Error codeF018
ApplianceRange
What F018 reports
Somewhere inside the range, the relay control board has quit working. You will see the code on 790 freestanding ranges and on the Elite slide-in models 790.4131, 790.4255 and 790.5256.
Remedy
Remove electrical power from the range.
Install a new relay control board.
Because the board is a technician replacement, switch the range off and arrange a visit rather than keep cooking on it.
Where else this board appears
F019: the interface board is unable to set up this relay board.
F010: an oven running away past 600 F, where a stuck relay on this board can be the cause.
Kenmore range service in San Francisco
Relay board replacement for a Kenmore range in San Francisco or elsewhere in the Bay Area starts with Kenmore range repair, reachable on (415) 825-6393. Give the code F018, the model number and whether the range has been disconnected from power.
Model compatibility: Kenmore reuses codes across series and model years, so F018 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
