KEMC377 KitchenAid Microwave Oven Combo - Instructions

Removed all terminals and block mounting screws. Repaired one burnt terminal and reassembled. Replacement part was an exact fit and reassembly whnet very well.

The replacement turntable we received was an exact duplicate of the original. It was as easy as rinsing the new turntable, taking the old turntable out and putting the new one in.

My husband took the back off and replaced it. The repairman suggested pulling the range out into the floor to run the self clean mode. I have owned several such ranges and have never had to do that and won't now. Easy Clean Oven Cleaner will be the next thing I use.

cut power off and placed sturdy table same height as bottom of oven in front of oven. removed trim screws. pulled oven out onto table. removed top cover and panel on left side . tested transformer to be sure it was bad. then replaced transforner

The replacement of the blower was an easy repair. Just had to remove two back panels of the oven and the blower was then very accessable. Just remove the two electrical wires and then three screws and the blower came right off. Put the new blower on with the three screws and replaced the 10 or 12 screws holding the back panels and the job ... Read more was complete!. The difficult part of the job was removing the combo unit from the cabinet to access the back panels. That part took some effort. Had to build a platform to slide the oven out onto after I disconnected the electrical feed wire (#6 wire) located in a junction box in my attic. Once that was done, the actual blower replacement was simple. The turntable motor was a different story...Although replacing the turntable motor was going to be as easy as replacing the blower motor, I couldn't access the underside of the microwave without disassembling the whole combo unit cabinet! That was very disappointing to me that Whirlpool didn't make that part easier to access, so I didn't replace the turntable motor. Too bad but we are just going to live with the turntable not turning!!

Watched a U-Tube video that was helpful but did not address how fragile the plastic door frame was that the exterior glass front sat in / mounted to. The plastic door frame holes did not have metal inserts and plastic door holes were enlarged/stripped. Had to use larger screws. Also the plastic door frame was fragile and cracked in a coup ...

That said easy to install the two Torsion Springs.

Remove rear panel - remove sensor from inside - unplug from rear - reverse to install - did not fix problem

Ordered a new one, put it in place in less than one minute.

Disconnect the sensor harness and checked resistance on the sensor,should read around 1100 ohm I only got 25.The sensor is mounted in the oven cavity back wall below upper element,the door must be removed. Unscrew 2 Philips head screw,unhook the harness,install new sensor,reconnect harness,install screws.

Part arrived in timely manner and placed it in microwave oven.

Set the new one inside the microwave

I found that what was keeping the old temp sensor electrical connection attached to the stove-side connection was a little tab. It wasn't obvious that that was the thing that was keeping the connection secure but there weren't any other alternatives. So pushing the tab up with the metal probe (just a narrow rigid metal wire) allowed me ... Read more to pull the connection apart.

All this takes place way at the back of the oven so its difficult to fiddle with a screwdriver and the retaining screws at arms length. Putting a bit of scotch tape around the screw to keep it attached to the screwdriver kept it from falling off. My hand was a bit shaky extended like that so that was the way to go.

Bottom line, if your oven won't reach or hold the temp you dial in on the control panel it's the temperature sensor. Now if I set it for 300 deg. that's what I get.

Used the instructions I wrote up the last time. Printed them off, and still works like a charm.

This makes third time the spring has broken - last two times it has been the right side spring. Not the best designed microwave door. But at least with PartSelect having the part, and with PartSelect keeping my original instructio ... Read more ns on the website, the repair is easy.

My oven (late 90's/early 2000's model) didn't have the flip-down hinge locks shown in the video. It seems Whirlpool/Kitchenaid changed the hinges even though they didn't change the model number of the oven. With my style hinges, you have to put Allen wrenches or bent nails in the holes just behind the hinge pins. Then close the door al ... Read more most all the way and lift it out to separate the hinges. Spring force holds the nails in tightly until you replace the door. This video was very helpful:

Also, my door had 3 different kinds of sheet metal screws. Two of them have similar heads but different threads. Keep track of which is which for when you put everything back together.

1. Disconnect AC power 2. Remove back with several sheet metal screws. 3. Remove wires from Limit Thermostat. 4. Check Limit Thermostat continuity -- if open then Limit Thermostat is faulty. 5. Remove Limit Thermostat with two screws. 6. Install new thermostat
