Samsung Microwave MG7980W Parts

• No heat

After dismounting the unit from its wall-hanging bracket, the most tedious part of the repair was removing over a dozen screws holding the cover in place from the top, bottom, and both sides. Fortunately, I had placed the unit on a bench that allowed me to slide the unit allowing access to the screws on the bottom edges of the unit. Always discharge the capacitor before continuing to work on the unit by discharging the capacitor by shorting the contact without the diode to ground. Access to the... Read more

• Won't start

I have a Jenn-Air microwave that didn't turn on and had no lights. It just stopped working completely. I unplugged the unit and had to remove the rear cover using a *security screw kit* that prevents people from opening the rear panel. Once opened, I removed the fuse and testing it with an OHM reader to determine that the fuse went bad. But I also had to determine why the fuse blew and noticed a sticky oily substance under the Capacitor. I used a rubber glove and needle nose pliers to... 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

• Exhaust fan not working
• shuts off after a few seconds

The manufacture did not crimp the connectors down all the way so that every time the capacitor discharged the connector would arc on the sensor. When I took the cover off and noticed the damage the plastic had already turned to ash. Replaced the cutoff sensor with the one advised to me by Appliance Parts Pros and everything works as it should. I also soldered the connection this time just to be sure. Read more
