MW857 Microwave - Instructions

My repair went terrible as I was sent the wrong motor 2 times. My stove sat in the middle of my small kitchen for 2 weeks. Finally the 3rd was the correct one except I didn't have the right nut so I waited another day for that to be sent. Everything working good now, I just hope the bottom fan doesn't go out after this experience.

Removed splash Guard to replace light bulb, reinstalled splash Guard. Installed new support clip.

This is a 1988 vintage microwave oven. I'm very relieved to have parts still available. The stirrer drive belt tore. I suspect dry rot, as I did this exact repair back in 2005.You simply remove the cover, replace the belt [easy] on top, and replace the blown fuse. While the oven cover is off blow out all accumulated dust and wipe/clean al ... Read more l areas that have a build up of dirt/crud. I purchased this microwave oven in 1988 and is very dependable.

First off if you are repairing an appliance this old better have some super glue. Many of these parts are no longer available. If the latch breaks with the door closed you can clear the broken plastic latch and open the door with a straightened coat hanger through the handle into a hole on the door which will trigger the latch. Once th ... Read more e door is open there are two screws that hold the black plastic trim piece on the inside of the door. Remove them both (Phillips head). The piece will come off. The handle is held to the front of the door by two more Phillips head screws. One at the top and one at the bottom. The handle in the front will not yet come off. There is one more screw that can only be reached by separating the door parts so you can get the screwdriver in. Now the whole handle will come off. Orient the new handle "trigger" so the piston can go through the hole in the handle. Be sure to put the spring on so it goes between the trigger and the handle. Now put the handle back on the door being sure to put the piston through the hole in the handle. It is best to put that screw in the middle back in place first then the others at the top and bottom. Put the plastic trim piece back on the inside and your are done. For what it is worth the trigger that I got is brown and not black like the other trim. Really not much of an issue.

Pretty easy tear down and assembly once I removed it from cabinet (built in micro)

dismantled the door to be sure handle would fit. Had to drill extra holes to re-enforce broken frame parts to metal door components then re-assemble. Parts were very fragile and subject to twisting out of square upon reassmbly. New handle is solid and door closes securely,microwave works fine.

Disconnected power and removed Microwave housing cover, observed burned end plastic connector of wire connecting to the thermostat (or thermal overload sensor); slightly wiggle one of the 2 wires to the thermostat would cause microwave power to cut out (when plugged in power). When powered on, I would try to run it but power cuts out aft ... Read more er just a few seconds. Removed the 2 wires from the old thermostat, removed the 2 screws that fasten down the thermostat, replaced with new thermostat and reapplied the 2 screws; cut off burned part of wire and resolder to new wire connector; reconnect both wires to new thermostat and reinstall MW housing cover. MW works good as new again. Thank you PartSelect!

Removed 5 screws on microwave trim and three additional screws on cabinet. Pulled microware part way out to expose broken drive belt on top and replaced with new one.
