How to replace a range hood fan switch

This DIY repair guide explains how to replace the fan switch in a range hood. The fan switch starts the fan motor and controls the fan speed. If the fan switch no longer activates the motor or controls the fan speed, replace the switch with the manufacturer-approved range hood part.

Follow these basic steps to replace the fan switch in common Kenmore, Broan, Whirlpool, KitchenAid, Frigidaire and Electrolux range hoods.

Instructions

1. Disconnect electrical power

Shut off the house circuit breaker to disconnect electrical power to the range hood.

2. Remove the filters and the bottom panel

Pull the latch tabs to release the air filters and pull both filters out of the range hood.

Remove the screws that secure the bottom panel to the range hood frame and pull the bottom panel out of the range hood.

Warning: Support the bottom panel with your hand when removing the final screw to prevent the bottom panel from falling on the cooktop.

3. Remove the fan switch

Disconnect the wires from the fan switch. Squeeze the locking tabs together on the fan switch and push the fan switch out of the front of the control panel.

Tip: Take a digital photo of the wire connections or note where each wire is connected to the existing fan switch.

4. Install the new fan switch

Push the new fan switch into the opening in the control panel and snap the new fan switch into place.

Reconnect the wires to the new fan switch.

5. Reassemble the range hood

Slide the bottom panel into place. Secure the bottom panel with the mounting screws.

Reinstall the air filters.

6. Restore the electrical power

Reset the house circuit breaker to restore electrical power to the range hood.
