How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow it to cool before further use.
- Step 1 – Improve ventilation: Ensure there is adequate clearance around the microwave as specified in the Bauknecht manual. Do not enclose it tightly.
- Step 2 – Clean vents and filters: Remove grease filters (if present) and clean them. Vacuum dust from intake and exhaust grills.
- Step 3 – Avoid long continuous runs: For heavy use, allow short breaks between cycles to prevent overheating.
- Step 4 – Professional check: If the problem persists, a technician should test the cooling fan motor and thermal cut-outs, replacing any weak or faulty components.
