Kenmore Microwave 401.80089700 (40180089700, 401 80089700) Parts

Unplugged power cord. Removed the microwave from over the range. Removed vent and screws on of microwave, which allowed me to remove compartment containing sensor at upper left area of microwave. Removed clamp holding sensor. Removed and replaced sensor. Reversed process and reinstalled unit. Read more

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... Read more

• broken bulb

Our microwave is mounted over the range, and has dual lights underneath that light up the range. A while back in trying to replace burned out bulbs, one of the bulbs broke and in trying to remove the rest of the bulb from the socket, I accidentally destroyed the socket. We worked fine with the remaining bulb for a year or so, but it finally burned out. Unfortunately all of the replacement bulbs would only last 1-2 days before burning out again in the one socket. When I'd originally destroyed... Read more

Did a little research prior to opening the microwave up. Microwave has to be taken down for repair and then hung back on the wall after repair. Would recommend using 2 people for this job. Checked the 3 thermocouples, one at the top (normally closed) and two at the bottom (one is normally closed and one normally opened). All three checked good. Checked both fuses, found the fuse marked Main Fuse to be blown. Fuses blow because of a problem, did some digging. Prior to the microwave going out... Read more

Main Fuse did not open, only fuse for high voltage section was opened. Prior to the fuse blowing a louder than normal hum was heard from microwave for 1-2 seconds prior. Easy fix is the high voltage capacitor, so first checked the voltage across the capacitor terminals to ensure capacitor was discharged. Typically should be reasonably discharged within 30sec-1min assuming drain resistor is still in place. Removed the high voltage cap, and checked the capacitance and did not get a reading....

Removed microwave from the built in cabinet (probably the hardest part) and took off top cover (screws on side and back). Had previously blown the power fuse 2 times in this microwave, so I checked the fuse first using an ohmmeter. This time fuse was good. Traced the power wires around to top side of microwave and saw the overheat "therm" switch. I believe the therm is installed there as a safety feature to open the power circuit to the microwave in case something was to overheat for any... Read more

Found the hi voltage transformer burnt out due to just being tired, checked all other components and every thing checked out ok. I started my career in Appliance repair 55 years ago so I have a little knowledge of the workings. I use you guys because of you great prices and fast delivery service. Well continue to use your products in the future. Read more

I used a voltmeter to test continuity on parts. I found 2 thermostats burnt out. I replaced all of the thermostats and also changed a capacitor. It now works well! Read more

Ordered new switches and ordered new switch plate every thing came quick about two days took 5 minutes to fix works perfectly. Have ordered from this company before excellent products always have what you need to fix it yourself. Very fast shipping will order again good company Read more

The fan that cools the main unit had started making noise a few weeks ago, I tried cleaning and lubricating the bearings, but the fan would make noise when it heated up, then finally stopped. I replaced the fan, it was up and running within 20 minutes of receiving the parts. Read more
