Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
After closing door the display panel must be tapped on to keep the unit operating.
The switches are not the problem! The problem is in the tolerences of the latch housing. I have ordered two new housings (Upper & Lower) and will see if the tolerences are closer. If not I will try epoxying a shim to the plate that operates the microswitches. The other option is to file the mounting slots of the housing to allow adjustment, which would be iffy,keeping them from moving with use. The exploded drawings really need to be clarified. The scale is way too small. It was extremely difficult to pick out the individual parts of the mechanisiam.

Microwave made squealing noise when on. Fan was worn out.
This particular microwave is the over the range type, with an exhaust fan at the top and charcoal filters over the stove. Then to the side is the control panel for the microwave oven. You have to get into this to get to the fan. To do this, you have to take off the vent trim at the top of the microwave. Two screws. Open the front door and gently wiggle once the screws are out. Care must be taken with this because over time the channels that the screws go in can break, and then once that happens there's nothing to hold the vent into the oven. (I've replaced this once when both screw openings simply crumbled). Once it's off, there is a screw under it at the top of the control panel that needs to come out. There's another screw at the bottom of the control panel. Then, you slide the panel up about a half inch and then you can pull it out. After that, you can see the fan in there. There are two screws holding it in and a bunch of wires all around it. Pull out the multipin connector on the fan. There is a second plug-in wire that you may need to use pliers to get a grip on it. Pulling out a couple other nearby wire connectors will help loosen it all up so that you can move the wiring harness out of the way and tilt the fan out and remove it. Looking at the old fan, the bearings were tight and worn out, and that was the problem. It's not a particularly well made fan. Very simple open-frame motor with moving parts exposed, so it probably through the years ingested oil vapor from cooking, etc. Tilt the new fan into position, put the two screws back in and re-insert the wire connectors. Then all you need to do once all the wiring is neatly dressed again is put the panel back on, the two screws top and bottom, and lastly reinstalling the long vent at the top, (two long screws). Do that, and you're done. The microwave sounds fine now and works great.

Loud noise from inside microwave
I initally thought the problem was the turn table motor but after installing that motor & not being successful I realized the problem was the stirrer motor.Removing & insalling that motor was a bit more challenging but worth the effort as I saved either the cost of a repair technician or the puchase of a new one.The microwave is back in service & running fine.

Original filter needed replacement, bulb socket was damaged, lens was broken.
Removed the 7 screws holding the bottom of the microwave cover, also opened the access covers to the lights. Damaged socket was easily replaced along with both bulbs and the broken lens, then resecured the covers. Top front cover was removed (2 screws) and the new filter was inserted, then the cover replaced. Very easy, about 15 minutes, without any injuries!

No power to microwave
Had trouble isolating the problem, so I had a repairman identify the problem, then I ordered the part and replaced it myself.

Removed screws holding the grill in place. Removed air filter, removed screw holding plate under the filter in place. Reached in under fan cowling to find the thermostat cut-out. Disconnected the two wires. Put the new thermostat in place. Replaced screws plates and filter in reverse order.

Light Socket replacement
I was told by 2 different appliance technicians that the crumbled/melted light socket could not be replaced which meant replacing the entire microwave (expensive!). Other posters on your sight described the repair steps and I gave it a try. The hardest part was probably figuring out which switch in the fuse box belonged to it (now marked clearly). It was a simple matter of unscrewing the bottom panel of the microwave to access the socket, pulling the crumbled/melted unit off and shoving the new one on. I can't believe the repairmen didn't want any part of even giving it a try.

Microwave wouldn't start after "Start" pushed
Took cover off, noted the two side by side switches easily visible and we hought one of these was responsible. Then son noted a third switch at the top of the plastic assembly which inserts at an odd angle. When it was inspected signs of a previous short showed up with burnt contact points. Reinserted at same odd angle as there were guide holes, closed things up and oven worked 100%. Great prompt service and great website!! We will use you again
