The oven light will not turn on when the door is opened or when the light button is pressed.

Safety first: Turn off power at the breaker before replacing the bulb or socket.

• Replace bulb: Remove the glass light cover inside the oven, unscrew the bulb, and install a new oven-rated appliance bulb of the correct wattage.
• Test door switch: Locate the door switch (usually in the frame) and press it manually. If the light does not respond, test continuity with a multimeter and replace the oven door switch if faulty.
• Inspect socket: Check for corrosion or heat damage in the light socket. Replace the oven light socket if contacts are burnt.
• Control relay: If bulb, switch, and socket are good, the EOC light relay may have failed; replace the electronic oven control if necessary.
