KitchenAid Refrigerator F3E1 Error Code

Fresh food temperature sensor fault on KitchenAid refrigerators.

F3E1
May need a pro

The thermistor that reads the fresh food section has dropped out, or its wiring has. With no reading to go on, the control has to guess, so the fridge side may drift warm or start freezing lettuce. A loose connector in the harness can cause it just as well as a failed sensor.

Compatible models

KitchenAid lists F3E1 among the F codes for its French door bottom freezer refrigerators and doesn't name model numbers.

Difficulty

Try the basic checks, but the usual fix is a technician's job.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix KitchenAid F3E1

  1. Cut power for a minute

    Unplug the fridge or turn off its breaker for one minute, then switch it back on. Check that cooling is on and watch the display for a minute to see if the F starts flashing again.

  2. Measure the real temperature

    Set a thermometer in a cup of water on the middle shelf and read it after several hours. A reading of 37 to 40°F (3 to 4°C) means the fridge is still holding temperature while you wait for service.

  3. Move food that's at risk

    If the water reads above 40°F (4°C), pack milk, meat and leftovers into a cooler with ice until the repair.

When to call a technician

A code that comes back after the reset needs a technician to meter the sensor and the harness at the control board. Both sit behind interior panels.
