Whirlpool, Maytag, and KitchenAid refrigerators share the same controls — and several of their “codes” are actually status messages, not faults. Here’s what each means, what to try first, and when to call a technician.

Whirlpool / Maytag refrigerator error codes at a glance

Codes vary by model — check your manual if yours isn’t listed.

The most common codes — and how to fix them

PO — power outage (not broken)

“PO” just means the power went out while you were away (you may see “confirm” flashing). Try first: press the button to dismiss it, and check that your food stayed cold. No repair needed.

Flashing “6” — normal

The 6th Sense system is working to bring the temperature back down (after the door was open or warm food went in). It clears on its own once the fridge recovers.

CF — communication failure

The main board and the display lost communication. Try first: unplug for 5 minutes. If CF returns, the boards or wiring need service.

Flashing “F” — sensor/control

A sensor or control fault. Try first: a 5-minute reset; if it persists, it needs a diagnosis. See also fridge not cooling.

The bottom line

Most fridge codes point to a fan, a sensor, a defrost part, or are just a status message — and a manual defrost or reset clears many of them. When a part is involved, repairing is almost always cheaper than replacing (a sealed-system or compressor failure on an older unit is the main exception). If a code won’t clear, we repair Whirlpool, Maytag and KitchenAid refrigerators (and every major brand) across DFW, usually same-day. Not sure yours is worth fixing?
