Sorry, we couldn't find any existing installation instruction that matched.
the TCO is a temperature fuze on the side of the exhaust outlet. When the exhaust registers too high a heat temperature the fuze blows and stops the entire unit from working.
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.

All power out. No display, not operational
Remove microwave and set on flat surface. Remove all screws on top. Remove all screws around back edge holding top on. Finally remove the screws on botton holding top on and remove top. On left side on top, remove 6 screws holding black channel in place. Also remove 3 screws holding metal top in place. Now lift black channel up and unplug 2 wires on cutout. Replace cutout and reinstall everything in reverse order. Worst part is taking microwave down and reinstalling.

Lack of power to unit
This is the second time replacing this fuse, last time was exactly one year ago. The first time I replaced it, I removed the oven from the wall & disassembled a number of things to reach the culprit. This time I left the oven mounted & was able to access the 2 grille mounting screws on the top of the grille & remove it. Next comes the black plastic air deflector held by two screws & is mounted in front & on the right, it is shown on the parts list just above part #1434. After removing it, remove the two silver cover screws in the front, this cover also doesn't have a part # but is shown to the right of part #1410. At this point you can lift this cover enough to access the fuse which is on the left & held in place by one tiny screw through the clamp at the top, (careful not to drop it when removing). PS: Don't forget to cut the power to the microwave before starting!

after 3-4 minutes microwave display would blink and unit would just cut out.
This was the second time I've had to open up the microwave. 1st time display would blank out but system would continue to operate. Found solder connections on board to LED display were defective. Resoldered and unit was fine. This time I found the connection to the oven cavity temp cut-off was bad, plastic connection cover melted. When unit operated bottom lead and wire would heat up. Couldn't measure a Discernable distance so either wire or connector connection surface was not sufficient to carry the current. 1st replaced sensor still wire heated up. Replaced connector and there was no sign how heat from resistances.

Original part was fried
Had to remove microwave from the wall. Then disassemble entire top assembly to get to the part. Easy enough to replace after that. Then just reassemble and reinstall. About 2hrs. total

Oven shut down when TCO (thermostat) detected overheat. Once cutoff, it has to be replaced not reset.
The spacesaver is mounted over the stovetop. I removed the oven, then removed all the screws from the cover. Removed the cover and located the TCO and removed the wiring and the TCO. Ordered the part VIA internet and replaced it . It helps a little that I was Radar tec. and taught Electronics for 10 years and repaired lots of Microwaves. However anyone could do it just watch what you remove and replace in reverse order.

The oven has stopped heating at the degree it is set. Is there a part that can be purchased to remedy this?
For model number JVM1490BD003

Hello Lawrence, Thanks for your question. The diode is the most common cause for the heat malfunctioning but the line fuse may also be a problem. Only a licensed technician should test and install these parts, however. I hope this helps.

Micro wave and heating element stopped working. Fan will turn on where is this part located
For model number 36363679201 Kenmore microwave combo
PartSelect logo
Hi John, Thank you for your question. If your microwave has stopped heating, there are some parts that you will need to check to see which one is causing the issue. You will need to check the diode, the fuse and the microwave convection element thermistor. The temperature cut-out is not listed in the parts list for your microwave. The thermistor is located at the top of the microwave near the fan. Once you have determined the part you need, please feel free to call customer service. We are open 7 days a week and anyone will be happy to assist you. If you have any questions, please let us know. We look forward to hearing from you!

The convection part of my oven works, but the microwave won’t turn on. It sounds like it wants to start, but immediately stops. All other functions and displays work fine. Do you have any suggestions as to what the problem might be.
For model number SCA1001KSS02
