Quick answer
F045 on a Kenmore range: cooling fan speed too low. Steps from the manual and when to call.
Model compatibility
Kenmore reuses codes across series and model years, so F045 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 thiscode means
Cooling fan speed too low.
F045: fan speed too low
On Kenmore Elite electric slide-in ranges (790.4131, 790.4255, 790.5256) this code says the cooling fan is turning too slowly.
Sequence in the owner’s manual
Cut electrical power to the range. Next, see whether anything blocks the fan blades and clear it; damaged blades mean a replacement fan. When the blades are unblocked and intact, inspect the harness that runs from the fan to the relay control board, reconnecting loose wires and repairing any that are broken. If those connections hold up, the fan itself is replaced, and if F045 continues, the relay control board is.
Compare
F046 reports a fan speed that is too high, and F031 reports an oven sensor probe failure.
