KEMS377GBL1 KitchenAid Microwave Oven Combo - Instructions

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.

Gas Oven would not work without door shutting all the way. New hinges fixed the problem! Removing Superba oven door was the challege. Kitchenaid has their manuals available online which you can look up using the model # available on side of oven door. It contained instructions for door removal which required two pins (one in each hinge) inserted in the hinge holes for the door to release when you pull up and out on it. Nails may be used to replace the pins but the tricky part is removing the nails from the old hinges to remove them from slots in oven door. I used a 12 inch piece of small PVC pipe as a lever, inserting the pipe on the exposed portion of the hinge. This released the nails. The oven door must be taken apart which required removal of screws on the inside face, top and bottom of oven door. It went easily back together and the problem was solved.

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 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!!

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

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

Set the new one inside the microwave

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

Thanks to video provided by PartSelect the repair was fast and easy. My second experience with an appliance repair with parts and video from PartSelect. I am a happy customer.

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 almost 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.

Once we figured out to use small allen wrenches in the small holes of the hinge to enable us to lift the door off everything went smoothly. Took out six screws, lifted out the hinges - inserted new ones, replaced screws and replaced door. Yipee

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 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.

Thanks for the excellent service. Parts cheaper than local stores, arrived on time, with NO PROBLEMS.
Installation, probably 30-minutes. Took the opportunity to clean glass, door panels, etc while disassembled, so used about an hour. Oven cleaner was a big help in the cleanup.
Very rewarding project and it saves changing the unit and and refitting the countertop.

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.

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

Fool proof.
