oven wouldn't heat
1. remove microwave from wall
2. remove cover (many screws)
3. remove nuts holding magnetron in place (4)
4. remove magnetron (this is a pain due to the plastic molding used to direct cooling air through the magnetron
5. get new magnetron in place (this was even more fun to find the right angles to tilt to get the magnetron to fit
6. re-tighten the 4 nuts on the magentron
7. put the cover back on
8. put the unit back on the wall.

bonus repair: the display flickered while the magnetron was on (cooking ) prior to the magnetron dying. found a ribbon cable on the control board to the display with an aluminum foil shield that had peeled off (adhesive failure). re-installing the aluminum shield with packaging tape, and the display no longer flickers

Microwave runs with the door open
Remove microwave outer cover. Turn on side & locate the upper & lower door switches. Better to replace in pairs even if one is ok. Remove the wire harness to each switch. Then replace switch and re connect the wire harness. Re attach outer cover
and test to see if that solved the problem. If so then well done!!

Microwave would turn on and count down, but not heating and not rotate turntable. Pressing door up would occasionally start heat.
First I disconnected the power and opened the door. Then I removed the top screws holding the top vent louvers, then removed the screw at the top of the touch pad. The touch pad removes by sliding up slightly then tilting top out. I unscrewed two screws holding the door latch assembly. Press the tab to remove and replace switch. Reconnect wires, reseat latch mount by placing top bracket tab in place first, allign and secure with screws. Reseat touch pad by placing bottom tabs in first, tilt forward and press up to seat top tabs, secure with top screw. Secure vent louver screws, plug in and watch your microwave work again.

Everything seemed to work with the controls, but when you pressed start the light would come on and nothing else. The turntable and heating system would not function.
I unplugged it, removed the outer shell with torque bits and a screwdriver, drained the main capacitor, and began debugging the circuit with my fluke multimeter, found the bad primary interlock, googled the part number, ordered the part, received it in 2 days, replaced the interlock in about 2 minutes, and put the cover back on. Fixed. Saved me about $200 over buying a new unit and was grateful for partselect's great service.

had to press door opener slightly to work
Removed screws holding outer shell. Pushed in door handle to identify faulty switch. Ordered part. Pryed switch out with screw driver and unplugged. reinstalled new switch. Presto. BUT... I did NOT use both hands while working on the microwave. I did not release the energy from the capacitor or whatever holds the killer amperage even when unplugged. It would be advisable to do this first. I did not because it seemed complicated, so I was EXTREMELY CAREFUL about not touching anything else inside the unit. I used one hand only so if I did touch something I would not get juiced through the chest. It was a piece of cake repair, but I would not go deeper without doing the discharge routine.

No cooking Power
Had to remove outer cover (special screws involved). Found the correct part at PartSelect.Com and it arrived 3 days later as promissed.

This oven has diffcult electrical connections at switch to get disconnected. I found it easier with the sw loose and in hand so that the connectors can be released with a small screwdriver.

One has to this in order to test the part wirh an ohm meter. I found the sw did not close but remained open and thus caused the oven not to function.

Removing interconnect switch is tricky but not difficult.

Outer cover replacement is not as easy as it should be, especially the sides.

All is well and working.

Microwaves are simple devices if you are know how to read and understand schemetic diagrams.

The glass tray that I got from Partselect cracked after a few months of use.
The glass tray in my microwave oven cracked and I found PartSelect on line. They sent me a replacement tray quickly. All I had to do was remove the cracked tray and insert the new one. Unfortunately ,after a few months this tray also cracked! I checked the Partselect website and found out my tray was guaranteed for one year ! PartSelect sent me a new tray free of charge. I received the tray in a few days.
Thanks Partselect!

microwave would not heat
First remove all screws holding on outer metal casing of microwave. Next remove the back and bottom metal pieces. You will then be able to pull aside the outer casing so you can access the door switches. Check each switch with an ohm meter in both the open position and with the switch closed. If the ohm meter reads the same in both the open and closed position, the switch is bad. Check the top switch first. Replace switch and reassemble. Cheap fix for a costly microwave. Great customer service at Parts Select!

Opened door to get food put more food in closed door it wouldnt work
Everything worked on the display light inside worked but when you closed the door and set time it would start counting down but not heating nor would the turntable turn. Started reading troubleshooting chart and first thing I did was removed the cover and checked door switches and found primary door switch wasn't working so I ordered a new one installed it and it worked. Anyone doing this has to be very careful because of the stored energy in the capacitor is strong enough to kill.
My micro is only 2 years old so I was hoping it wasn't anything major.

CERAMIC FUSE BLEW WHILE HEATING VEGETABLES
I found an exploded view diagram of of my microwave model which was very helpful. You need only remove outside metal skin by removing 4 screws on either side and 4 more on the back. Remove 4 plastic hole plugs from the top mounting inserts. Gently pull sides out and lift up and back to remove outer skin. The fuse is located on the back right corner behind the control panel. You access from the side. The fuse is under the spreader bar. Lift fuse up gently to remove.

P.S. It was the MSP Capaciter and or the interlock switch, snap apart 21A (19) failure that actually caused the ceramic fuse to blow.
