Samsung’s page for the ME21DG6300MT reads Over-the-Range Microwave Fingerprint Resistant Wi-Fi | 2.1 cu.ft.: a 2.1 cu. ft. over-the-range microwave. Because the ME21DG6300MT hangs over a cooktop it does two jobs, and its parts list is longer than a countertop unit’s: a vent fan, a cooktop light, a grease filter and a heat sensor that starts the fan on its own sit alongside the magnetron, transformer, capacitor, diode and door switches.
Everything behind the cabinet of the ME21DG6300MT – the fuse, the door switches, the diode, the capacitor and the magnetron – is tested on site by a technician who discharges the high-voltage circuit first; owner checks stop at the outlet, the breaker, whether the door closes fully and whether the turntable is seated.
