Why does fuse keeps blowing within mircrowave


Hello friend, thanks for your post!

Based off the information you have provided I understand that your fuse blows every time your Electrolux microwave starts up. It sounds like it could be an issue within the control panel, capacitor, or circuit breaker. Because it could be a number of any one of several underlying causes, I would personally contact a professional to accurately diagnose your microwave to determine the root cause to reduce the risk of unnecessary parts-Matt

Microwave stopped working and was hot inside.


At just 13 months old I would be inclined to get in touch with Maytag. If you make enough fuss they will repair it under warranty. but just check that the air intake and exhaust are clear of debris first.

Hope this helps

Entered time, pushed start, nothing happened. Circuit breakers are o.k. Unit is only two years old.


If the oven is completely dead I would be looking at the internal monitor fuse, the most likely cause for this to blow is a poorly adjusted interlock switch.

Hope this helps

No power braker ok


There is an internal fuse on most microwaves, it will "Blow" if the door interlock switches are not happy, sometimes the fuse just blows, like some circuit breakers do.. get a few extra, replace it and see what happens..if it doesn't blow again, you're most likely ok, if not, there are more causes for the internal fuse to blow, beyond the interlocks, it's not going to be cheap.

JMC7000ADW Blows circuit breaker


I've had this problem twice with our microwave. The hint to where the problem lies is that the breaker blows when you open the door at times. Inside the microwave are three microswitches; primary and secondary interlock micro switches and an Interlock Monitor switch. The switches are supposed to shut down the microwave if it is running and the door is opened. But, I've found the upper primary switch can stick internal at times and when the door is opened the stuck switch will, because of the way it is wired as a safety switch, cause either the fuse or possibly the main circuit breaker for the oven to pop. The reason the stuck switch blows the breaker or fuse is when the door is opened the interlock switch will cause the neutral wire from the AC power to be applied to the Upper Primary Interlock switch which normally should be open when the door is opened, but if the switch is intermittent or the contacts weld themselves shut the neutral line is connected direct to the "hot" side of the power line through the fuse and thermostat. The first time my microwave failed the switch had melted the contacts together inside the switch and the second time the switch became intermittent and would blow the breaker to the over ever so often. I suspected the switch the second time this happened and utilizing an ohm meter I checked the switch several times by opening and closing the door and once in a while it would remain closed instead of opening when the door was opened. Of course while trouble shooting the power cord to the microwave must be disconnected and use all safety precautions when working around the high voltage areas inside the microwave. I wrote Jenn-Air about the bad switch and the way it is wired into the circuit, but never received any acknowledgement. I suspect these microswitches are under rated for the amount of current that passes through the switch, thus they overheat and eventually arc the contacts together. I hope this helps explain the intermittent problem and could explain many of the intermittent blown fuse problems I see in these internet help sessions

Home Circuit Breaker Pops When Door Is Opened


It does sound odd for it to blow the breaker. It should blow the fuse, not the breaker. But looking at the exploded view diagram, I don't even see a fuse! Makes me wonder if this is some foreign model. *grin* In any event, you will need to replace all the door switches since they all have been stressed by the same overcurrent. Also be sure that all the switch mount and door latch parts are activating properly when you open and close the door. The switches (generic replacements) are widely available from local appliance parts stores. If you need any other parts, you can see an exploded view and parts list here: http://www.geappliances.com/shop/prts/
