On the covered Kenmore 790 and Elite 790 slide-in range 4-digit, F023 (Elite model 790 electric slide-in range with 4-digit codes) means Kenmore's service table lists this code as: communication failure between the oven user interface board and the touch control panel.
Differential
Likely causes of “Kenmore 790 and Elite 790 slide-in range 4-digit showing F023”, and how to tell them apart
- 1
A loose or damaged harness between the oven user interface board and the touch control panel
What separates it F023 shows on an Elite 790 and the panel stops responding
How to confirm Disconnect power and inspect the harness between panel and board
- 2
The touch control panel has failed
What separates it The harness passes but the communication failure remains after the power reset
How to confirm The Elite chart replaces the touch control panel first
- 3
The oven user interface control board has failed
What separates it A new touch control panel still gives F023 after it is fitted
How to confirm The chart replaces the board last, after the panel has been replaced

0 of 8 completedCorrect only the documented fault domain
ReversibleSwitch the range off, wait thirty seconds and switch it on again. A code that returns calls for a look at the harness between the oven user interface board and the touch control panel: push any loose connection home or replace a damaged harness. If the harness proves sound, the touch control panel is the next part, and the oven user interface control board comes last. Parts named: touch control panel, oven user interface control board.
Disconnect electrical power to the range, wait 30 seconds and restore power
ReversibleUse the range breaker so the panel and the board restart together, then run a normal bake cycle to test.
Check the wire harness connections between the oven user interface board and the touch control panel
Reversibleor replace a damaged harness before you consider replacing the panel or the board.
Replace the touch control panel, then the oven user interface control board if the problem continues
ReversibleThe Elite chart puts the touch control panel first for F023, and the oven user interface control board only after it.
Look at the panel for damage
ReversibleWith the range off, look at the glass touch panel for cracks, bubbling or a lifted edge. A damaged panel can lose its connection to the oven user interface board and set F023.
Reseat the ribbon between the panel and the board
ReversibleAfter disconnecting power, find the ribbon cable that runs from the touch control panel to the user interface board and press it fully into its socket, since a half-seated ribbon is a common cause.
Photograph the display and the keys
ReversibleTake a clear photo of the panel before and after the power reset, since a panel that responds to some keys but not others is a clue that the glass or its connector is at fault, and it helps a technician when you call.
Ask about the panel's availability
ReversibleThe touch control panel is a model-specific part, and the Elite 790 panel may need to be ordered. Ask the parts counter for a lead time before you plan a repair, so you can decide whether to wait or to replace the range.

Exact questions
Common questions
What does F023 (Elite model 790 electric slide-in range with 4-digit codes) mean on a Kenmore 790 and Elite 790 slide-in range 4-digit?+
Kenmore's service table lists this code as: communication failure between the oven user interface board and the touch control panel.
Which part does the chart replace first?+
The touch control panel.
Which parts does it name?+
The touch control panel and the oven user interface control board.
Can I keep using the cooktop?+
If the cooktop responds, you can use it with care, but avoid the oven until the control is repaired.
Is it worth repairing an Elite 790 with F023?+
A touch panel for a slide-in range is a mid-priced part, so if the range is otherwise sound, a repair is usually sensible. Ask for a quote with the model number.
Can the cooktop still be used?+
If the cooktop's own controls respond, you can use it, but avoid the oven until the panel is repaired, since the oven depends on the same user interface.
Could a spill cause F023?+
Yes, a spill that seeps under the glass can break the panel's connection, so wipe spills promptly and keep cleaner away from the edges.
How does F023 differ from the F022 code?+
They name different pairs of boards. F023 is the user interface board and the touch panel losing contact, which shows as a panel that stops responding, while F022 involves the relay board that switches the elements.
