KEHV309PSS00 KitchenAid Microwave Oven Combo - Instructions

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

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!!

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.

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

Set the new one inside the microwave

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.

I found some of the feedback posted on this site very helpful. Taking photos as I went along was also very helpful in remembering how to put it back together. There are several over-lapping pieces to the door and you have to be careful to put things back together in the correct order. Lining up the screw holes on the hinges with the door is also a little tricky.

Remove and replace oven door hinges. Disassembly of oven door unit required. Step by step instructions available on youtube.

Just put it in

Quickly

Removed the door from the oven. Undid all the parts above the inner glass door. Installed the inner glass and reassembled the door. Reinstalled oven door.

Fool proof.

With just the removal of a few screws I was able to replace the glass with the side benefit of cleaning the outter glass that had gotten dirty over the years with use. This is a simple project that all can complete.
