    Most common repairs needed to fix a Broan range

    Thermal Switch Replacement

    When the thermal switch on a range hood is faulty, it may not turn the blower fan on as designed when high temperatures exist above the cooktop or it won’t shut off when temperatures above the cooktop cool down. Because a thermal switch in a range hood is difficult to reach and diagnose, it’s best to have a Sears Home Services professional diagnose and repair switch problems in your range hood.

    Fan Switch Replacement

    The fan switch is mounted on the range hood control panel. It 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. The fan switch can be difficult to reach and diagnose in some range hoods. Have a service technician diagnose and repair a fan problem in your range hood. The technician will be able to determine whether the fan switch needs to be replaced.

    Electronic Control Board Replacement

    An inoperative electronic control board can lead to various failures in a range hood, including a complete lack of power or erratic behavior from the blower fan or lights, or prevent the range hood from turning off. This is because the board serves as the brain of the range hood, controlling the operations such as regulating fan speed and lighting. If the electronic control board malfunctions, it can disrupt communication between different components. A failing board may cause a chattering or clicking noise from the hood and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.

However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

    Sears Home Services recommendations for a range hood that won't turn off

    When the range hood won't turn off it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of range failures.

    What to look out for with a range hood won't turn off diagnosis

    Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your range problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
