ZSC2000FBB - Instructions

The GE appliance technician replaced the magnetron, HV capacitor, and diode without luck but only charged me the service call, not for the rest. He however told me the only item left would be the HV transformer. Having watched the nearly 2 hour teardown and rebuild for the parts, it gave me the knowledge needed to attempt the HV Transformer. Having received the transformer, I tore into the micro removing the old TF. To my dismay, the old TF tested good (per advice from the internet checking the prim and sec resistance values... they also came close to the new TF. So I elected to dig out the schematic and troubleshooting flowchart hidden inside my micro. All things led back to a door switch which checked bad... part which I didn't have. Reassembled micro, ordered switch from Parts Select and installed in about 1/2 hour. Micro work great now. Only if the GE tech would have followed the flow-chart! I ended up returning the HV Transformer since it wasn't used and not needed. Had to absorb shipping costs.

DISCONNECT THE POWER CORD and discharge the capacitor

GOOD LUCK

Remove the ice bin.
Turn the ice maker selection to "OFF"
Use small flat blade screwdriver to open the plastic ears on the electic plug in connectiion
Use #2 Phillips screwdriver to remove the screw on the front left side of the ice maker
Pull the ice maker forward until free of the two studs in the left side rear of the freezer wall
Check to see if the supplied water chute is the correct size for your application, if not remove the water chute from the old ice maker and place it on the new one.
Place the new ice maker in the freezer connecting the slots on the left read with the studs on the left wall
NOTE; IF THE ICE MAKER DOES NOT APPEAR TO BE LEVEL HORIZONTALLY REMOVE IT AND CAREFULLY REINSTALL IT TO ACHIEVE LEVEL
NOTE: ENSURE THE WATER DELIVERY TUBE RESTS IN THE RECEIVER TRAY
Reconnect the electrical plug ( needle nose pliers may be helpful in aligning the male plug with the female plug)
Move the selector from "OFF" to "ON"
Replace the ice bin and close the freezer door

Unplugged power cord. Unscrewed six screws and removed bottom of microwave, unplugged wire from motor, unscrewed two screws holding motor, replaced with new motor. Put everything back in place, plugged it back in, and it worked good as new.

I went to LG website enter model number and was given a list of parts that need to be replaced with a percentage of which part fails the most. I order micro switch PS3522738 which arrived and PS3529293 was backordered. I installed the one that arrived. The microwave worked briefly. I reordered and waited for both switches to arrive and installed both. The microwave still doesn't work.

Unscrewed and dropped the bottom panel of the Advantium on its rear hinge, disconnected the light and the motor, removed the motor screws, and replaced the motor. Very simple.
However, not related to the Advantium or the motor, trim had been applied to the bottom of the wall cabinets after installation of the Advantium. This trim prevented the lowering of the panel (and future removal of the whole oven), so I had to chisel and file and repaint the trim to get it out of the way.

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.

Take cover off microwave. Check door switches to determine which one was faulty.Remove and replace faulty switch.

I replaced the TCO (fuze) through the vent opening after removing the vent cover and several small panels with a screw driver for visible access.. Some of the screws require a small offset screwdriver because of the limited access. I did not have to drop the unit from the wall over the range and was able to access through the vent opening to replace to failed TCO with a new one. The TCO is wired in-line with the power and other fuses to the unit and when it fails the enitire unit is cold with no power to lights or function of any kind. The GE service rep. said that the unit needed a new smart board but that was not the problem and they are no longer made for the older unit. I discovered the repair by looking at YouTube for repairs for the GE Advantium 120 microwave/convection combo unit.

Problem 1: cracked outer glass
1. Remove the outer glass assembly using the four screws along the top and lifting out/up, be very careful it doesn't fall off and break on the floor. Hold the handle while removing the last screw, it can fall easily.
2. Remove the handle using the 2 long screws on the back side which feed through 2 small metal plates that were previously holding the door onto the main cavity.
(3) If there is broken glass, it helps to remove the metal ledge the glass was on using the screws underneath and clean out all broken glass fragments, to do this you may have to remove the vent panel below it to get screwdriver access.
4. Assembling the new glass panel is the same steps backwards, should be obvious.

Problem 2: Light always stays on
1. Remove the door switch panel on the left side of the microwave, 1 screw.
2. Remove the right access panel on the right side of the microwave, this is large and has many screws, and a couple also need to be removed on top.
** Don't touch any wires when doing all this, and make sure you are grounded and don't produce an electrostatic shock. **
3. Manually toggle the door latch catchers on either side (just the plastic, don't touch any wires), at the same time, and see if the light turns off. If it does, the door latches might not be putting enough pressure, they may be cracked or need to be replaced.
4. Sometimes the switches get dislodged, for example if someone slammed the microwave shut. Try nudging the switch, or one of the connectors, slightly towards the door side, or tapping it from behind with a screwdriver. If it was loose you might get an audible click when it goes back into place.

Note: if the microwave light always stays on, it eventually might shut off after a long time. Power cycle the microwave before doing the tests above, so the light is on when you toggle the door latch switches.

Remove upper grill, then control panel, then 2 screws hold door switch mounting bracket, that will let you roll the switches out to work on them. Remove each switch by carefully pushing back retainer clips. Diode a long pair of needlenose pliers is helpful. The control board in front of capacitor comes out with a flat screwdriver and pry up. Removing grnd wires helps

unplugged power
removed main black cover.
located part WB24X10047 and replaced

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.
