What CF on the Freezer Display (106-prefix) means

On Kenmore refrigerators whose model numbers start with 106., a Whirlpool-built platform, CF on the freezer display means a communication failure between the main control board and the user interface. The two boards are not exchanging information. You may see the panel behave oddly, temperatures not changing when you press the keypad, or the cooling following old settings. Often the refrigerator keeps running while you cannot adjust it.

Common causes of CF on the Freezer Display (106-prefix)

Cable or harness between the main board and the interface
User interface board
Main control board
A brief power glitch

✓ One safe check you can try

1. Check that the plug is fully seated and the outlet has power. 2. Press the freezer temperature keypad once and see whether the display answers. 3. Pull the plug for a few minutes so the boards can restart, then push it back in firmly. 4. Watch the display for a minute after it starts. 5. If CF returns, note it and call us.

A link failure can be a cable or either board

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

CF on the Freezer Display (106-prefix)CF on the Freezer Display (106-prefix) questions

Is my food at risk?

Often the refrigerator keeps cooling to its last settings, but you cannot trust adjustments. Check the temperatures with a thermometer if CF stays on.

What do the two boards do?

The main control board runs the cooling, and the interface board is what you see and press. CF says that they are not communicating, so the display may not reflect what the refrigerator is doing.

Will you replace a board right away?

Only if testing points to it. A loose cable is the simpler cause and we check it first. A written price comes before any work, and our workmanship carries a 30-day warranty.
