Error code F18
Appliance Range
Quick answer

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

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 defective lower oven temperature sensor on Elite 721 ranges, or an oven control board failure on glass touch and Elite slide-in ranges.

The F18 code is the lower oven’s counterpart to F1 on Elite 721 ranges, and a board code on other Kenmore ranges.

Elite 721-prefix electric range

F18 (also shown as F4 or F5) means a defective lower oven temperature sensor. The manual says to unplug the range and have the sensor’s resistance measured, with replacement if it is off. That measurement is technician work.

Glass touch and Elite slide-in ranges

On the glass touch freestanding electric range and the Elite slide-in gas or dual-fuel models (790.3263, 790.3264, 790.4260, 790.4261, 790.4275, 790.4276), F18 is a failure of the oven control board. Disconnect electrical power, wait 30 seconds and restore power. A code that returns means a replacement oven control board.

Related Kenmore range codes

  • F17 is a sister control board code.
  • F16 is the lower oven too-hot code.
  • F19 is a lower oven not heating.
