Whirlpool DE67-00180A Microwave Turntable Motor Drive Coupler OEM Part

This was one of the easiest repairs ever. Five screws hold the bottom plate of the microwave in place. Undid those. One screw and a small tab hold the motor drive in place, making it easy to pull out. I broke off the old coupler. Removed the two wires from the motor drive, tossed the old motor, connected the new one, put it all back in place. The whole thing took maybe ten minutes.

The new one was the correct part so the fit was perfect. It works like new.
