Inspect the motor coupling to determine if it is broken. If the motor coupling … If the motor … The motor coupling will have to be removed by prying or breaking them off. Washers with a direct drive motor have a motor coupler instead of a belt. I ordered new motor couplings … Those tabs … The motor coupler consists of three plastic disks (or tri-stars) with interlocking tabs. The motor coupling connects the motor to the washer transmission. Power applied to a motor that won't rotate can be bad on the motor windings and capacitor. I have the tub all disconnected and - Answered by a verified Appliance Technician We use cookies to give you the … Note: The two plastic motor couplings (one on the drive motor and one on the gearcase) are pressed on at the factory. Push one of the new plastic motor couplings on the shaft of the drive motor… It is then switched out of circuit by the motor switch. The capacitor is only meant to be in circuit for just a second or two til the motor gets up to speed. I am trying to check the motor coupler on my Thin Twin Whirlpool washer unit. How to Check the Motor Coupler. The washer wasn't spinning during the spin cycle. I removed the motor and one of the motor couplings was broken. The motor coupling can also fail due to normal wear. I didn't check to see if it gyrated during the wash cycle. Installing the coupling 1. 5. If the washer is overloaded, the motor coupling will fail in order to protect both the motor and transmission.
