Possible Causes

Failed control board voltage regulator, Shorted component on logic circuit, Intermittent control board connectors, Electrical noise from failing line filter

How to Fix / Troubleshooting

Safety: Unplug the microwave before removing the control panel.

Preliminary checks:

  • Confirm the outlet voltage is stable and within specification.
  • Unplug the microwave for 10–15 minutes to fully discharge internal supplies, then reconnect.
  • Remove any surge protectors or adapters and plug directly into the wall outlet.

Control board inspection (qualified):

  • Remove the control panel and inspect the PCB for bulging capacitors, burn marks, or corrosion.
  • Check connectors for tight fit and signs of arcing.
  • Measure the low-voltage rails (e.g., 5 V, 12 V) if you have the schematic and tools.

If E14 persists, the main control board typically requires replacement. Board-level repair is complex and should be done only by experienced technicians.
