PVM1870DM3BB General Electric Microwave - Instructions

This microwave has two separate spring-loaded latch pawls. To get the broken latch pawl off and install the new one you first take off the rectangular plastic trim piece from the inside of the door to expose the pawls. There is a pin that secures the pawl in place. To get the pin out I had to carefully drill a regular hole bigger than the pin with the Dremel tool at the edge of the plastic door piece. I then could extract the pin with a small screwdriver or twizzers. The old pin and spring will come out and you reverse the procedure to install pawl and pin and connect spring. Then reinstall trim piece. I put a small piece of black electricians tape over the hole I made in the door edge. It doesn't show when door is closed and it blends well with the black plastic edge. Test to make sure microwave works and mine did after some carefully fitting of the trim piece.

There are five Philips screws on the bottom outside cover .one at each corner and one at the front center. Remove all four at the corners .leaving the front center for last. When the last screw is removed ,the cover will hinge down, it is attached to clips at the back that allow it fold down. The wire attached to the light socket is connected by a pull apart plug. Grasp at each end of the hard plastic connector and pull outward ,DO NOT PULL ON THE Wires ! Lift the cover from the back of the microwave place it on a flat surface on a towel keep it from sliding around. Remove the screws holding the porcelain sockets. Reverse procedure to reinstall .Installing new Halogen lamps is suggested. Use a clean tissue or cloth to handle the lamps, finger prints on the lamp will shorten the life .

Watched How to repair a Microwave that turns on when the door is opened Video on the web. From this took a shot at the switch was the problem. When I removed the switch it was defective. The small button was in and when you turned the switch upside down the button would drop back into position. Ordered a switch for $25.oo , installed it and the microwave is working fine.

At first I thought it was just the bulb, but I wasn't able to find a video of the exact model. The dificult part was figuring out how the vent housing came off (turns out it slid to the left then lifted out) but after I figured that out, replacing the cable assembly and the bulb was really easy.
