It was apparent that the microwave door closing switch was not working properly (the only way to get it to work was to slam the door shut very hard). I removed the metal side panel to reveal the switch mechanism and noted that the "slide lever" was not sliding properly each time the door was closed. Since this mechanism involved an inexpensive slide lever and two electro-mechanical switches which were also not too expensive, I ordered all three parts before disassembling the mechanism. As it turns out, I did not need any of these parts. After replacing them, the problem persisted. Consequently, I directed my attention at the spring loaded mechanism in the door that controlled the tension on the door latch. I found that the latch tension was OK but there was more resistance in the movement of the latch on the affected side relative to the other side ( the door has two identical latches). I then removed the tension spring from the latch together with the latch axle. After cleaning the axle and reassembling, the latch still did not move without any resistance. The last step which turns out corrected the problem was very slightly spreading apart with the chain link spreader (or any other tool available) the two metal sides on either side of the latch which allowed the latch to move without resistance and respond with the full force generated by the tension spring when the door was closed, transmitting this force to the slide lever which then activated the sensitive switches turning off the oven light and allowing the microwave to start as designed. If I had know that the door latch was at fault and repaired it first, I would not have needed any parts and it would have taken about 15 minutes.
