Wrong part WB21X10046
By the diagram I thought I ordered the sensor that measures the bottom of the microwave being overheated by the stove below. The needed sensor is a normally open switch mounted behind the control panel on the bottom of the microwave. (as shown on the diagram) The switch received is a normally closed switch that is mounted at the top and opposite end of the microwave. A different website listed the part as WB21X10045?

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 openi

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.

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 bla
... Read moreck 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

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

I just replaced part wb21x10148 thermal fuse because the microwave would not heat but it would run. Now with fuse replaced the vent fan runs on high when the unit is plugged in stating it senses high heat and will turn off automatically. Will replacing the thermostat resolve this issue?
For model number CSA1201RSS02
Hello John, Thank you for the question. I suggest testing the door switches. You can test the switches with a multi meter to check for continuity. Hope this helps, good luck with this repair!

One of the thermostats was toasted where the plastic around the terminal connector melted. Main Fuse is good still have lights and clock. Installed new N\C thermal fuse and Installed new control board but still no heat nor is the table turning.
For model number cvm1790ss2ss
Hello Joseph, thank you for writing. The issue may be the Diode Cable PS239148. The main heat source is generated by the PS12725839. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you.
One of the connections of the one thermostat PS3491479/WB20X10048 that is outside the magnetron has melted plastic/black heat damage to the plastic connector part of the wire. I'm definitely buying a replacement thermostat, what I'm wondering is if there is a corresponding plastic clip that can be crimped to the white wire that's damaged if I cut off the end part and recrimp it? (Trying to avoid buying a whole new wiring harness or taking apart the whole unit.)
For model number PT7800SH4SS
Hi Robert, thank you for contacting us. Unfortunately, the plastic clip is not sold separately, and you may need to purchase the complete wire harness, part number PS12722495, along with the thermostat, part number PS3491479. If you need help placing an order, customer service is open 7 days a week!
