Oven shows E017 and will not start, door appears closed

Safety: Turn off power before removing any panels.

• Check door closure: Ensure the door is fully closed and not obstructed by trays or racks. Gently press on the door to see if the error clears.
• Inspect hinge and latch: Look for sagging hinges or a bent latch hook that might prevent the door switch from actuating.
• Access door switch: Remove the top or side panel to reach the door switch assembly near the latch area.
• Test switch: With a multimeter, check continuity of the switch when the door is closed and open. Replace if readings are inconsistent.
• Check wiring: Inspect the harness from the switch to the control board for breaks or loose connectors.
