Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Fan motor bearing wear, transformer vibration, loose mounting hardware, turntable motor resonance

How to Fix / Troubleshooting

Steps:

Determine if the noise is associated with the turntable by running the unit briefly with the tray and roller ring removed (with a safe load inside). If the noise disappears, the turntable components may be at fault.
Ensure the microwave is level and all feet are firmly on the counter.

If the squeal persists and seems to come from inside the cabinet, a motor or transformer may be wearing out. Internal diagnosis and replacement should be done by a technician.
