Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
I had two issues, 1). The oven blower was making a lot of noise when the oven was turned on. 2). The microwave turntable wasn't turning.
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 spring on the door broke for 3rd time
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 instructions on the website, the repair is easy.

Upper Oven Latch Not Functioning Properly
Originally ordered just the spring assuming that might be it and it was the cheapest way. However after getting in I found that the latch assembly had a broken 'tit' that is intended to hold the metal latch in place as it moves. Attempted to glue w/ epoxy but as i expected there was too much pressure to hold it in place. So....ordered the assembly.

TURN OFF BREAKER.....

1) Remove the two side rails by removing screw on the inside bottom of rails.
2) It helps to remove the door to get it out of your way but not required. To do this open door fully and insert two nails or similar into holes on each hinge. Close the door until the hinge contact nails. Lift the door up and out.
3) remove the top control panel by removing screw on either side (outside of oven)and screws on the underside of panel behind upper door.
4) It help to completely remove the panel to have more room to work but not required. If you do it is a good idea to photo the cable locations so it is easy to recall where they go. For the most part they only fit one location but always a good idea.
5) remove the latch by removing all spade connectors and two screws in front.
6) place new latch and reassemble.

Broken spring in the microwave door
I followed the instructions that were posted for a do-it-yourself on the part. The instructions were spot on. One addition that I have to the online instructions is that I have a wall mounted microwave and had to remove the trim before starting the instructions. Additional instructions for wall mount are:

1. Remove one screw each side from inside the door to loosen the vertical trim.

2. Remove the vertical trim on each side.

3. Remove the 2 screws holding the bottom trim and remove the trim.

4, Follow the remaining instructions

I was trying to remove the oven door so I could clean the glass. Spills had run down between the layers of glass.
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.
