    Common range repair parts you may need

    Replacing one of these range parts may fix your problem.

    Thermal Switch Replacement

    If the thermal switch on a range hood malfunctions, it might fail to activate the blower fan as intended when high temperatures are detected above the cooktop, or it might not deactivate the fan when temperatures cool down. Diagnosing issues with a thermal switch in a range hood can be challenging due to its location and complexity. Therefore, it's advisable to have a Sears Home Services professional diagnose and repair any problems with the switch in your range hood.

    Fan Switch Replacement

    Mounted on the range hood control panel, the fan switch activates the blower fan motor at the selected speed. The fan switch may need replacing when the fan won't turn on, won't turn off or won't spin at the selected speed. It's difficult to reach and diagnose the fan switch in some range hoods, so having a repair technician perform the diagnosis may be required. The technician will be able to determine whether the fan switch needs to be replaced.

    Electronic Control Board Replacement

    When the electronic control board in a range hood is not functioning, it can result in various malfunctions, such as a loss of power or irregular behavior from the blower fan or lights. Additionally, it may prevent the hood from turning off as expected. This board acts as the central control hub for the range hood, overseeing functions like fan speed regulation and lighting. If the control board malfunctions, it can disrupt communication between different parts of the hood. You might notice unusual noises like chattering or clicking, along with a burning smell. Given the potential impact on multiple components, it's wise to have a Sears Home Services expert run diagnostic tests to determine if the board needs replacement.
