Question about Emerson MW8106W Microwave Oven

1 Answer

Emerson MW8106W Blew internal 20A fuse.

No evidence of power to microwave; i.e, no clock, light, etc. Found it had blown 20A internal fuse. Replace fuse and it immediatly blew again. How can I determine if it is the transformer, magnitron, or some other component.

    I will go through the procedure of testing the high-voltage capacitor. Thank you for the help.

    Did it blow as soon as you plugged the cord into the wall?

    Or did it blow when you pressed Start to begin cooking?

You almost certainly have a shorted high-voltage capacitor.

Emerson Microwave Model MW8119SB found blown fuse. Replaced fuse power came back punched in 10 sec started microwave and fuse blew again.


Chances are that either the diode or capacitor are shorted. Be very careful, the capacitor can store a charge and should be discharged first for safety. Hope that helps...

All of a sudden, no power, no lights, NOTHING!


if the microwave is on the same circuit as the refrigerator, it's possible that the micro was turned on just as the refer compressor kicked on. i've seen that situation pop a fuse in microwaves many times - make sure you get a ceramic slo-blo fuse

If fuse, door switches, and capacitor are good, the next potential problem area is the control board (behind the keypad). Look for evidence of burn markings on the board and back of keypad panel; you may need to unscrew it to pull it out and look. I discovered with the same issues you have posted my LG microwave had a burnt board. Replacement is around a hundred dollars so I will just go buy anorther microwave (not LG!).

Magnatron is suspect. Need to put a voltmeter on it and see if the input (primary) side to the high-voltage transformer (big heavy iron thing in there) is getting 120Vac. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing the magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
