Error code F027
Appliance Range
Quick answer

F027 on a Kenmore range: communication between the user interface board and the relay board cannot be initiated. Steps from the manual and when to call.

Model compatibility

Kenmore reuses codes across series and model years, so F027 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

Communication between the user interface board and the relay board cannot be initiated.

F027 on a Kenmore range

  • Shown: F027
  • Means: communication between the user interface board and the relay board cannot be initiated
  • Models: electric slide-in Elite models 790.4131, 790.5256 and 790.4255, plus freestanding Kenmore ranges whose model numbers begin with 790

Recommended order

  1. Pause power for 30 seconds, then bring it back.
  2. If the code is back, remove power and review the wiring between the user interface control board and relay control board; secure loose wires or replace a harness that shows damage.
  3. After a recent board swap, verify the part number against the range’s model number, since the wrong part may have been fitted.
  4. Otherwise relay control board first, user interface control board second.
