User Suggested Solutions

Inspect the igniter for cracks or damage. If damaged, replace the igniter. Ensure the oven is unplugged and the gas supply is turned off before starting. Remove the oven bottom panel to access the igniter, disconnect the wires, and replace it with a new one.
Check the burner ports for clogs. Use a thin wire or a needle to clear any debris blocking the ports. Ensure the oven is off and cool before cleaning.
Test the safety valve with a multimeter to check for continuity. If it shows no continuity, it needs to be replaced. Ensure the oven is off and gas supply is disconnected before replacing the valve.
