Most common repairs needed to fix a range hood
Fan Switch Replacement
When the range hood fan is not working but the light is working, a bad fan switch may be causing the problem. The fan switch starts the fan motor and controls the fan speed. If the fan switch no longer activates the fan motor, an internal electrical contact may be broken. A service technician will check for continuity through the fan switch wire harness terminals to see whether the fan switch is allowing current to flow to the fan motor when you turn the fan switch on. The technician will replace the fan switch if it’s broken. Schedule range hood repair service if you suspect that the range hood fan switch is broken.
Fan Motor Replacement
If the fan is not working but the light is working on your range hood, a broken fan motor could be the cause of the problem. The fan motor spins the fan blade to draw air through the range hood vent and exhaust the air to the outside of your home. If the fan motor breaks or wears out, the motor won't turn the blade to exhaust air out of your kitchen. A service technician will check the resistance through the windings of the fan motor to determine whether the fan motor is bad. The technician will replace the range hood fan motor if it’s broken. Schedule range hood repair service if you think that the fan motor is bad.
PCB Replacement
If your range hood has electronic controls and the fan is not working even though the lights work, the PCB could be defective. This electronic control board gets input from the user interface control and operates the exhaust fan and cooktop lights in the range hood. When the PCB won’t send current to the fan after getting the signal from the user interface control, an internal electrical relay could be broken or the internal logic of the control board could be corrupted. Schedule range hood repair service when you suspect that a defective PCB is preventing the fan from working even though the lights work properly on your range hood.
