Communication failure
Common Causes
- 1Wiring harness fault

Step-by-Step Troubleshooting
- 1
Unplug the refrigerator for 5 minutes, then restore power
- 2
Check the wire harness between the main control board (bottom rear) and the display board
- 3
Reseat all connectors firmly on both boards — oxidized pins cause intermittent failures
- 4
Look for corrosion or burn marks at connector pins on either board
Pro Diagnostic Tip
On Amana side-by-side and top-freezer models, the wire harness between boards is shorter and less prone to flexing damage than French door models. Check the connector pins for corrosion first — reseating oxidized connectors resolves about 40% of CF cases on Amana units.
