   Check for Continuity:

   
   
   
   
   • Using a multimeter, set it to the resistance setting (ohms). Disconnect the igniter’s wiring harness and place the multimeter probes on the igniter terminals. If the multimeter reads “0” or a very low number, the igniter is functioning. If it reads “infinity,” the igniter lacks continuity and needs replacement.
   
   
   
   


6. 
   

   Replace if Necessary:

   
   
   
   
   • If the igniter fails the continuity test, replace it with a new one. Ensure you follow the manufacturer's instructions for installation.
   
   
   
   


7. 
   

   Test the Oven:

   
   
   
   
   • Once the new igniter is installed, turn on the oven to check if it now heats up correctly. If it still does not heat, proceed to the next step.
   
   
   
   

2. Examine the Spark Electrode

The spark electrode is responsible for igniting the gas in the bake or broil burner. If it’s broken or malfunctioning, your oven will not heat.
