Quick answer
Communication between the user interface board and the relay board cannot be initiated. Here is what the owner's manual says to check on a Kenmore range.
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 thiscode means
Communication between the user interface board and the relay board cannot be initiated.
F027 sits in the manual next to F025 and carries the same message: the user interface board and the relay board could not begin communicating. This applies to freestanding ranges with 790 model numbers, plus the Elite electric slide-in range, models 790.4131, 790.5256 and 790.4255.
Owner steps from the manual
Unplug the range or switch off its power for 30 seconds before restoring it. If F027 shows again, disconnect power and check the harness connections between the user interface control board and the relay control board. Reconnect anything loose and replace a damaged harness.
A recently changed board could be the wrong part. Use the model number of the range to confirm the part number.
If nothing was replaced earlier
With a good harness, replace the relay control board.
If F027 continues, replace the user interface control board.
Elite slide-in owners will see the user interface board called the oven user interface board.
F022 is a communication failure rather than a failed start.
