How to Fix / Troubleshooting
Safety first: Unplug the appliance before adjusting door components.
- Step 1 – Inspect door alignment: Check that the door sits squarely in the frame and that the gaps around the edges are even. If the door sags, the hinges may be worn or loose.
- Step 2 – Check latch engagement: Open and close the door while observing the latch hooks entering the cabinet. They should engage fully with the interlock assembly.
- Step 3 – Adjust or replace hinges: Tighten hinge screws on built-in AEG models. If the hinges are bent or worn, replace them.
- Step 4 – Test monitor switch: With the cover removed and power disconnected, test the monitor switch with a multimeter. Replace if it does not change state correctly when the door is opened/closed.
