SOURCE: Hi I have a LG MG 583MC microwave,

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

If it's quieter than usual, it's probably a control issue, such as a bad door switch or mount, or a problem on the control circuit board.

If it's louder than usual or sounds the same, it's probably a fault in the high voltage section, such as the magnetron, transformer or diode.

Unless it is a convection type or is otherwise special, the average over the counter microwave is generally not economical to repair when high voltage parts or servicer help is needed.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
