What CF on the Freezer Display (106-prefix) Means
CF in the freezer display of a 106-prefix Kenmore refrigerator reports a communication failure between the main control board and the user interface. The appliance usually keeps cooling on its last setting while the console stops responding.
Common Causes of CF on the Freezer Display (106-prefix)
- A wire harness between user interface and main board loose
- A failed user interface control
- A failed main control board
🔧 One Safe Check You Can Try
Unplug the refrigerator for five minutes and restore power; a link fault that reappears at once is a wiring or board matter rather than a passing upset.
⚠ Why You Shouldn't Go Further Than That
- Both boards are live whenever the appliance is plugged in, and the interface harness often runs through a door hinge.
- A hinge harness refitted carelessly chafes through within a season.
- Ordering one board on a guess when either end could be the fault is an even bet at an uneven price.
