Answer to continue safely

Is it safe to keep using?

No. Without a working fan motor, the hood cannot ventilate cooking fumes. Do not use the range beneath without ventilation until the motor is repaired.

Can I reset the code?

Yes. A power cycle may temporarily clear F1 if the fault was a control lockout. If the motor is mechanically failed, F1 will return immediately.

When to stop immediately?

Stop if you notice: If F1 returns after a power cycle, do not attempt to override the fault., If you smell burning from the motor area, disconnect power at the breaker immediately..

Symptoms You May Notice

Fan completely silent at all speeds

Selecting any fan speed produces no airflow or motor sound — the blower does not spin.

F1 code on touch panel

The electronic display shows F1 with an audible alert when ventilation is activated.

Smoke and odors not cleared

Cooking smoke and steam linger near the range rather than being drawn up into the hood.

Hood feels warm near motor housing

The area above the blower housing is unusually warm, suggesting the motor tried to run and overheated.

Possible Causes

1

Burned-out blower motor

The motor windings have failed from heat exposure or extended use at high speed.

Requires Professional
2

Failed motor capacitor

The start or run capacitor that helps the motor turn has failed, preventing startup.

Requires Professional
3

Motor wiring break

The wiring harness between the control board and the motor has an open circuit.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Power cycle the hood

    Turn off the circuit breaker for the hood for 2 minutes, then restore power and test all fan speeds.

    A transient motor fault or control lockout can sometimes clear with a full power reset.

  2. 2

    Listen for motor hum

    Set the fan to high speed and listen closely for any hum or vibration from the blower housing.

    A hum with no spinning suggests a seized bearing or failed capacitor rather than a dead motor.

  3. 3

    Check for obstructions

    With power off, inspect the blower wheel through the filter opening for grease buildup or debris jamming rotation.

    Heavy grease accumulation on the blower wheel is a common cause of motor seizure.

    Tools required

When to Call a Professional

Contact a qualified technician if:

  • Motor winding resistance testing with a multimeter is required to confirm failure.
  • Blower motor replacement requires accessing the housing inside the hood canopy.
  • If the capacitor is at fault, it must be matched to the motor specifications before replacement.
