What F045 / F046 (790-prefix Elite slide-in) Means
F045 and F046 on Kenmore Elite 790-prefix electric slide-in ranges report the cooling fan running too slowly or too quickly. That fan keeps the control electronics and the surrounding cabinetry within safe temperatures, particularly during self-clean.
Common Causes of F045 / F046 (790-prefix Elite slide-in)
- Cooling fan blades obstructed by debris
- A failed cooling fan motor
- A hall sensor on the fan misreporting its speed, or a relay board fault
🔧 One Safe Check You Can Try
With the range cool and switched off at the breaker, check whether the fan blades at the rear are obstructed; the chart names blocked blades as a cause and clearing them is the first published step.
⚠ Why You Shouldn't Go Further Than That
- A slide-in range has to be drawn out of its cabinet to reach the fan, which needs two people and care for the worktop.
- Running self-clean with a failed cooling fan lets heat reach cabinetry that was never designed for it.
- Replacing a fan when the hall sensor or relay board is misreporting solves nothing.
