Error code F18
Appliance Range
Quick answer

What F18 means on three kinds of Kenmore range and what the manual does about it.

Model compatibility

Kenmore reuses codes across series and model years, so F18 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 this code means

F18 is a lower oven temperature sensor fault on Elite 721 ranges and a control board failure on glass touch and Elite slide-in ranges.

Three ranges, two meanings

Range F18 means
Elite electric, 721-prefix Defective lower oven temperature sensor (the chart also lists F4 and F5 for this)
Glass touch freestanding electric Electronic oven control board failure
Elite slide-in gas or dual-fuel, 790.4276, 790.4275, 790.4261, 790.4260, 790.3264, 790.3263 Oven control board failure

What happens next

For the Elite 721 range, unplug it; a technician measures the lower oven temperature sensor and replaces it when the reading is off. For the board failures, remove power for 30 seconds, restore it, and watch for the code. If it comes back, the oven control board is replaced.
