Dacor Range Hood FAN-FAIL Error: Blower motor not running
Dacor range hood fan-fail — essential information for Dacor appliance owners. This dacor range hood fan not working guide explains what this fault means for your Dacor appliance and how to respond safely. A fan failure on a Dacor range hood means the blower motor has stopped running or can no longer produce adequate airflow, […]

Answer to continue safely
Is it safe to keep using?
No. A non-functioning range hood fan does not provide ventilation. While the hood itself is not a fire hazard in this state, operating a cooktop or rangetop without functional ventilation allows grease vapor, smoke, and combustion byproducts to accumulate. Schedule repair promptly.
Can I reset the code?
Yes. If the motor stopped due to a thermal overload trip, allowing the hood to cool for 30 minutes and resetting the circuit breaker may restore temporary function. However, the underlying cause of the overload must be addressed.
When to stop immediately?
Stop if you notice: Stop using the range hood if the circuit breaker trips repeatedly — motor short circuit suspected., Do not operate high-heat or high-grease cooking without functional ventilation for extended periods..
Symptoms You May Notice
Fan switch activated but no airflow at the vent
Turning the fan to any speed produces little or no airflow at the hood opening. Cooking smoke and steam rise past the hood unimpeded. Holding a tissue near the hood intake confirms minimal suction.
No motor noise when fan is switched on
The motor is completely silent when any fan speed is selected. A healthy Dacor blower produces a clearly audible hum at low speed and a stronger turbine noise at high speed.
Fan runs for a few seconds then stops
The motor starts briefly but cuts out within 5–15 seconds. This pattern suggests a motor thermal protector tripping due to overheating from a seized bearing or restricted airflow.
Kitchen fills with smoke during cooking despite hood being on
The most practical symptom — smoke, steam, and cooking odors that the hood normally evacuates are building up in the kitchen even with the fan running at high speed.
Possible Causes
Failed blower motor
The centrifugal blower motor has seized or burned out due to bearing failure or winding damage. Motors on range hoods have a finite service life, typically 8–15 years depending on use frequency.
Requires ProfessionalGrease accumulation jamming the blower wheel
Heavy grease buildup on the blower wheel can unbalance it or restrict rotation to the point where the motor cannot spin it, triggering the thermal overload protector.
DIY PossibleFailed capacitor on the motor circuit
The run capacitor that provides starting torque to the blower motor can fail, leaving the motor unable to start or causing it to hum without turning.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the grease filters and blower wheel area
Remove and clean or replace the grease filters. With power off at the breaker, look into the blower housing (if accessible without major disassembly) for visible grease buildup on the blower wheel. If the wheel is coated in grease, careful cleaning with a degreaser may restore function if the motor itself is undamaged.
Grease filters should be cleaned every 1–3 months depending on cooking frequency. Heavily soiled filters restrict airflow and accelerate motor stress.

Test the fan at all speed settings
Switch the fan on at speed 1, then speed 2, then speed 3 (maximum). Note whether there is any airflow at any setting. If speed 3 produces faint airflow but speeds 1 and 2 do not, the motor speed controller may be at fault rather than the motor itself.
On the DHD series, the boost function (maximum CFM) can be used as a quick test for whether the motor is capable of running at all.

Check for power at the hood (circuit breaker)
Confirm the range hood circuit breaker is not tripped. A failed motor can draw excessive current on startup and trip the breaker, making it appear that the fan is simply not running. Reset a tripped breaker and test again — if it trips immediately, the motor has a short circuit.
Range hood circuits are typically 15A shared circuits. A repeated breaker trip indicates a motor winding short requiring motor replacement.
When to Call a Professional
Contact a qualified technician if:
- Motor does not spin even with blower wheel cleaned — motor or capacitor replacement required.
- Circuit breaker trips on fan startup — motor winding short requires motor replacement by a technician.
- Blower wheel is damaged or out of balance — wheel and motor replacement recommended.
