Microwave displays E7; turntable may not rotate and unit may not heat.

Safety first: Unplug the microwave before handling internal parts.

Turntable checks:

• Remove the glass tray and roller ring. Clean both thoroughly and wipe the oven floor.
• Inspect the plastic coupler (the piece that fits into the bottom of the tray). Ensure it is not cracked or stripped and that it sits firmly on the motor shaft.
• With the tray removed, plug in the microwave and start a short cook cycle. Look through the window at the coupler: it should rotate smoothly. If it does not move or moves erratically, stop the unit and unplug it.

Motor replacement (advanced DIY):

• Remove the bottom cover (if accessible) to reach the turntable motor.
• Disconnect the motor wires and remove the mounting screws.
• Install a compatible Farberware turntable motor, reconnect wires, and reassemble.

If you cannot access the motor safely or the error persists after motor replacement, seek professional service.
