A whirlpool range hood fan not working is a common complaint with a short list of causes: a power or wiring problem, a failed speed switch or control, a seized or burned-out blower motor, or a capacitor that no longer starts the motor. On Whirlpool range hoods (WVU and UXT under-cabinet, WVW chimney models) the key diagnostic clue is whether the lights still work — if they do, power is reaching the hood and the problem is downstream in the fan circuit.
Why a Whirlpool range hood fan not working happens
If both the lights and the fan are dead, the issue is power: a tripped breaker, a wiring problem, or a failed main control. If the lights work but the fan does not, power is fine and the suspect is the speed switch, the blower motor, or the motor start capacitor. A motor can also seize from years of grease buildup, so it hums but will not spin. On models with push-button or electronic controls, a failed control switch can cut the fan while leaving the lights alone.
Steps to try yourself
- Test the lights. If they work, skip the breaker and focus on the fan circuit. If nothing works, check the breaker and the hood power connection.
- Cycle through every fan speed. No response on any speed points to the motor or main switch; response on some speeds points to a partly failed switch.
- With power OFF, check whether the blower wheel spins freely by hand. A wheel jammed with hardened grease can stop the motor — clean it.
- Listen on startup: a hum with no spin often means a failed start capacitor or a seized motor bearing.
- Make sure any removable filter is seated and not blocking the blower intake.
When to call a technician
If the motor is seized or burned out, or a capacitor or control switch has failed, replacement means working inside the hood housing with line-voltage wiring overhead — a job many owners prefer to hand off. You can schedule a Whirlpool range hood repair and an experienced technician will test the motor, capacitor, and switch. Our overview of Whirlpool range hood repair explains what the diagnosis covers. Repairs use genuine OEM parts and carry a 30-day labor warranty.
Reading the symptom on your range hood
The precise behavior points to the part. A motor that hums but will not spin is the classic sign of a failed start capacitor or a bearing seized by hardened grease — the motor is trying but cannot get moving. A fan that works on some speeds but not others points to the speed switch or control rather than the motor, since a dead motor would fail at every speed. A fan that runs but suddenly stops after a while, especially if it smells hot, can be a motor overheating because grease buildup is making it work too hard, and it may restart once cooled — a warning that the motor is on its way out. And a fan that is completely silent with the lights still working tells you power reaches the hood, so the break is in the fan circuit itself. Matching the symptom to the likely part before you call saves time and helps the technician arrive with the right component.
How to prevent fan failure
Grease is the enemy: clean or replace the filters regularly and wipe the blower wheel periodically so the motor is not fighting caked-on buildup, which is the single biggest cause of a stalled or burned-out hood motor. Running the hood at a sensible speed rather than always on maximum, and giving it a quick wipe-down a few times a year, also extends motor life noticeably.
