Error code F dH
Appliance Refrigerator
Quick answer

F dH: the defrost sensor stayed below 40 F on Kenmore and Kenmore Elite 795 bottom-freezer refrigerators; fuse, heater or control board.

Model compatibility

Kenmore reuses codes across series and model years, so F dH 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

Defrost sensor did not rise above 40 F.

Code overview

  • Display: F dH
  • Series: Kenmore and Kenmore Elite 795 bottom-freezer
  • Meaning: during defrost, the sensor never climbed past 40 F

Where the manual points

Three things are named: the fuse, the heater and the control board. Under parts it lists a controller assembly, a defrost heater and a relay on the control board. Looking into any of these belongs to a technician, so write down the code and arrange a visit.
