Oven interior light stays on permanently and does not switch off when the door is closed.

Safety first: Isolate the oven from mains power.

• Check door closure: Ensure the door closes fully and evenly. Fix any hinge or seal issues first.
• Locate door switch: On many Salter ovens, a small plunger switch is located in the frame. Press it manually and listen for a click. If it does not click or feels loose, replace the switch.
• Test switch electrically: Disconnect the switch and test continuity while pressing and releasing. Replace if it does not change state correctly.
• Control board: If the switch is working but the light remains on, the lamp relay or driver on the control PCB may be stuck closed; replace the PCB.

Warning: A permanently lit lamp can overheat the lamp cover and surrounding area over long periods.
