Blows fuse when in combination mode

I'm a union Electrician so I completely understand the hazards of servicing the units. I recieved a JVM1190AY for free today and replaced the fuse whenI got it home and it worked fine when I put it on microwave for a like 2 mins. with a cup of water. I then put it on combination and started to clean up all the tools and I dont think they ever used convection cause the probe was brand new in bag unit is very clean too. I really don't know exactly how these guys work I know they cycle back and for is what im getting but I was watching it when I was passing and saw that a countdown time had begun. It counted down for a couple awhile then just shut down all power gone. I figured it wasn't the microwave part due to how long it was on. any help would be great cause i dont want to take it down it needs a 15 amp fuse correct?

First of all, I would direct you to our cirtical safety warnings available via our FixYa listing: http://tinyurl.com/yzjozk It may be a failing HV transformer or magnetron, or possibly a failing heating element. The online parts list shows the fuse as 15 amp. Inside the unit is an envelope which contains an informative tech sheet with a wiring diagram, troubleshooting information, etc. If that alone doesn't help you solve it, I would invite you to send us a scan or clean copy of that tech sheet, and we can guide you further.

My Magic Chef microwave oven blows fuse when i open door


If you're blowing fuses from opening the door that is the sign of a electrical short . You'll need to call a electrician to check it out. Changing the fuse in this unit can kill you. There's a capacitor that holds stored electrical energy that is dangerous. My good friend died from trying to change the fuse in his. Get a professional to check it.

My Neff microwave combination blows the internal 10amp fuse after about 5 secs.


Have someone look at the unit----shorted diode? Or bad inverter or MAGNETRON---10 amps means something serious is bad.

Yes there are fuses inside.
There are lethal voltages within Microwave ovens that can stay charged up for many days. If you do not understand the hazards, get it repaired by a qualified electrician.

My LG microwave went completely dead. I is only 3


under the outer cover,its either a 10-15-or 20 amp ceramic safety fuse avail at most hardware stores, the amp rating is on the side of the fuse, if the new one blows then either the H.V. diode/capacitor or the magnetron can be suspects

Not getting on. no lights


not much to go on here.. too brief But io will hazard a guess that the intenal fuse has blown.

Undoe the outer case and on the top of the unit there should be a ceramic fuse You will see that it has burnt. It can be replaced but you might find it blows again ( they are not cheap) You need to find why it blew. The magnatron may also be damaged and at that rate its cheaper to buy a new one than repair.
Check the fuse first

Fuse blows on microwave switch on


one of three things shorted could cause this: H.V. diode,capacitor,or the magnetron tube, take screw driver and short terminals on capacitor before touching anything inside the case, then chk resistance on capacitor should show infinite after needle settles, diode should show hi resistance one way and a lower resistance in the other direction(use the RX100 scale not the RX1) on both parts diode should not show very low resistance or it could be leaking,mag is a different story,it can be chk'd but in a different way

No power


You mentioned taking the "buttons" off. That may not give you complete access to the units motherboard or power supply area. Unplug the unit and remove the outside cover. Look for a blown fuse on the motherboard or power supply. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged.
