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.
