Jim December 13, 2014 for Model Number PVM1790SR1SS Micro wave is powered up but when door is closed and setting set like express cook or timed cook when start button is hit clock counts down. The microwave does not power up or table turn initially a door jiggle engaged it then that stopped as well would this be a switch of some sort for the door or the control panel ? THanks for any help.
1 Answer Jim, There are 3 door switches that allow the unit to operate. There is the Primary which is the lower switch, the monitor which is the middle and the secondary which is the top switch. The primary and secondary should read closed with the door closed and the monitor should read open with the door closed. If any do not read properly then they would need to be replaced. Read More...

(To remove the grille assembly: 1. Open the microwave oven door. 2. Remove the 2 Phillips-head screws from the top front of the oven cabinet. 3. Slide grille assembly to the left and pull out. The bottom of grille is held in place with 2 tabs.Note: The tabs must be inserted when replacing the grille.) 4. Remove the Phillips-head screw that attaches the control panel assembly to the oven. 5. Slide the control panel assembly up and out. Make note of the locations of the 7 wire connectors, 2 relay connectors, and then disconnect them. 6.
