Range oven light does not work even after replacing the bulb.

Safety first: Disconnect power before working on the light socket or wiring. Use only bulbs rated for oven use.

Steps:

• Verify bulb: Confirm the replacement bulb is good by testing it in another fixture.
• Inspect socket: Check the oven light socket for corrosion, heat damage, or loose contacts. Replace the socket if damaged.
• Test door switch: Locate the oven door switch and test for proper operation with a multimeter. Replace if it does not change state when the door opens/closes.
• Control relay: If the socket and switch are good, the light relay on the control board may have failed. Replace the electronic oven control if it does not supply voltage to the light circuit when commanded.

Note: Some models allow manual light control from the panel; verify settings before assuming a fault.
