That hum usually indicates a bad magnetron WB26X23320. If the magnetron failed due to a damaged wave guide or damaged the wave guide when it failed then the appliance is non-repairable since that wave guide isn’t serviceable.
The magnetron also may have damaged or been damaged by other high voltage components.
