Error code F1 Lo/Hi
Appliance Refrigerator
Quick answer

F1 Lo or F1 Hi signals a freezer compartment temperature sensor failure on Kenmore 111-prefix bottom-freezer refrigerators.

Model compatibility

Kenmore reuses codes across series and model years, so F1 Lo/Hi may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Freezer sensor fault (low or high reading).

A Kenmore bottom-freezer refrigerator with a model number starting 111 shows F1 Lo or F1 Hi when the freezer compartment temperature sensor has failed. Lo and Hi are the low or high reading.

The manual’s steps

  1. Unplug the refrigerator.
  2. Look over the freezer temperature sensor wiring that runs to the control board and check it for damage.
  3. Repair any broken wires.
  4. If the wiring is sound, the sensor circuit is measured from the control board, and the freezer temperature sensor is replaced when the reading falls outside the range the manual gives.

That last measurement is meter work for a technician. The freezer temperature sensor is the only part listed, and the manual adds that the codes reset once the failure is repaired.

Related codes

FD Lo/Hi is a freezer defrost sensor failure. i5 Lo/Hi is the ice maker temperature sensor, and iD Lo/Hi is the ice room temperature sensor.
