Kenmore Range Hood NO-FAN Error: Fan motor will not run
The kenmore range hood no-fan error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Range Hood Code NO-FAN Mean? NO-FAN is a behavioral symptom code used to describe the most common Kenmore range hood complaint: the blower fan […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. The range hood can be used for light cooking while the fan is inoperative, but smoking, frying, or high-heat cooking without extraction is a fire and air-quality hazard. Repair before using the hood for heavy cooking.
Can I reset the code?
No. NO-FAN is a mechanical or electrical component failure — not a software state. A breaker reset will not restore a failed switch or motor. The failed part must be replaced.
When to stop immediately?
Stop if you notice: Fan motor hums continuously without spinning — turn off immediately to prevent motor burnout, Burning smell or smoke comes from the motor housing during attempted operation.
Symptoms You May Notice
Fan does not spin when any speed button or switch is selected
Pressing the Low, Medium, or High button — or rotating the mechanical speed switch — produces no airflow and no motor sound, indicating the motor is not receiving power or has seized.
Motor hums but the blower wheel does not turn
An audible hum from the motor housing with no airflow points to seized motor bearings — the motor windings are energized but the shaft cannot rotate, and the motor will overheat if left in this state.
Hood light works but fan circuit is completely dead
When the hood light responds normally but the fan is silent at all speeds, the fan switch or the specific motor circuit has failed rather than a total power-supply issue to the hood.
Fan starts on High only and will not run on Low or Medium
The blower spins up when the highest speed is selected but produces no motion on lower settings, indicating the speed-selection contacts or the motor capacitor winding for the lower speeds has failed while the High circuit remains intact.
Possible Causes
Failed or corroded fan speed switch
The mechanical speed switch on the control panel uses metal contacts that wear out or corrode from cooking grease and steam over years of use. A failed switch sends no power to the motor regardless of the selected speed.
DIY PossibleBurned-out or seized fan motor
The blower motor bearings wear out over time, eventually seizing the shaft entirely. On older Kenmore 233-series models, the motor can sometimes be temporarily freed by adding a few drops of machine oil to the oil ports — but most modern sealed motors require full replacement.
DIY PossibleInoperative electronic control board (Elite models)
On Kenmore Elite range hoods with touchpad controls, a failed main control board can cut power to the fan motor circuit entirely while leaving the display or lights partially functional. Board failure requires professional diagnosis.
Requires ProfessionalSafe Checks You Can Do
-
1
Confirm the hood has power and check the circuit breaker
Verify the hood light turns on — if it does, the hood has power. If neither fan nor light works, check the dedicated circuit breaker for the range hood and reset it if tripped. Wait two minutes after the reset and test the fan again.
Kenmore range hoods share a dedicated 120 V circuit in most installations. A tripped breaker is the simplest fix and should always be ruled out first.

Attempt to manually spin the blower wheel
Turn the hood off at the breaker. Remove the grease filters to access the blower wheel inside the hood cavity. Try spinning the wheel by hand — it should rotate smoothly and freely. A stiff or seized wheel confirms bearing failure. If the wheel turns freely but the motor still does not start under power, the switch or control board is the more likely fault.
Some Kenmore 233-series fan motors have small oil ports on the motor housing. If visible, add 2–3 drops of light machine oil (3-in-1 or sewing machine oil) and wait 10 minutes before testing — this can free mildly stiff bearings.
When to Call a Professional
Contact a qualified technician if:
- Motor windings measure open circuit on a multimeter continuity test
- Fan switch tests as defective (no continuity when activated) but motor shaft also fails to turn freely — two faults require professional sequencing
- Kenmore Elite control board shows no output voltage to the fan motor terminal despite power at the board input
