F1331W - Instructions

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

remove outer cover of microwave, (special recessed star bit required) change bulb, unplug and remove 1 phillips screw.

I mistakenly thought I had to remove the microwave to get to the back, not so. I would have had access to what I needed to unscrew; but I have to admit the hassle of taking it down and putting it back equals having to work on it attached to the shelf-your call on how you do this. I unscrewed the front top to remove the vent piece that is across the top front of the microwave. This will reveal the control panel screw. (While you have the vent removed you might want to clean the vent and the exposed filter.) carefully lift and pull out control panel. I unplugged a piece as the wires were tied tight. It will not completely detach, so carefully tip it back from exposed insides. The fuse is not clear but white with silver ends so look in upper right for it. I popped it out and replaced it. Replugged the wired part to cover and carefully fit tabs in and slide down to secre. Replace screw, replace vent piece and secure screws on top of microwave. I plugged it in to test before putting it back above my stove.

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.

Note: also had to replace turntable. Removed top cover using secure driver set. Placed microwave on it's front, using a soft towel. Removed edge screws from bottom plate (leaving 4 screws in center attached to heavy transformer). Separated bottom plate from body of microwave (leaving transformer wires still attached) exposing Synchronous motor. Removed two screws holding motor and electrical plug. Swapped new motor in its place. Re-attached bottom plate with its screws. Placed microwave onto it normal position. Re-attached top cover with its secure screws. Installed new turntable inside.

Removed case,
Discharged HV capacitor and removed cooling fan.
Unscrewed ground end of HV diode and unplugged from HV capacitor.
Installed new diode by reversing the order. In my case, the problem was the magnetron was bad, so I replaced it as well.

Removed micro bottom - 5 screws. One screw on the motor and a clip. Reversed the sequence, turned it on and watched it turn.

I could just set the new whirly gig in the bottom hole of the micro and it worked. The new part was delivered in 24 hours of my order and hence fixed in 24 hours. Thanks so much Part Select

Remove 2 Philips Head screws on left side of microwave. Remove 3 Philips Head screws from bottom rear of microwave. Remove 4 security screws from back of microwave (holding the cover to frame). These are the security type tips that are like a Torx bit, but need to be hollow in middle to accommodate pin in center of screw. Then back plate of microwave with heavy transformer still attached slides up and away. The wires aren't long enough to allow it to rest flat on the bench, but weight is low so it's easy to hold it upright while removing the motor unit. Separate connector from motor (simple) Remove motor by unscrewing 1 phillips head screw and rotating counter-clockwise a tiny bit. Remove Motor. Reverse steps to re-assemble. Note that there are a series of tabs at the bottom of the back cover that fit into holes in the baseplate of microwave. It can be a little tricky to line them up with the weight of the transformer, but it's not too bad. Once lined up, it drops in nicely and all the various screw holes line up. The microwave is a bad cooker when the plate doesn't spin. This simple and inexpensive fix saved me from having to buy a whole new oven.

Initially we started looking to buy a replacement microwave to replace our 13+ year old built-in microwave. It was a real pain finding a replacement to fit the exact dimensions. So I thought I'd try to find an old KitchenAid microwave. However, I was pleasantly surprised when this site came up on my search. Their website allows me to input the problems and then it showed two possible parts that needed to be replaced. I emailed tech support and asked them which part I needed. They responded very quickly and said I needed to replace the magnetron. I watched a couple YouTube videos and then pulled my microwave apart. It was incredibly easy to pull the outer cover off. The magnetron had 5 screws that needed to be removed and one electrical plug. Took me maybe 10 min to complete the entire repair. It was one of the easiest repairs I've done and so thankful for this site They saved me a ton of money from not buying a new microwave and we now have our microwave working again. In hindsight, I wouldn't hesitate. I'd order the Part now and get it fixed.

well I unplugged the microwave one day prior to working on it. shock precaution smart way to do this job. very easy pullout the screws behind the unit pull off the outer casing. minor screws inside the unit you have to remove a couple things out of the way. unplug the magnetron and remove first gives you more room to work on the side panel to replace the micro switches. I only replaced one the bottom micro switch. only one bad, but since I was in there I clean the bulb and changed the magnetron any ways. I read other reviews and made my choice to do so. it works perfectly now. Thanks PartSelect for having parts.

Unplug the microwave. Remove the Philips head and safety Torx head screws along the bottom of the sides and rear of the microwave which hold the black cover on. Lift the cover up at the rear and slide it backwards to disengage the tabs on the front top. Remove the cover. Discharge the capacitor by shorting the terminals to each other and then ground. Do this with a well insulated object and be aware there may be a pop when you do this. Keep hands, etc. on the insulated part of the object (screwdriver handle, etc). There's a lot of stored energy in that capacitor. I'd advise first checking the diode to make sure its not bad. Replace it if it is. The Magnatron is held in with a couple of screws on the top and sides. Unplug the connector and remove the screws. Remove the Magnatron. Installation is the reverse of removal.

Removed some cosmetic panels. Removed the assembly with micro switches. Examined the faulty switch by checking the clicking action of switch. Two others were ok by this method. Replaced the switch with new one. Works fine so far. Thanks to web site and YouTube videos.

Turned the microwave on its side. (Recommend turning it on its top. i had to fish the wire connection back to the center after it dropped away from the motor.) There is a spot under the rotation motor where an access port was stamped in the tin but not cut out. Used the small side cutter to complete the cut where tin had been left between holes. I unplugged the wires, removed the old motor by removing one screw, and installed the new one by reusing the same screw. The motor must have a reduction gear inside the case. The motor coil tested good, about 128 ohms, but it acted like there was a stripped gear inside. I wasn't interested enough to try to open the motor and confirm.

Had to go to the garage and get a small sheet metal screw to close the new trap door.

The "new" motor had scratches on it, made me wonder if it was really new, but it works fine and will probably outlast me.

Access is via RT. SIDE Panel as you face microwave. There are three screws on the bottom right edge to loosen. After that the side panel slips down and off. the fuse is located in the rear near where the power cord comes in. It is the white ceramic tube 1/4" in dia. and 1-1/2" long. Pull it out like any fuse and replace with new one. Reassemble and you are done!
