Microwave shows dE or DE and will not start; may beep when door is opened or closed.

Safety first: Unplug the microwave before any physical adjustment.

• Inspect door hooks: Open the door and inspect the plastic hooks that engage the cabinet. Replace the door if any hook is cracked or missing.
• Check for obstructions: Ensure no food debris or foreign objects are lodged in the latch openings on the cabinet.
• Door alignment: Close the door slowly and check if it sits flush with the cabinet on all sides. If it sags, the hinges may be bent. Gently lifting the door while closing can confirm misalignment.
• Test operation: After cleaning and checking alignment, plug the unit back in and test. If dE remains, the door switch assembly likely needs replacement.
• Next step: Because door interlocks are a safety system, have a qualified technician replace and adjust the door switches and latch if you are not experienced.
