DCS Range Hoods FAN-FAIL Error: Fan motor not running
The dcs range hoods error code fan-fail indicates Fan motor not running. This guide covers symptoms, diagnostic steps, and repair options. DCS Range Hood Fan Not Running When a DCS range hood fan stops working entirely, the first check is the simplest: the circuit breaker. A power surge or motor overload event may have tripped […]

Answer to continue safely
Is it safe to keep using?
No. A range hood with a non-functioning fan provides no ventilation. Cooking without active ventilation allows grease vapor and combustion byproducts to accumulate. Resolve the fan fault before continued cooking at the range.
Can I reset the code?
Yes. If the thermal overload cutout tripped due to grease buildup, cleaning the filters and allowing the hood to cool may reset the cutout and restore operation.
When to stop immediately?
Stop if you notice: Burning smell persists after the circuit breaker is reset, Breaker trips immediately each time it is reset with fan on.
Symptoms You May Notice
No airflow from hood at any speed setting
Selecting any fan speed produces no air movement from the hood — no sound, no airflow through the filters, and no exhaust from the duct.
Hood lights work but fan does not respond
The hood has power and the lights function normally, but fan controls produce no motor response at any speed.
Fan runs briefly then stops
The motor starts when a speed is selected but shuts off within 30–60 seconds, suggesting a thermal overload cutout is activating.
Burning smell when fan is switched on
A burning odor comes from the hood area when the fan control is activated, indicating the motor is trying to run but is seized or shorted.
Possible Causes
Tripped circuit breaker or blown fuse
A power surge or motor overload may have tripped the dedicated circuit breaker serving the hood, or blown an internal fuse in the hood wiring.
DIY PossibleGrease-saturated motor causing thermal cutout
Excessive grease accumulation on motor windings or in the blower wheel area causes the motor to overheat rapidly and triggers the thermal protection cutout.
DIY PossibleFailed blower motor requiring replacement
The motor's windings, bearings, or capacitor start circuit have failed internally and the unit must be replaced by a qualified technician.
Requires ProfessionalSafe Checks You Can Do
-
1
Check the circuit breaker
Go to your electrical panel and check the breaker dedicated to the range hood. If it has tripped to the middle position, switch it fully off then back on. Return to the hood and test all speed settings.
If the breaker trips again immediately when the fan is turned on, there is a short circuit or motor fault — do not reset it again. Contact a qualified technician.

2
Inspect and clean the grease filters
Remove the grease filters. If they are heavily saturated, grease may have migrated into the blower area. Clean or replace the filters, then allow the hood to cool for 30 minutes and test again.
If grease has reached the blower wheel itself, the wheel must be cleaned before the motor will run without overheating. This may require partial hood disassembly.
When to Call a Professional
Contact a qualified technician if:
- Fan does not start after breaker reset and filter cleaning
- Circuit breaker trips immediately on fan activation
- Burning smell indicates motor winding failure
