How to Fix / Troubleshooting
Safety: Unplug before panel removal.
External checks:
- Ensure the plug fits tightly in the outlet.
- Try a different outlet to rule out house wiring issues.
Internal checks (qualified):
- Inspect the control board for cracked solder joints, especially around the power input and transformer.
- Resolder or replace the board as needed.
If the problem persists with a known-good outlet, replacing the main control board is usually required.
