KitchenAid Range Hood FAN-NOGO Error: Fan Motor Will Not Start
What Does KitchenAid Range Hood Error FAN-NOGO Mean? FAN-NOGO describes a condition where a KitchenAid range hood blower fails to start when switched on. Range hoods do not have a digital display like ovens or dishwashers, so the fault manifests as a behavioral symptom rather than a code on a screen. The motor may hum, […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Without functioning ventilation, cooking produces uncontrolled grease and smoke buildup in the kitchen. Use alternate ventilation if available until the hood is repaired.
Can I reset the code?
No. A power cycle does not repair a failed capacitor, seized bearing, or mechanical obstruction. Physical repair is required.
When to stop immediately?
Stop if you notice: Burning smell from the motor area, Hood continues to hum loudly when switched on without spinning.
Symptoms You May Notice
Fan control responds but no airflow produced
Pressing the fan speed buttons produces normal LED indication and control beeps, but no air is moving through the hood. No exhaust venting during cooking.
Humming sound from the blower area
A low hum is audible from the motor location when the fan is switched on, indicating the motor is receiving power but cannot start spinning.
Motor feels warm after a few seconds of operation
The motor housing warms up from locked-rotor current draw even though it is not spinning. This is a sign of a start capacitor or bearing fault.
Possible Causes
Failed motor start capacitor
The start capacitor provides the phase shift needed to start a single-phase induction motor. When it fails, the motor hums but cannot start. Start capacitor failure is the most common range hood motor issue.
Requires ProfessionalSeized motor bearing
Years of grease vapor exposure without adequate cleaning can cause the motor bearing to seize. Once seized, the motor cannot rotate even with a good start capacitor.
Requires ProfessionalFan blade jammed by debris or grease buildup
Heavy grease buildup on the fan blade, or a foreign object in the housing, can physically prevent the blade from rotating. Common on hoods that have gone years without thorough cleaning.
DIY PossibleSafe Checks You Can Do
-
1
Turn off the hood and inspect for obvious obstruction
Switch off the hood power at the wall switch or breaker. Remove the grease filters and look at the fan blade area from underneath. Check for obvious debris, heavy grease buildup, or anything jamming the blade rotation.
Never reach into the blade area with the power on. Always disconnect power before inspecting the blower compartment.

2
Clean grease buildup around the fan blade
If visible grease buildup is obstructing rotation, clean the blade and surrounding housing with a degreasing cleaner and warm water. Dry thoroughly before restoring power. Try the fan again.
Heavy long-term grease buildup may require scraping or soaking with a strong degreaser — patience is important to avoid damaging the blade balance.
When to Call a Professional
Contact a qualified technician if:
- Motor replacement required after start capacitor test failed
- Seized bearing confirmed by attempting manual rotation
- Heavy grease contamination requiring full disassembly
