Question about Maytag MMV5186A Microwave Oven
Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)

Tips for a great answer:
Hello epinvegas - Try reprogramming the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and restart unit. If it proves to be ineffective, then it sounds like the microwave has a faulty magnetron, wiring failure or control board. Contact a professional to assist with the repairs.
