91141485993 Kenmore Microwave Oven Combo - Instructions

Turned out the issue was easily solved by replacing a single, inexpensive fuse.

First off, UNPLUG THE MICROWAVE.

The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the microwave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.

First, disconnect the power from the electrical box, not just turn off that oven. specially if you have a double oven. Just turn one off is not enough.

I removed the two screws that hold the element in place. I then pulled the element out slowly about 2 inches to expose the connectors, and then disconnected the two wires by holding the wire (female) connector by one plier and pull the element (male) connector out with another plier. Then, insert the new element connectors, and push the wire back into wall then fasten the element with 2 screws.

I had to remove the oven from the wall because the sensor plug connction is behind the unit. Two screws hold the sensor inside the oven and then I disconnected the lead and pulled the sensor out from the front. I installed the new sensor, tightened the two screws holding it in and connected the lead. Then reinstalled the oven into the wall. Overall, a very easy repair once you get the oven out.

After turning off the breaker to cut power to the oven, I opened the oven door and, using the PartSelect exploded diagram as a guide, I removed 3 screws from the underside of the control panel - I was then able to slide the panel up and out to remove it. Leaving all of the control wires (especially the ribbon) connected to control panel, I saw the fan assembly mounted to the rear of the control box.

I noted the position of the two attached wires - black on top (or left), white on bottom (or right). Using a nutdriver with an extension bar, I unscrewed 4 screws holding the assembly in place. I removed the old fan and installed the new fan in its place. It was necessary to bend the new fan's legs out a bit to get them to line up with the holes. I reconnected the wires as mentioned above, then reinstalled the control panel.

I tested the oven by turning the breaker back on and letting the oven heat up to 450 degrees. The fan turned on as expected. After the oven cooled off, I reinstalled the 3 screws to secure the control panel.

The old fuse is perfectly good. The new ones arrived within a day.

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.

First, I waste $65 by calling some "REPAIR" service. They showed at home and charge me that just to tell me
Second, I researched on the web and ordered a part, which was not the issue. I waste abnother $72
Third, I found Part-Select and got the right answer: the Diode was the problem. Ordered the part form Part-Select and it FIxed it !!!

Note: I did not buy a new microwave because this one is mounted on the wall and it will cost me +$800 just the lowest price.

1. turned off electricity -- unplugged the unit 2. removed 3 screws on top of top vent, removed vent screen then I located the little white cylindrical fuse and popped it out with a table knife. Then I popped in the new fuse. Replaced the vent screen and screws -- plugged in the appliance and it is working again.

I took the door off, removed the four phillips screws that held the wall oven in it's hole. All the 1/4" fasteners were on the face of the over but you have to pull the oven forward to remove the hinges.
Buying thes two hinges from G.E. would have cost $ 90.00 I paid $ 55.00 from Part Select and they arrived the NEXT DAY. I did not do rush shipping.

removed two phillips screws. Unplugged electrical connections replaced unit from PartSelect. They sent holder cover and new bulb (surprise). Great store with great directions.

Removed the oven door for easy acces to oven. Unscrewed (philips screwdriver) the screw holding temp sensor in place. Gently pulled the wiring until quick connector was located. Pushed down on locking level on quick connect while holding other end of wiring (so wiring would not fall back behind oven). Connected the new sensor and screwed back in place. Reinstalled oven door. Tested temperature settings by turning on oven and comparing with a separate oven thermometer.

Disconnect the Power to the Oven

1. Took out the baking racks
2. With a nut driver, removed the two machine screws holding the baking element.
3. Pulled the baking element out 3-4 inches and using pliers, removed the wires from the back of the broken element.
4. Reattached the wires to the new element and reversed process.

One hinge assembly wouldn't close all the way, so the door wouldn't close completely. Removed the door. Removed the screws holding the entire oven to the cabinet (6-8 screws) and pulled out the whole oven about 6 inches. Since it's big and heavy, I rested it on an old plastic milk crate.

The pulley inside one hinge assembly was broken. It's held in by two screws from the front, removed those, took out the old assembly, put in the new, put the screws back in, pushed the whole oven back into the cabinet, put the screws back in to hold it to the cabinet, and put the door back on.

Used the trouble shooting guide and wire diagram found inside the microwave (thanks GE). Found the HV capacitor and diode had shorted. Replaced the capacitor and diode........works like new.

This did not fix my problem. I've ordered a new microwave.
