How to Fix / Troubleshooting
Safety first: Unplug the microwave before accessing internal components.
- Step 1 – Confirm symptom: Place a cup of water inside and start cooking. If the timer counts down but there is no sound of the transformer or fan, suspect an output drive issue.
- Step 2 – Inspect wiring: With the cabinet removed, check wiring from the control PCB to the HV transformer and fan. Ensure connectors are secure.
- Step 3 – Check relays: On the control PCB, identify the main power relay. Inspect for burn marks or cracked solder joints. Resolder if necessary.
- Step 4 – Replace control PCB: If the relay coil is not being energized or contacts are burnt, replace the relay or the entire PCB.
