Boiling water in my GE Spacemaker Microwave it stopped working and looks as if it is at half power. When activated it makes a half power type noise and the light goes dim. Is this a fuse issue?


Probably not a house fuse. Typically good or bad!! Have you tried it in a totally different outlet?? Could be a bad connection of your circuit breaker to the bus bar in your circuit breaker panel. Try it on an outlet on a different breaker. Or have someone check the power at the outlet when it is running and see if the voltage is dropping.

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"

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.

GE Spacemaker Microwave JVM1441 BH04 tripping circuit breaker


your power transformer for the magnetron could have a shorted primary power winding,the door safety interlock switch could be mis-adjusted,this normally blows the internal unit fuse,a shorted high voltage capacitor,or diode,a bare wire inside the unit,more than the microwave on that circuit or a weak circuit breaker in the house power panel

Microwave trips circuit breaker when plugged in repeats when breaker is reset . There is no problem with house electric.


The circuit is probably a 20Amp circuit (see the number stamped on the circuit breaker switch). Most likely, it is the same circuit as the refrigerator, crock pot, window A/C unit, etc....

Also, if you are using an extension cord or a power strip or a surge protector. Those may not have a high enough power rating.

One other possibility (not likely) is that the circuit breaker is a 15Amp and the microwave is 1500 watts.

What else is cut off when the circuit breaker is tripped?

Solution is to use a different outlet for the microwave, or turn off any other applicance in the same circuit (except the refrigerator, of course).

Hope this helps!

My fridgidaire "FMV157GB" microwave has no power. is there a breaker?


HI, this is an unfortunate power board failuer. there has been a major burn out within the capacitor set and a diode as well. you will need to replace the power supply board in this unit asap if possible.

Microwave lost all power when I pressed start


Plug a lamp into the circuit where the Microwave is plugged in. If the lamp comes on then you know there is power supplied to the microwave and the problem is one of an internal nature. If your light does not come on then your breaker at the main power panel could have tripped. On each breaker is a number which is its rating in amps. Your Microwave may require a 20 amp circuit.

GE Spacesaver microwave trips the circuit breaker


Since power = voltage X current, 1.58kW / 120VAC = 13.166A

So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.

Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.

Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.

A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.

If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.

If it passes this test, the problem is likely in the microwave.

We're happy to help and we appreciate your thoughtful rating of our answer.
