Common range repair parts you may need
Replacing one of these range parts may fix your problem.
Fan Switch Replacement
When a fan switch is defective, the hood fan won't turn on, won't turn off or won't spin at the selected speed. The switch, mounted on the control panel, can be difficult to reach and diagnose in some range hoods. A Sears Home Services professional can inspect the switch and replace the switch if needed.
Light Switch Replacement
If the light switch is defective, it may not supply power to the lights when turned on, leaving the area beneath the hood in darkness. This issue becomes evident when replacing the bulb fails to resolve the lack of illumination. Additionally, a faulty light switch can sometimes impact the operation of the fan, causing it to malfunction or operate inconsistently. Positioned on the control panel of the range hood, diagnosing and accessing the light switch can pose challenges. For expert examination and repair of your range hood's malfunctioning switch, enlist the help of a Sears Home Services professional.
Electronic Control Board Replacement
When the electronic control board in a range hood malfunctions, it can lead to several operational failures, such as power loss or erratic behavior from the blower fan or lights. Additionally, it may prevent the hood from shutting off correctly. This control board serves as the primary controller for the hood, managing functions like fan speed regulation and lighting. A malfunctioning board can disrupt communication between different parts of the hood, resulting in issues. You might observe unusual noises like chattering or clicking, along with a burning smell. Given its potential impact on multiple components, it's advisable to have a Sears Home Services professional conduct diagnostic tests to determine if board replacement is necessary.

DIY repairs on the latest appliance models are becoming increasingly difficult.
