Samsung DE47-20007B Microwave Thermostat OEM Part

I attempted to diagnose the four thermostats/thermal switches in the microwave....two right behind the control panel, one on top of the cooking cabin, and one under a metal shroud above the magnetron. While checking continuity with a voltmeter, i questioned one of them behind the control panel and the one above the magnetron. I then noticed a burn mark on the plastic connector sleeve for the one above the magnetron. I took a scrap piece of 14 gage copper wire and beat the ends flat with a hammer. I then removed the thermostat and connected the two wires leads by inserting the flattened wire into the connectors. I plugged the microwave in and controls were back up...lights were back up...and it heated a bowl of water. I found the thermostat on the provided parts diagram. Two days later, the part arrived and the microwave was back in service. Many told me to throw the oven away and get a new one. The oven was about 16mo olds and I didn't considered it to be a disposable gadget. Appreciate appliance parts pros for having the oven diagram and helping me find the right part....plus the quick standard delivery was a huge timesaver and reduced the about of whining I had to hear at home from the inconvenience of having to use an old countertop microwave. Oh how we've come to depend on our gadgets! I have about enough experience in electrical work to shock myself. I did read up on capicators and appreciate the awesome videos appliance parts pros provides to help troubleshoot these elements and prevent stubborn diy'ers from killing themselves. I will certainly recommend this website to others.

Unplugged unit, Tested all the thermostats after bleeding off any existing voltage. Found the thermostat at the top of microwave that rests against the ceiling of microwave had gotten a piece of food stuck to it and caused it to overheat. The contacts were melted. Cut wire, crimped on new leads, replaced thermostat and unit fired right back up. $5 fix. Took about 35-45 minutes to take microwave down, take off shroud and rewire and replace thermostat.

The Thermal fuse (Thermostat) had blown during normal operation, making the microwave inoperative. Replacing the thermostat solved the immediate problem, though why the fuse blew in the first place is unknown. This is a convection microwave oven and the interior normally bets pretty high. I think this is a design problem, and purchased several of these thermal fuses,

Replaced magnetron thermostat mounted directly over the magnetron (item 7-1 on drawing, Samsung PN DE47-20007B, AP Number AP4580109). Also replaced one of the electrical connectors to the thermostat (which had overheated) which a standard generic connector I had separately.

Replaced two thermal cutouts inside built-in microwave oven. The most difficult part of the repair was uninstalling/re-installing the built-in unit and removing/replacing all the screws for the cover. Additionally, tracing down the open TCOs was a trick without any diagram. The TCO on the top of the cavity was easy, but this is the first time I've seen a TCO mounted on top of the mag (partially hidden), so I missed it the first go round.
