The MEDMC301WS combines two very different machines in one 29 3/4 inch opening: a 4.5 cu. ft. wall oven above and a 4.7 cu. ft. speed oven below that mixes microwave energy with convection. That makes it a favorite in kitchens where the microwave was moved off the countertop, and it is why a service call can turn into two separate diagnoses.
The upper oven is a conventional heating system with 16 modes, rotisserie and a meat probe. The lower oven runs the microwave, with its own high-voltage circuit, door interlocks and a magnetron, plus convection. Total draw is rated at 10200 watts on 240/208 volts, so the feed has to be sound.
If the lower oven turns on but does not warm food, we check the door switches and the microwave power path with proper safety discipline. For the upper oven we do the usual sensor and element tests. We quote in writing before ordering parts.
The microwave power path is the usual area: the magnetron, the high-voltage capacitor or diode, or a door interlock. These parts hold dangerous charge, so we test them with the oven unplugged and discharged.
Yes. The two ovens have separate heating and control circuits, so we can repair one without disturbing the other. We still check the shared supply and cooling fans on the same visit.
Metal and damaged dishes can cause arcing in the lower cavity. If you hear crackling or see sparks, stop using it and call us, since a scorched waveguide cover may need replacing.
