ZSC2000FBB02 General Electric Microwave - Instructions

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!

Disassembled the front cover, found slow blow fuses, then replaced with microwave fuses 250V-20Amp. Utilized a few fuses to pin point the problem, Microwave functions all worked except the express feature, made an assumption after using a tester that it was the high voltage capacitor and the diode that attaches. Replaced both, plugged in and tested. Worked! reinstalled the unit. Sucessfull for the past month.

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.

Unscrewed the vent at top of microwave exposing small access to bulb. The access to this was very limited so that was the major issue in changing the bulb. You needed small hands to do the job.

I REMOVED THE TOP PANEL OF THE MICR0WAVE AND THEN REMOVED ONE SCREW TO REMOVE THE CONTROL PANEL. rEMOVED OLD SWITCH. SNAPPED IN NEW SWITCH AND CONNECTED WIRE. REPLACED CONTROL PANEL AND UPPER PANEL.

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.

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.

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.

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.

With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!

DISCONNECT THE POWER CORD and discharge the capacitor
Leave unplugged overnight
Remove vent grille by removing the 2 philips screws
Remove the LED panel by removing 1 phillips screw
Disconnect all connectors that plug into back of the LED board completely
Remove the wires from the switches (3) at the inside edge of the microwave door
Gently remove each switch housing and test all three switches for continuity
Carefully replace non-functioning switches and reassemble the panel
GOOD LUCK

Unscrewed the control panel (2 screws), lift up and let hang, with a plan screwdriver open bracket holding the switch, unplug 2 wires, replace with new switch, plug in the 2 wires, push switch back into bracket. Then slide on the control panel, put the 2 screws back. Easy fix.

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.

PER YOUR INSTRUCTION

Part just snapped into place and wires were reattached.
