Oven light will not turn on when door is opened or when light switch is pressed.

Safety First: Turn off power before replacing the bulb or working on the light socket to avoid electric shock.

Step-by-step:

• Replace bulb: Remove the light cover inside the oven and replace the bulb with a high-temperature appliance bulb of the correct wattage.
• Test door switch: Press the door switch plunger by hand and listen for a click. If it feels loose or does not click, replace the oven door switch.
• Check light switch: On models with a separate light switch on the control panel, test for continuity when switched on. Replace the light rocker switch if open.
• Inspect socket and wiring: If the bulb and switches are good, inspect the light socket and wiring for burns or loose connections. Replace the oven light socket if damaged.
