Three cavities in one stack is the job description of the MEDMCW31JS, and it shows in what can go wrong. At the top is a 1.5 cu. ft. microwave and convection oven with 7 modes. The middle is a 2.0 cu. ft. oven with 13 modes, from 3D hot air to Dehydrate and Proof. At the bottom sits a warming drawer. You normally find this in a kitchen where the microwave, oven and drawer were meant to share one column.
Each cavity is its own repair. A top-cavity microwave that runs but does not warm food involves the magnetron and high-voltage circuit, handled with care. A middle oven that is slow or cold involves the element, sensor and fan. The bottom warming drawer has its own heater and its own thermal protection.
With a stack this tall, one touch control manages all three, so we separate a control problem from a heating problem before ordering parts. Clean-cycle latch problems in the middle oven are common too. Quotes come in writing, and the work carries a 30-day workmanship warranty.
No. A running microwave that does not heat can mean a failed magnetron or diode, and some of those parts store charge. Stop using that cavity until we test it with the unit unplugged.
Yes. It has its own heater, thermostat and slide, so we can test and repair it without touching the ovens above, though we check the shared panel and supply on the same visit.
The control may be fine and a single cavity's relay or sensor may be failing. We test each cavity individually to see if the board is the issue before replacing it.
