Error code F8
Appliance Range
Quick answer

F8 on Kenmore Elite 721 electric ranges: what it means, the sensor test and the owner step.

Model compatibility

Kenmore reuses codes across series and model years, so F8 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

F8 is a defective upper oven temperature sensor.

Quick answer

F8 means a defective upper oven temperature sensor on Kenmore Elite electric ranges with model numbers beginning 721. The chart lists it together with F1 and F2.

Steps in the chart

  1. Unplug the range.
  2. Measure the resistance of the upper oven temperature sensor. The target is 1,090 ohms at 77 degrees F.
  3. A result more than 100 ohms away from the target means a new upper oven temperature sensor.

Step 1 is for owners; step 2 is what a technician checks.

Other codes to look at

Compare F9 (upper oven not heating) and F8E0 (cooling fan speed too slow).
