Newish oven powers itself off intermittently

This oven works fine some of the time. The circuit is fine and other items work fine on the circuit. AFter about 3 seconds, the oven will often turn itself off just as if the power had been interrupted to the circuit. We tested the circuit and there are no opens and all outlets are OK.

Re: newish oven powers itself off intermittently

I would look into the thermal shoutdown thermistor inside the micro. It's also posible it may be a bad switch, when power starts, the switch start reacting, not common but I see this posible.

I hope this helps.

Microwave went totally dead while operating; there is power to the outlet.

If the control panel lights up intermittently, then you either have a loose connection somewhere near the panel, or a failing component on the circuit board itself.

Having touch-pad problems with my KitchenAid KHMS2056SSS-0 range hood microwave. It's an intermittent problem where the touchpad activates itself and activates menu items.. and beeps each time. Resetting...

Usually the top vent front panel is held in by two screws and or clips, Get those off and the bottom of this peace should un hook, unless there are screws there also. if you can get this far, the rest will be obvious.

Lg microwave oven trips circuit breaker

The magnetron probably has a partial short pulling more current than normal as it runs, the other two items that give trouble is the high voltage diode, "sometimes cracks" to the high voltage capacitor, "usually shorts"

I have a sharp microwave sometimes it works for 10 or 20 seconds and then stops with error ee2, other times it works fine. Today it did the same but stopped with error ee1!

This sounds like a keypad problem, sometimes a short developes in the keypad controller causing all kinds of intermittent problems, on the back is the microprocessor circuit board which controls vital areas of the microwave oven. The cost to repair will be high and consideration should given to looking at a replacement.

Power quite one day it lost power like curcuit broke there is power to the outlet

If there was a power outage, and then your microwave oven never came back on. Then it could be a possible fuse problem. If the circuit breaker had tripped, then after you turned off the cir. brkr. and turned it back on, then everything should've worked fine. Again, I would lean towards a blown fuse in your microwave. Now you're saying there's power to the outlet, and it still won't go on? Then my easy solution would be to plug it into another outlet, and try it again. Your problem could be that plug. After doing everything I just suggested, at any time did you get a digital readout on your time display in the upper right hand corner of the oven. Basically, is there any lights on at all when you're plugged into the wall. If not, then the problem is in the microwave itself! It could be just as simple as a blown fuse, but I would like you to try these other alternatives first. Feel free to contact me again if these don't work. Good Luck, and I hope I've helped you some. Let me know, Jim

Our GE Spacemaker Microwave (Model No. JVM1650) intermittently kicks off while heating and resets itself so that we have to reenter the time and date. Is this a Magnatron failure?

Saw something like this happen when a magnetron gasket was bad and Rf energy was interfering with the control board. Could also be a connection problem in the power circuit, acting like it was unplugged momentarily. Heavy draw from the High Voltage circuit when in cook mde. Eric

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

Microwave Sylvania type sm81001

Have you ever replaced the fuse with Higher Amps fuse. There is a circuit diagram inside the cover please refer to that and ensure that the rating is same.
