How to Fix / Troubleshooting
Safety: Unplug the microwave before removing the control panel.
User-level steps:
- 1. Verify power stability: Frequent power cuts or brownouts can cause clock resets. If possible, connect the microwave to a stable circuit.
- 2. Reset and reprogram: Unplug for 5 minutes, plug back in, and set the clock according to the manual. Monitor whether it holds time.
Technician-level steps:
- 3. Inspect control PCB: Check for a backup capacitor or battery and test/replace if faulty.
- 4. Update or replace PCB: If available, update firmware or replace the control PCB with a Sage-compatible board.
If the clock continues to lose time despite stable power, a control board replacement is usually required.
