Unit was making rubbing, grinding noise. I shut off turntable but it still made the noise. Unit worked but didn't heat tea water as hot as usual. Finally the Unit shut down. No power at all. I checked the breaker not tripped. It's unplugged now.

You may also need to check the stirrer motor, part number PS3529203, to solve the noise and the heat issue. We hope this helps.

Vent Grille tabs snapped off
Repair was easy but you have to remove the screw at the top of the microwave (top left) in order to secure the far left tab with the hole in the tab. Place the grille in place, push to the left and then secure the screw you removed. Just remember that the mounted screw will need to be removed the next time you need access in order to replace the charcoal filter.

Magnitron failed
Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

Would not heat and made a buzzing or popping sound
Unplug the microwave. Remove the Philips head and safety Torx head screws along the bottom of the sides and rear of the microwave which hold the black cover on. Lift the cover up at the rear and slide it backwards to disengage the tabs on the front top. Remove the cover. Discharge the capacitor by shorting the terminals to each other and then ground. Do this with a well insulated object and be aware there may be a pop when you do this. Keep hands, etc. on the insulated part of the object (screwdriver handle, etc). There's a lot of stored energy in that capacitor. I'd advise first checking the diode to make sure its not bad. Replace it if it is. The Magnatron is held in with a couple of screws on the top and sides. Unplug the connector and remove the screws. Remove the Magnatron. Installation is the reverse of removal.
