When repairing this Samsung over-the-range microwave, Max Appliance Repair identified a malfunctioning magnetron assembly as the cause of the unresponsiveness and inability to heat food. We replaced the magnetron assembly with a new part directly from Samsung’s manufacturer to repair this Samsung over-the-range microwave successfully.

The magnetron assembly is a crucial component in microwaves that produces high-frequency radio waves that heat food. It consists of a magnet and two electrodes that generate radio waves. The assembly also contains additional components, such as a voltage regulator, filament transformer, and waveguide, which help control and direct the radio waves.
