Also shown as: CF, cf

Last updated: October 6, 2026

Quick answer: Maytag refrigerator error code CF: control communication failure. The most common cause is loose wire harness between the main board and the display. Try this first — power reset for 5 minutes. If that does not clear it, check the display response.

What causes the CF error?

  • Loose wire harness between the main board and the display
  • Failed main electronic control board
  • Failed display/user interface board
  • Corroded connectors, often from moisture
  • Power surge damaging one of the boards
  • Pinched harness in the door hinge (dispenser models)

How to fix Maytag CF — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power reset for 5 minutes
    Unplug the refrigerator for 5 minutes, then plug it back in. This reboots both boards and re-establishes communication. Check whether the display responds normally.
    Safety warning: Keep the doors closed during the reset so food stays cold.
  2. Check the display response
    After the reset, try changing the temperature settings. If the display accepts changes but they do not take effect, the main board may be the faulty side.
  3. Look at the door hinge wiring
    On models with a through-door dispenser, the harness runs through the door hinge and flexes every time the door opens. A technician can check it for broken wires.
    Safety warning: Do not disassemble the hinge yourself — the door is heavy and the wires are delicate.
  4. Verify the fridge is actually cooling
    Put a thermometer in the fridge and freezer. If temperatures hold while CF shows, the cooling system is fine and the fault is display-side. If it is warming up, treat it as urgent.
    Safety warning: If food rises above 40°F for more than 2 hours, discard perishables.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • CF returns right after the power reset
  • The display is blank or frozen
  • The fridge or freezer is warming up
  • The refrigerator is under warranty

Frequently asked questions

The fridge still cools with CF showing. Is that possible?

Yes. The cooling system can keep running on its last settings while the display link is down. But you cannot change settings until it is fixed.

Can I reset CF myself?

The 5-minute unplug reset is safe to try. If CF returns, the harness or a board needs professional diagnosis.

Is CF the same as SY CF?

No. SY CF is a condenser fan error on some models. Plain CF is the board-to-display communication fault.
