Whirlpool refrigerator error codes: most of what the display shows is a setting, not a fault.

Not a fault. The cooling was switched off at the panel — the lights work, the fans may run, and nothing gets cold. It happens during a cleaning, a move, or a long press on the panel.

1. Press and hold the two buttons the display names for Cooling On/Off (on most French doors, Lock and Temp together) for three seconds until Cooling Off goes out.
2. On a model with a temperature display, the temperature settings show again once cooling is on.

Cooling comes back on; give it 24 hours to reach temperature. A refrigerator that stays warm with cooling on and no state showing is the refrigerator symptom page.

Not a fault. The refrigerator is in the mode the store floor uses — the lights and the display work, the cooling never runs.

1. The display reads Showroom (some print it only when a button is pressed).
2. Press and hold the pair of buttons the use-and-care guide names for Showroom on your model (on many French doors it is the same Lock-and-Temp hold as Cooling On/Off) for three seconds until the word goes out.

Cooling starts once the mode is off; give it 24 hours. The guide for the exact model is on whirlpool.com by model number and names the pair.

Not a fault. A door has been open more than about five minutes; the alarm chimes and the door icon shows. On a French door it is as often the freezer drawer as a door.

1. Push each door and the freezer drawer shut, firmly; a drawer stops a quarter inch short when a box is sitting up behind it.
2. A door that drifts back open is a refrigerator not tilted back enough — raise the front leveling feet a half turn each so the doors swing closed on their own.
3. The gaskets are clean and seal all the way around; a gasket folded under at a corner holds the door off its switch.

Close the door and the alarm stops. If the alarm sounds with every door shut tight, the door switch is the part — a service call. Press any button to silence it meanwhile.

Not a fault. The power went out and came back; the display blinks PO (and may flash the warmest temperature the compartments reached) until it is acknowledged.

1. Press the button the display names (Confirm, or any button on some models) to clear it.
2. If the flashed temperature was over 40°F in the fresh-food side for more than a few hours, look at what is in it before the next meal.

Nothing to fix. PO with no outage in the house is a plug loose in the outlet.

Not a fault. Six months of use (or the gallons the control counts) have passed since the filter was reset; the dispenser may slow before it is changed.

1. Change the filter — it turns out a quarter turn in its housing (inside the top of the fresh-food compartment on most French doors, in the base grille on a side-by-side) and the new one turns in until it stops.
2. Run about 4 gallons through the dispenser to clear the air and the carbon fines.
3. Press and hold the Filter button for three seconds until the light resets.

The light resets. A dispenser still slow with a new filter is the inlet valve or frozen water in the line — the refrigerator symptom page.

Not a fault. The ice maker was switched off at the panel (or its wire arm was lifted), so the bin stays empty.

1. Press the Ice Off (or Ice Maker) button once; the icon goes out when the ice maker is on.
2. Inside the freezer, an ice maker with a wire arm has the arm down.
3. A new refrigerator takes about 24 hours to make its first full bin, and the first two or three bins go down the sink.

Turn it on and give it a day. An ice maker that is on, with water at the dispenser, and makes nothing in 48 hours is a service call.

Not a fault. The dispenser and the panel are locked so nothing dispenses when a child leans on the paddle; the lock icon shows.

1. Press and hold Lock for three seconds until the icon goes out.

The dispenser and the panel answer again.

Not a fault. The lights, the display, the dispenser and the alarms are off for the Sabbath; cooling runs as normal.

1. Press and hold the buttons the display names for Sabbath (on most models the same pair as Cooling On/Off, or Temp alone) for three seconds until the display wakes.

The lights and the dispenser come back. The mode ends by itself after the time the control allows on some models.
