    Default Fan on kitchenaid KECD807XBL01 downdraft only run in low speed

    Model Number: KECD807XBL01

    My fan suddenly just run in low speed not enough air flow to draw out smoke n steam. Do I need a new switch or should I check other problem first. Thanks

    Try to locate your tech sheet and wiring diagram. It's probably taped to the bottom or side. Check your blower motor windings (the values will be on the tech sheet). Measure the output voltage from the control board to the blower motor. Unfortunately I don't have a wiring diagram for that machine so you'll need to to locate which wires on your wiring diagram.

    Sorry, I couldn't find the wiring diagram of the motor anywhere. Any other suggestions?

    I'll ask our tech sheet guru if can find one. It's either the blower motor or the speed switch. The speed switch is a four wire switch and without a wire diagram it's a coin toss.

    Cooktop power off and fan motor at room temperature. Disconnect the motor connector. High speed windings is black wire to white wire = 32.7 to 38.3Ω Medium speed windings is blue wire to white wire = 51.2Ω to 43.7Ω
