MW81 Microwave - Instructions

I replaced all 3 door switches. Once you remove the top vent then remove the panel. Then remove the two screws holding the door switches in place and pop them out and replace them. It was tricky getting around all the wires but eventually was able to get around them. Took less than 20 mins to do and was less than $40 to fix. Much better t ...

Removed 4 small star head screws from back of microwave, lifted body off, removed blown fuse and replaced with new one (found where cord enters). This model is stainless inside and out and I like it a lot. It is also sold by Daewoo and a few other manufacturers.

Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides.

Read more control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.

Before ordering any parts I remembered seeing a fan above the nylon roof of the microwave. I had seen a belt that drove it on a prior repair 3 years ago.

I could also see the moter that turned the belt and tested it by starting and stopping the microwave and could see the motor pulley spin when it slowed to a stop. I then closed the control panel and screwed it in place.

That confirmed I proceded to go to the internet with the model # for the rane/microwave and looked for parts.

I had an easy job looking the part and saw that the fan as I had called it was named Stirrer because it kept stirring the microwaves over the food.

Overall I looked at 2 venders and chose Part Select because they showed the same catalog page and part numbers, and they had a better price.

I had my part/ belt in 4 working days and installed the new belt in about 15 minutes. This time unplugging the range so there was no power to be concerned with. It was a matter of picking out the old belt and putting the new belt on the motor then walking the belt over the large pulley at the Stirrer since the belt will stretch a bit.

Buttoned it up and later tested with popcorn and it left only a small amount of old maids.

Thanks, Walt
