Turntable does not work, motor and coupler are fine

I have a GE JVM1871SK microwave. I recently moved in and the turntable has not worked since I have been here. The coupler is intact and I tried replacement motor (both the old and new motor have continuity on a multimeter). The supply leads show 22V, but zero current when the microwave is in operation with the turntble function turned “on” in the control panel. All other features work (i.e. fans, lights, magnetron, etc.).
