Parts for Broan QP142BL: Hood Assembly Parts

This replacement electrical switch restores reliable control of range hood functions. When the original switch wears out, sticks, or fails, installing a new switch brings back proper on/off response for the fan or light. What it does:

• Controls hood functions—fan or light depending on the model
• Sends power to the motor or lamp when toggled to the selected position
• Common failure symptoms: no response, intermittent operation, or only working in one position
• Physical signs can include a loose/broken actuator or discoloration from internal arcing

• One switch

• Disconnect power at the breaker and verify no voltage before servicing
• Note wire locations; transfer leads one at a time to the new switch
• Ensure push-on terminals are fully seated; avoid bending switch tabs
• Test operation before reassembling the control panel

• Redirects exhaust air through the correct duct path to restore designed airflow.
• Helps prevent unwanted backflow or redirected exhaust that can cause poor venting.
• Can reduce abnormal noise from loose or broken airflow channels.
• Helpful when cracked, warped, or missing diverter pieces cause reduced performance.

• One diverter piece as shown.

• Disconnect power to the appliance before beginning any service.
• Remove exterior covers or duct connections as needed to access the diverter; keep fasteners organized.
• Verify the diverter seats securely and seals against mating surfaces; replace any damaged gaskets.
