What F018 / F022 / F023 / F025 / F027 / F028 / F029 (790-prefix, four-digit) means

On a Kenmore range numbered 790., these four-digit codes belong to the Electrolux-built platform. F018 reports a failure of the relay board, the board that switches power to the oven elements. F022, F023, F025, F027, F028 and F029 report communication failures between the user interface board and the relay board or touch panel. The boards have stopped talking to each other. The oven may not heat, and the panel may lose its display or freeze.

Common causes of F018 / F022 / F023 / F025 / F027 / F028 / F029 (790-prefix, four-digit)

Relay board that switches the elements
Communication cable between the boards
User interface board and touch panel
A power reset clearing a one-time dropout

✓ One safe check you can try

1. Note the exact code, since F018 differs from the F02x codes. 2. Turn off anything cooking and let the range cool. 3. Turn the breaker off for 30 seconds and back on. 4. See whether the oven and panel start normally. 5. If a gas range shows any gas smell, leave the house and call the gas utility from outside.

! Why to stop there

Seven codes lead to a short list of boards and cables
We find out which side of the link has stopped answering
We test the connection before replacing a board, and quote in writing first

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Why so many codes for communication?

Each code names a different link or board pair that lost contact. The F02x group means two boards stopped communicating, and F018 means the relay board itself reported a failure.

Is the oven unsafe?

Usually it simply will not heat or respond properly. If it behaves oddly, switch it off at the breaker and let us inspect it before it is used again.

What would you like to hear from me?

Tell us the exact code, whether the display is blank or frozen, and whether the oven heats. Then we test the cable and boards, and the written price comes first.
