Whirlpool Range Hood FAN Error: Fan motor failure
If you are dealing with a whirlpool range hood fan error, this guide will help you understand the cause and find the right solution quickly. What Does Range Hood Error Code FAN Mean? The FAN error code on Whirlpool WVW, WVU, GXW, and UXL series range hoods indicates a confirmed exhaust fan motor failure. The […]

Answer to continue safely
Is it safe to keep using?
No. The range hood cannot ventilate cooking fumes, grease, or steam. Using the cooktop directly below without functional ventilation creates fire and indoor air quality hazards.
Can I reset the code?
No. FAN is a conclusive failure code. The board will not allow normal operation and the code will return immediately after every power cycle until the motor is replaced.
When to stop immediately?
Stop if you notice: Stop all power-cycle attempts if you smell burning from the motor area — continued attempts risk board damage., Stop if the blower wheel is completely locked (will not turn by hand at all) — this is a confirmed seized-bearing failure..
Symptoms You May Notice
No airflow on any fan speed setting
The blower does not move any air regardless of which speed button is selected — ventilation is completely absent with FAN displayed.
Fan motor is silent even at maximum speed
No motor hum, no startup click, and no air movement — the motor is electrically or mechanically unable to energize.
Blower wheel spins with almost no resistance when turned by hand
An unusually free-spinning wheel (where the motor offers virtually no magnetic drag) indicates the motor windings are open and no longer generating a back-EMF load.
FAN code returns immediately after every power cycle
Unlike intermittent motor faults, FAN reappears within seconds of each power-on attempt, confirming the board has detected a persistent, non-recoverable condition.
Possible Causes
Burned motor winding
Years of high-temperature operation in a grease-laden airstream can gradually degrade motor winding insulation until a winding opens or shorts internally.
Requires ProfessionalSeized motor bearings
Bearings that have lost lubrication seize solid, presenting a locked rotor to the control board, which immediately faults with the FAN code.
Requires ProfessionalFailed run capacitor (single-phase motors)
The capacitor that provides starting torque on single-phase motors can fail open, making the motor unable to self-start from rest.
DIY PossibleSafe Checks You Can Do
-
1
Perform a single power cycle
Turn off the circuit breaker for 60 seconds. Restore power and press the lowest speed fan button once. Observe whether FAN reappears immediately (confirmed motor failure) or after a delay (possible intermittent fault).
Do not attempt more than one power cycle if FAN returns immediately — repeated restart attempts with a seized motor can damage the control board.

2
Test blower wheel rotation by hand
With the hood powered OFF and unplugged, remove the grease filters and reach in to try to spin the blower wheel. Note whether it is completely free, difficult to turn, or completely locked.
A locked wheel points to seized bearings; a completely free wheel (with no magnetic resistance from the motor) points to an open winding — both confirm motor replacement is needed.

3
Inspect the motor for visible burn damage
With the unit unplugged, shine a flashlight into the blower cavity to look for blackening, warping, or a burning odor emanating from the motor body.
If you can see the motor capacitor (a small cylindrical component), check for swelling or leaking — a bulged capacitor is a DIY-replaceable part that can cause the FAN code.
When to Call a Professional
Contact a qualified technician if:
- FAN returns within 5 seconds of every power-on attempt regardless of which speed is selected.
- The motor body is visibly discolored, blackened, or emits a burned odor upon inspection.
