Removed the light cover screw with a Phillips screwdriver. Removed the lamps from the packaging just enough to free up the 2 prongs for fitting in the socket. Make sure the power is in the "off position". Install the bulbs one at a time by lining up the 2 sockets (Very important not to touch the halogen bulb glass surface while installing them). Energize the light switch to check operation of the new bulbs.

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.

Used Google to locate parts dealers for GE.
Ordered from Partselect.

Part arrived a few days later and I easily put it in.

I thought the cost of this part was out of line but all others sold it for about the same.

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

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.

Had to use a screw driver to remove the cover to replace the bulb. Worked great and your service was great. Probably didn't take more than 5 minutes.

Using a phillips screwdriver I opened the panel in which the two lamps are located and easily removed the lamps. I ordered them through the internet and was pleasantly surprised when I received them the next day.

Followed instructions that came with bulb I ordered and could not have been easier. Will use this site again.

Unfortunately the filter upgrade for my microwave was not a fit. When I tried it in my microwave my microwave did not work. I thought I was going to have to have a repairman come and check what was wrong. I decided to put the original filter back in and when I did my microwave worked fine. Select Parts Has issued me a refund for the purchase I made that did not work. I am at present still researching for a filter that work for my microwave.

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

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!

When removing a non-working door switch, you will see a hooked piece of plastic on the holder locker that looks like a latch. If you try to pull it back in order to either remove the bad switch or install a good one, it will likely break. Instead, you need to pivot the switch (It pivots on a little post which is fitted into a hole at the corner of the switch) out of position so that it is not held back by the 'latch'. Then lift the switch out. If you have to use lots of force anything, you're doing something wrong. Reverse all this when installing the new switch.

The first holder locker was shipped in a soft envelope and was damaged in shipping. I ordered a second holder locker with instructions to ship in a hard container and mentioned what happened to the first holder locker. The second holder locker was shipped also in a soft envelope and was received damaged.

I notified customer service and have yet to receive a response.

I now have the part on order with a local company.
