Range Vent Hood Hums? Range Vent Hood Troubleshooting
Range Vent Hood Loud or Noisy? Range Vent Hood TroubleshootingUsually, when the blower motor hums but does not turn, it indicates that the motor shaft bearings are worn out. Some older, larger motors have oil spouts. If your motor has oil spouts, try adding oil to the motor bearings to get the fan to turn freely. If lubricating the motor bearings does not solve the problem, or if the motor can’t be lubricated, replace the exhaust fan motor.

One possibility is that something is caught in the blower wheel. It is also possible that the blower wheel is rubbing against the blower housing. To determine if the blower wheel is at fault, try spinning the blower fan by hand. If the blower wheel does not spin freely, check for the blower wheel for obstructions. In addition, ensure that the blower wheel is not rubbing against the blower housing. If the blower wheel is clear of obstructions, but it still doesn’t spin freely, replace the blower wheel and housing.

Ensure that the fan blade turns freely. If the fan does not turn freely, check to see if the fan blade is rubbing against the blower housing. Inspect the fan blade for damage. If the fan blade is damaged, replace it.
If you've determined the thermal fuse has not blown and the control is receiving power, then the touchpad is likely defective and will need to be replaced.
If you've determined the thermal fuse has not blown and the touchpad and control panel is receiving power, then the touchpad and control panel is likely defective and will need to be replaced.
If none of the touchpad buttons are working, then it's possible the range vent hood's control board is defective. However, control boards are often misdiagnosed—before replacing the control board, first check all of the more commonly defective parts.
If none of the touchpad buttons are working, then it's possible the range vent hood's main control board is defective. However, control boards are often misdiagnosed—before replacing the main control board, first check all of the more commonly defective parts.
If none of the touchpad buttons are working, then it's possible the range vent hood's control module is defective. However, control modules are often misdiagnosed—before replacing the module, first check all of the more commonly defective parts.
To determine if the switch is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
To determine if the push button switch is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
To determine if the switch is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
To determine if the switch kit is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace the switch kit.
To determine if the rocker switch is defective, use a multimeter to test the switch for continuity. If the rocker switch does not have continuity, replace it.
To determine if the rotary switch is defective, use a multimeter to test the switch for continuity. If the rotary switch does not have continuity, replace it.
To determine if the selector switch is defective, consult your vent hood’s wiring diagram and use a multimeter to test the switch for continuity. If the selector switch does not have continuity, replace it.
To determine if the switch is defective, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
Check the fan blade or blower wheel for any obstructions keeping the fan blade or blower wheel from turning freely. If you can remove the obstruction without breaking the fan blade or blower wheel, the vent should be functional. If the fan blade or blower wheel is damaged or extremely dirty you should replace it.
