Reading the refrigerator display

On a refrigerator the code shows on the control panel or dispenser display. Some models flash a letter or alternate two characters; hold the code in view and note both. KitchenAid pairs the number with a letter group in the manual, so match the exact characters.

KitchenAid is Whirlpool Corporation's premium appliance line. Its dishwashers, ranges, microwaves and refrigerators share Whirlpool boards but use their own panel layouts and numbering in the manuals. The codes apply to model numbers such as KUDS24SEWH1, KUDS01DJSS0 and KHMS155LSS4; check the label on your unit to confirm yours.

What causes Flashing "F"

How to fix it

  1. Cycle the power: unplug the refrigerator or flip its breaker for five minutes, restore power, and see whether the display shows the code again after a few minutes.
  2. Before opening any panel, switch off the breaker or unplug the appliance; this circuit can carry line voltage.
  3. Check that the doors seal and nothing keeps them from closing; look for frost build-up on the back wall of the freezer.
  4. Listen for the evaporator and condenser fans and confirm both turn freely.
  5. Unplug the unit with the doors open for several hours to melt any frost fully, then restart and watch temperatures over 24 hours.
  6. If frost returns, test the defrost heater, sensor and fans in turn and replace the one that fails; call a technician for sealed-system faults.
  7. Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.
