Oven interior light does not work, but the oven otherwise functions normally.

Safety first: Turn off power or at least ensure the light circuit is off before changing bulbs.

• Step 1 – Replace bulb: Remove the light cover inside the oven and replace the bulb with the correct high-temperature oven bulb specified by Zline.
• Step 2 – Inspect socket: If a new bulb does not work, inspect the socket for corrosion or burn marks. Replace the socket if damaged.
• Step 3 – Check door switch: If the light is controlled by the door, test the door switch for proper operation and replace if faulty.
• Step 4 – Control relay: If the light is controlled by a button on the panel and the socket and bulb are good, the light relay on the control board may have failed. Replace the control board if necessary.

Tip: Always use bulbs rated for oven use; regular bulbs can fail quickly or shatter.
