What F018 / F022 / F023 / F025 / F027 / F028 / F029 (790-prefix, four-digit) Means
F018 on four-digit 790-prefix Kenmore ranges reports the relay control board as failed, and the F02x family reports communication between the user interface board and either the relay board or the touch panel as broken or unable to start.
Common Causes of F018 / F022 / F023 / F025 / F027 / F028 / F029 (790-prefix, four-digit)
- A failed relay control board
- A harness between two control boards unseated or damaged
- A failed user interface control board
🔧 One Safe Check You Can Try
Disconnect power at the breaker for thirty seconds and restore it; the published route starts there and checks the wire harnesses next.
⚠ Why You Shouldn't Go Further Than That
- The relay board switches the oven elements and carries the full supply current, so the range is isolated before it is touched.
- On gas models, close the appliance gas valve before any panel work.
- Three boards and two harnesses means a guessed parts order is more likely wrong than right.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
