Maytag Refrigerator Error Code CF
Communication failure between boards
Common Causes
- 1Wiring harness issue between main and UI boards
- 2Main control board failure
- 3UI display board failure
If CF prevents temperature control, food safety is at risk. Use a standalone thermometer to monitor fridge (35-38F) and freezer (0F) temperatures.
Step-by-Step Troubleshooting
- 1
Unplug the refrigerator for 5 minutes, then restore power
- 2
Check the wire harness between the main control board (at the bottom rear) and the UI board (behind the door display)
- 3
On French door models, inspect the door hinge wiring harness for broken wires — door flexing damages conductors
- 4
Reseat all connectors on both boards firmly
- 5
If the error persists, test communication signals with a multimeter to identify the failed board
Pro Diagnostic Tip
On Maytag MFI French door refrigerators, the door hinge wire harness flexes with every door opening and wire fatigue is the leading cause of CF codes. Check for frayed wires at the top hinge first — this saves replacing expensive boards.
