Parts for Whirlpool YMT4070SKB0: 03 - Oven Cavity Parts

This microwave turntable motor mounts beneath the oven floor and spins the glass tray to help food heat evenly. Replacing a worn motor restores smooth, reliable rotation when the tray stalls, jerks, or makes unusual noises.

• Drives the turntable via the center coupler beneath the cavity floor
• Promotes even cooking by keeping the tray rotating during operation
• Common failure symptoms: tray not turning, intermittent/jerky movement, humming or grinding noise from below
• Helps correct stalling under normal load when the original motor is weak or seized

• Disconnect power at the breaker; microwaves contain high-voltage components that can retain a dangerous charge
• Typically accessed from the bottom of the microwave; remove the bottom cover to reach the motor
• Move wire connectors to the new motor in the same orientation and secure with original hardware
• Ensure the coupler and roller ring are properly seated; test rotation with a cup of water on the tray

Size: 4 x 8mm.
