Microwave no longer functional. Power and fuse check good.
1. Opened door to remove glass dish and plastic rotating wheel.
2. Turned breaker "off" to appliance at main electrical panel.
3. Removed two "star" screws located on side of front control panel.
4. Removed four screws (two top and bottom) from front bezel around the wall mount microwave unit.
5. With bezel removed; removed four screws (two top and bottom) from the frame seecuring the microwave above the conventional oven directly below.
6. Using an inverted laundry basket; slide the microwave unit out approx. 14-16 inches and balance the extended weight on the inverted laundry basket. I opened the oven door and placed the laundry basket on it.....was a good fit!
7. With the side sheet metal now exposed; remove four hex nut screws (black) from unit.
8. Also, swing front control panel open; notice two sheetmetal tabs securing side panel. bend each up to help release side panel.
9. NOTE: The sheet metal enclosure is a shield for the microwave unit. It interlocks around the side cover preventing accidental removal.
10. By removing the four hex screws, you will notice two philips screws toward the rear of the unit. Remove both of these screws and the side panel should come out exposing the magnatron.
11. Uplug the magnatron and light. The light is in a white plastic cover and the magnetron is the main device in the unit. There was a schematic in my unit that helps illustrate each of the locations.
12. NOTE: There are capacitors toward the lower rear of the unit that will remain charged although power is off. Safely dscharge these capacitors or don't service this unit on your own.
13. Remove the magnatron by removing the four philips screws attaching it to the side enclosure.
14. Remove the plastic cover encasing the light by removing three philips screws.
15. NOTE: The replacement magnetron does not include the thermal sensor secured to its case. You must remove this from the old unit or buy a new one. There are two small philips screws securing this in place.
16. Reverse order to install new units.
17. NOTE: there is a gasket on the magnetron (around the hole where the rotating head projects into the cooking chamber. Ensure gasket is properly installed to prevent microwave leakage.
18. Once everything is reinstalled; place glass of water in unit to test. Set controls properly and turn on. Water should be hot per setting.
