How to Fix / Troubleshooting
Safety: Unplug before inspection.
Steps:
- 1. Ventilation: Ensure adequate clearance around the microwave and that vents are not blocked.
- 2. Usage pattern: Note if shutdown occurs only after long, high-power runs. This suggests thermal protection is activating.
- 3. Check plug and socket: Wiggle the plug gently (while not operating) to see if there is any looseness. Replace worn sockets.
- 4. Internal inspection (for competent DIYers): Check for loose spade connectors on the mains input, thermostats, and control PCB. Tighten or reseat as needed.
- 5. Replace faulty thermostat: If a thermostat opens prematurely (at low temperature), replace it with a Logik-compatible part.
