Question about Kenmore Microwave Ovens
Usually when you hear a pop during operation and it quits either the Power Diode or High Voltage Capacitor has failed. When they fail they usally also cause the internal 15 Amp fues to fail. The back comes off by removing the 4 screws (2 on each side) and 6 screws in the back. (UNPLUGGED!) The you slide the cabinet cover back about 1/2 inch.. lift the rear of the cover 30 deg and remove the cover by pulling to the rear of the unit.
Once inside take a bladed screwdriver and short across the capacitor at least 3 times just incase it was not the failure. If you don't do this and the Cap is good it can really ruin your day! Then isolate the Cap by removing the set of terminal connections tht includes the power diode connection. Use an analog meter on R x 10K and probe the cap terminals. You should see resistance then watch the resistance increase to infinity. Reverse the leads and watch for the same indication....resistance then increase to infinity. It should do this each time you reverse the leads. To check the diode you read both ways with the meter leads across the diode. One way will read ZERO ohms and the other way should read close to infinity. (You have to reverse the leads.) Like I said usually the Cap or the diode fails. Make sure you check the fuse for continuity also. Most of the time they fail when one of the 2 components above fail. DO NOT replace the fuse until you replace the failed part. Otherwise the fuse will fail again.
The fuse is located in the fuse block at the end of the power cord.
When your reinstall the cover make sure you ensure the front side locking tabs near the bottom front are engaged with the front of the internal chassis.
