Check the data. If it should have a 20 amp fuse and it blows or trips a circuit breaker you probably have a faulty element. Try disconnecting each element in turn,
Confirm that the receptacle where the microwave is plugged in is not faulty by plugging something else in the recepticle and seeing if it works or if the fuse blows. Check the power cord of the microwave for broken, frayed wires. Also check the bulb socket for broken wires. It may or may not be worth the cost of repair, depending on the repair cost verses a new microwave. There are repair parts available.
If the microwave oven is the newer type [7years or less], the problem is most likely the magnetron or the inverter board, but if model is older check for a shorted high voltage capacitor.
The only thing I can think of is check to make sure all switches are aligned correctly otherwise you will keep tripping the breaker, I'am certain that one of your switches are not properly in position.
go to the qualified electricians on your place... but there is some helpful tips that can help you.. (1) for continued protection before starting. turn off the main circuit breaker. (2) unplug all the appliances or equipment installed... (3) check all the wall socket outlet... look for any damages on the wall socket... if the wall socket outlet have no signs of burned or wet marked, try to turn on the circuit breaker. check if the problem is solved.. (4) if the wall socket outlet have a signs of burned or wet marked.. just replace that w/ the same type of socket... check also the appliances that may caused the problem... the easiest way to know is to look at the socket plug itself... ty
Are you referring to tripping the breaker? The microwave runs on 110 volts, and if you are referring to a central HVAC unit, it runs on 220. No way the one could blow the other, unless you are referring to a window unit. If it is tripping the breaker, you could start by replacing the breaker (can buy at Home Depot or Lowes), and if it still continues to trip the breaker, then it is more than likely the capacitor.
In that case the outlet your using is pushing out too much electricity. Try calling your local electric company for help or a professional electric repair man.
Safety first, unplug your microwave from socket outlet.Needs to troubleshoots series of components using eliminating method to know which component(s) that causes breaker to trip off. It is obvious that a componet(s) "shorted out".Remove your fuse and replace it with resetable breaker tested.
Remove leads of the transformer output(secondary side). plug power cord run the microwave.If does not trip off the cct breaker change your transformer. do the same to capacitor lead, one after the other until you discover which component that shorted and cause your cct breaker to trip off.
