Possible Causes
Weak backup capacitor or battery on control board,Corrupted EEPROM,Power supply instability to logic circuits,Control PCB failure
How to Fix / Troubleshooting
Safety first: Unplug the microwave before accessing internal components.
User-level actions:
- 1. Check power stability: Avoid sharing the outlet with heavy loads (e.g., heaters) that cause voltage dips. Plug the microwave directly into a dedicated wall socket.
- 2. Power reset: Unplug for 10 minutes to clear temporary memory errors, then reprogram the clock and test.
Technician-level actions:
- Inspect the control PCB for a backup capacitor or battery and test/replace if defective.
- Reprogram or replace the EEPROM if service tools and firmware are available.
- Replace the entire control PCB if memory faults persist.
Note: Persistent E13 errors usually require control board replacement.
