66463 Microwave - Instructions

I turned off the power to the oven at the breaker. I then removed the side trim pieces by removing the screws located behind the lower oven door. I removed the plastic trim pieces above and below the microwave oven and removed the control panel and slid it into the opening above the microwave. I located the two screws securing the microwave into the frame and began sliding it out. I had to disconnect a small wiring harness and two wires from the microwave that were attached inside the opening above the microwave. The microwave section was the easily slid out, turned on it's side where the turntable motor was accessed by removing the access panel. I pulled the old motor, checked resistance and it matched the new motor. I then checked the old motor by applying 120V to it and it ran FINE! I thought I had the wrong part, but decided to install the new motor anyway. I did, secured the access panel and replaced the microwave in the frame. I reconnected the wires and secured the control panel and tested the microwave...and the turntable works!

I decided the door switch was the problem because 2 problems happened at the same time. I removed the 4 screws for the top outside cover and the 1 screw that held the control board. After removing the control board screw, I lifted it up and removed it. This gave me access to the 3 door switches. I then removed the 2 screws that held the plastic piece that holds the switches. This made it easier then to replace the switches.

the burn thru was probably because stirrer motor was not turning, Unplug the microwave .freed the motor up bu manually turning. temporary fix. The cover is held up with small push pin clips. Just pry the cover off with a screw driver or other flat tool. Scrape offf the old silicone. There are two covers in the Kit. you just need 1. Remove the old clips for the roof of the microwave, put a bead of silicone on the new cover where the old was and secure the new cover with the push pins into the clips .

tested all 3 of the door switche for continuity, the top switch was faulty, replaced it,for approx $4.00 and saved a $350 dollar microwave.

I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?

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 the microwave from its mount above the stove. Remove the sheet metal top/sides piece. Pop the control panel loose to allow access from the front. Remove more screws that will allow the small inverter to be removed and the big inverter housing to be wrangled loose enough to remove the big inverter. Pop the inverter cooling fan from its mount. Disconnect wires and remove screws to remove big inverter. Install new inverter in reverse process.

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.

Open door and remove vent cover buy pulling gently. Next un plug the microwave. emove the screw at the top of the control panel. Slide the control panel straight up until the hooks on the sides slip out of the slots. Tip the panel toward you and unplug the three different plugs near the top of the panel. Now the panel will tip further out and it can be moved around to get the metal catch at the bottom to come out of the slot. This will let the panel tip down to a horizontal position making it easier to work on. Remove the one screw that holds the circuit board to the plastic rack. There are three tabs that hold it in place but all of mine were broken off. Next remove the three screws that hold the plastic rack and the screw that holds the grounding wire. Lift the circuit board up and slide the old plastic rask out. Don't forget to unplug the sensor light from the rack. Slide the new rack in place and snap the circuit board onto the new rack. Replace all screws, put the control panel back into the slot then put the hooks on the sides back into their slots, replace the screw at the top. Put the vent cover back on, plug it in and go have a beer.

Removed outer cover

removed lower door switch

installed new switch

Wa La!

Removed the MW from the wall. Took the top screws off the air vent. Then removed the two screws holding on the display. I then moved the display to its side and it revealed the micro switches. I removed the plug in leads from the micro switch one at a time. I did this with all three micro switches only one at a time. I reinstalled everything and plugged it in. No more fans starting when the door is opened.

Don't waste your time with other parts stores online. Partselect sells quality parts and they arrived 2 days early. I purchase a door switch from another online store and the switch was defective.

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.

I removed the broken tray and ring-turn and replaced it with the new
Service was fantastic, parts were ordered one day and received the next

Washed the glass tray and put in the microwave oven. Easy..
