SOURCE: 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

I would expect it to be connected to the same electrical circuit as your convection oven so if there are no breakers that have tripped in your electric panel and the convection oven still works then their are 2 options.

1) The Microwave is connected via a Fused Spur (or possibly a Plug direct into a Socket) and Fuse has blown. This could be located somewhere behind the Microwave or in a cupboard to the side or above.

2) The Internal Fuse on the Microwave has blown possibly due to a power surge or an internal component that's failed.

First thing to do would be to check for the Fused Spur or Socket located somewhere around the Microwave. If you can't find one then you would need to remove the Microwave and see where/how it's power supply is connected.

If you could look at this and then let me know your findings we can take the investigation from their.

My jmc7000 jenn-air blew a circuit breaker. No power to the unit. There is power to the recepticle. I'm wondering if it blew a circuit breaker, does that mean the problem is most likely a big problem...


Yau say a few conflicting things. First you wonder if it blew a breaker, and then say you have power to the receptacle. If you have poer to your receptacle your breaker if not tripped. There are NO breakers Inside of the Microwave. Only 1 time fuses. So, if your init is dead it has probably blown a fuse inside of the unit. If that is the case. Probably shorted HIgh volt capacitor would be my first guess. If it is jsut dead. it can be other things than just a blown fuse. bad thermal protectors, bad low voltage transformer on main circuit board. Burnt wires. Anything that will cause it to lose power inside the unit. From bad parts to bad connections.
