Answer to continue safely
Is it safe to keep using?
No. A range hood with NO-PWR cannot be used for ventilation. Cooking without functional ventilation allows grease-laden steam to accumulate, increasing fire risk. Resolve the power fault before cooking at high heat or with oil.
Can I reset the code?
Yes. Resetting the circuit breaker resolves NO-PWR when a tripped breaker is the cause. If the breaker trips again immediately, there is a wiring fault or a failed component drawing excess current — do not reset again and call an electrician.
When to stop immediately?
Stop if you notice: The circuit breaker trips again immediately after being reset, You detect a burning smell near the range hood or electrical panel.
Symptoms You May Notice
Pressing any button produces absolutely no response
The control panel is completely unresponsive — no lights illuminate, no fan starts, and no audible feedback occurs when any button is pressed, indicating the unit has no usable power.
All lights are off with no visible standby indication
Even standby or indicator LEDs that normally glow when the hood is idle are completely dark, confirming the unit is receiving no power.
Fan does not spin even when directly commanded
Holding fan speed buttons or pressing the power button does not produce any fan movement at any speed setting, ruling out a control panel cosmetic issue.
Warm spots or uneven cooling
Certain areas inside the range hood feel noticeably warmer than others because air circulation is compromised without a functioning fan motor.
Possible Causes
Tripped circuit breaker or blown household fuse
The dedicated electrical circuit feeding the range hood has tripped at the breaker panel, cutting all power to the appliance.
DIY PossibleBlown internal thermal fuse
A thermal fuse inside the range hood has blown in response to an overtemperature event, permanently interrupting internal power until the fuse is replaced.
Requires ProfessionalFailed power supply board or burned wiring
The internal power supply PCB has failed, or a wiring harness connection inside the unit has burned or come loose, preventing power from reaching the control board and motors.
Requires ProfessionalSafe Checks You Can Do
-
1
Check the circuit breaker panel
Locate the breaker dedicated to the range hood or kitchen ventilation circuit. If it is tripped (in the middle or OFF position), switch it fully off, then firmly back to ON. Retry the hood.
-
2
Verify the power cord and outlet (plug-in models)
For units that plug into an outlet, confirm the plug is fully seated in the outlet. Test the outlet with a lamp or phone charger to confirm it is live. Try a different outlet if the existing one is dead.
-
3
Inspect for visible signs of electrical damage
With the unit unplugged or breaker off, look at the power cord (if accessible) for burn marks, fraying, or melting. Do not open the hood enclosure — contact a technician if the cord appears damaged.
When to Call a Professional
Contact a qualified technician if:
- Circuit breaker is confirmed ON and outlet is live, but the hood remains completely unresponsive
- Breaker trips immediately every time it is reset
- Burning smell or discolouration is present on the unit's housing or wiring
