Duane August 02, 2012 for Model Number 72180829500 Tried to use the auto defrost and no response it wouldnt work. I then tried cook and it was just fine. Then a breaker flipped and the kitchen lost power so I went and flipped the breaker all power in the kitchen is back except the microwave and there is ablolutley no power no clock no nothing. when I plug in another appliance to that outlet all works. I wanted to check the fuse but I cant find it. where do I find this fuse? Any other suggestions of what may be going on would be nice also.
1 Answer Hello Duane. You need to remove the outer cover off the microwave to access and replace the fuse 3B74133K in the unit. Read More...
Kathy July 02, 2012 for Model Number lg lmv1314b I have a lg lmv1314b micowave. its bran new and I was useing the timer on it the other day and my breaker poped. I reset it and everthing came back on except my micowave. I tryed everyhthing to find out info on this unit but not much that is helping. I would like to know if there is more then one fuse and if so where at. I only found one it was good but replaced it just in case. still noughthing comes on.please help.
1 Answer Kathy, You may have a damaged AC line filter 2B72130F if the fuse is good and the unit is still dead. We wouldn't think the control board 6871W2S152A would be the issue, but it is a possibility. Good Luck and Thanks Read More...
Anthony February 29, 2012 for Model Number LG Model #LMV1680ST Microwave Our LG microwave made a loud vibration noise than stopped working. Changed the fuse and all of the control panel functions worked: clock/light/options, but when the power button was pushed, the microwave vibrated loudly again for a few seconds then went completely dead. Do you know what may be causing this, or if it is common problem with this model?
1 Answer Hello Anthony. Based on the information you provided, it sounds like the magnetron 2B71165R is bad and will need to be replaced in the unit. You will also want to replace the diode 6021W3B001R with the magnetron and the fuse 3B74133Q. Hope this helps. Read More...
Anthony February 25, 2012 for Model Number LG LMV1680ST Hello. How can you tell visually, if a fuse, AP4440371 (LG #3B74133N), is blown or still good. Since the fuse is frosted, with a black stripe around it, the element inside cannot be seen. Thank you.
1 Answer Hello Anthony. I'm sorry to say that the only way to check a ceramic fuse is with a tester or by passing voltage through it to a known good circuit so you can see the circuit operate. Hope this was useful! Read More...
Candy C. August 05, 2011 for Model Number 72163252301 Where is the fuse located? And how do I get to it?
1 Answer Hello Candy. You will need to remove the outer cover off the microwave to access and replace the fuse 3B74133Q. It is located in the control section, by the magnetron, inside a fuse holder. Hope this helps. Read More...
