Kenmore Range Error Code F91: Meaning and Fix
Reading the range display
On a range or oven the fault appears on the clock or oven display, often with a beep. Press Cancel or Clear once to silence it, and write the code down first. Check the model-number prefix first: the same Kenmore code can mean different things depending on the manufacturer.
Kenmore is a private label, and the factory that built your unit decides which fault codes it shows. The first digits of a Kenmore model number (110, 417, 665, 795, 796 and so on) tell you whether Whirlpool, LG, Electrolux or Frigidaire made it. Check the model label on your unit before using any chart.
What causes F91
- A failed relay, triac or processor on the main control board
- A loose ribbon cable or connector between the user interface and the main board
- Burnt relay contacts
- Moisture, a power surge or corrosion damage on the electronics
How to fix it
- Disconnect power for at least five minutes to let the electronics reset, then restore power and see whether the code clears.
- Open the electronics enclosure and look for burn marks, swollen capacitors, water traces or loose connectors.
- Check relay area for scorching.
- Reseat every connector and ribbon cable on the control and display boards.
- Check the supply voltage at the outlet to rule out a brown-out or bad ground.
- If the code returns straight away, replace the control module using the exact part number from the model/serial tag.

Questions
What does error F91 mean on a Kenmore range?
A relay on the oven control board did not switch as commanded. Kenmore sells units built by several manufacturers, so the code table that applies depends on who made your model; use the model number to confirm.
Can I keep using my range while F91 is showing?
Possibly, if the machine still starts, but a failing board can misbehave at random, so plan a repair.
How do I clear F91, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
