Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the microwave before removing the control panel or accessing internal wiring.
User-level checks:
- 1. Confirm stable power: Plug the microwave into a known-good outlet. Avoid power strips and surge protectors that may be faulty.
- 2. Observe behavior: Note if the unit shuts off when using specific functions (e.g., high power, fan) which may indicate internal power stress.
Advanced steps:
- 3. Inspect control board connections: Remove the control panel and reseat all connectors to the main PCB.
- 4. Visual inspection: Look for bulging capacitors, burnt resistors, or discoloration on the control board.
- 5. Replace control board: If E14 persists and visual signs of failure are present, replace the main control board.
Because this involves live-voltage circuitry, board replacement should be done by a qualified technician.
