KEMC308HWH1 KitchenAid Microwave Oven Combo - Instructions

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.

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.

This was more difficult than anticipated - probably because I'd never done it before. Once I got the door off (I didn't have the proper pins and used nails but didn't realize they had to be headless) I found all the screws, which were relatively easy to take out. I was surprised that the thermal door glass was obscured by two other panes of glass. It took more disassembly than anticipated and a few false starts when reassembling, but all in all it got done. I was happy that a job that would have cost probably $300 or more ended up getting done for $40 plus my labor - which isn't worth much these days. I'd certaily do it again.

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!!

The oven is a KitchenAid convection oven with 4 panes of glass. The front, two inner glass panes that aren’t “touchable” and the interior glass that is the one that takes the heat from the oven and which you can clean easily - this is important because the descriptions of the glass all say “inner glass”. This is door #3 in the diagram that measure 10 x 22”. Which I cracked when I was pouring water into a pan to create steam for bread baking (lesson learned).

Because of the age of the oven, to remove the oven door it was necessary to place “pins” (we use medium screws) into the hole behind the door latches. Then were able to lift off the oven door. (We saw some videos on YouTube)

We placed the oven door on the counter top and removed ALL screws that held the door at the bottom and around the casing - KEEP these screws separate by where you’ve removed them so you replace them into the proper section when you reassemble the door. Each glass you remove has slots that hold them in their proper places. I recommend taking a picture BEFORE you take out each glass as there are brackets that need to go in proper order and you don’t want to forget the order.

We had to flip the door over in order to CAREFULLY remove the casing and access the different inner glass sections (took the opportunity to really clean them). Gathered the broken glass pieces into a paper bag and vacuumed the fragments. Then we were able to place the new interior glass from PartSelect, and reassemble the oven door. It’s perfect!

This took some time most likely because it’s a very old oven and you need to be methodical. I was just glad to be able to get the part - not yet ready to replace the oven.

BTW, originally I was guided to order glass #7 which is one of the inner glass panes that you cannot touch - unless you take apart the oven door - The exchange for the proper door was handled very quickly and easily. Hope this helps.

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

Set the new one inside the microwave

Followed a video. Followed instructions

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

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.

XLarge pizza tray in a 450 degree oven - slam the door & CRACK. Replacement glass arrived on Saturday - VERY FAST DELIVERY. Placed 2 allen wrenches in both hinges - open the door half way & lift up. Place the door on a towel. Removed 6 screws, lift & seperated the inner oven covering, removed the broken glass & cleaned inside & replaced with new glass. More time was spent cleaning & coming up with a tool to fit into the hinge

Removed old racks, installed new racks. Recycled old racks.

After reading all the other entries, I decided that I could do this! My first hurdle was getting the oven door off the hinges. Mine were not like any of the others described. My son-in-law looked at them and couldn't figure them out. So, I found the original installation instructions and, lo and behold, they said to flip the lever (one finger operation) in each of the rectangular holes holding the door onto the oven and then lift up until the door comes off. I did it, and it did! Boy, is it heavy! From there I just followed everyone else's instruction about undoing the screws, washing the glass panels, lining up the screw holes to get it back together, etc. One thing that took me longer was that the steel panel needs to go back the way it came out, not flipped! When I washed the glass panel it held, I put it down wrong and then "installed" it backwards. Luckily, I have a double oven and looked at the other one to see what was holding up the re-assembly! I'm glad that one of the others mentioned that the glass on the "bottom", the one that broke, isn't held in my screws or steel plates -- nothing, so I wasn't surprised when I got to it and it was "floating" on the insulation. My white insulation was like a fine fiberglass and was easy to stuff back in around the rim of the new glass. Took me a little over one hour. So, no more wet rags on hot glass (you'd think after living 72 years that I would remember this!) The glass fit perfectly and my husband would have been proud of me -- that I tackled a job that he usually handled, and that I saved over $200 for a couple of hours of labor and travel time.

This oven probably was manufactured in the '60s when the house was built. The door doesn't just pull off like the newer models. These pins fit into small holes on the oven hinges. I inserted the pins and lifted the door to a 45 degree angle, before pulling the door completely off. Now that turned out to be the easy part. I then proceeded to completely dismantle the door. It actually has 4 glass layers which had to be cleaned individually. The hardest part of all was actually remembering how to put it back together again. I put the door back on just as I had removed it, then took out the pins, and I was finally done! This was not an easy project, BUT the results look great.
