Unplug the unit and remove the case cover. Look for a blown fuse. If ok, check that the door interlock switch(es) are clicking when the door is latched. Any 'micro-switch' that doesn't click is likely faulty and needs to be replaced. If you find a blown fuse, the magnetron circuit has two components that commonly cause the blown fuse. The first is the high-voltage diode in the power supply could be shorted, the second is a shorted 'stirrer' (a fan-like device located under the metal wave-guide where the energy comes into the cooking cavity) plastic bearing that has arced over inside it and that shorts out the microwave energy which blows the fuse. Replace the stirrer as a unit.

Sounds like the fuse is blown, you will have take the outer case off to find the fuse and replace it

What size breaker is protecting the circuit? Per the National Electrical Code, a microwave and a washing machine should each have their own dedicated circuit (and own breaker) rated at 20 amps. Also, if the breaker is old and has tripped many times due to continuous overloading, it may be weakened and could be tripping at a lower amperage than what it is rated. I would try the following:

1. If possible, test the microwave on another circuit and see if it trips that breaker. If possible, use a 20 amp circuit for the test.

2. If you're comfortable with working in an electrical panel safely, place a clamp on ammeter on the hot wire of the affected circuit in the panel and see how much current is being drawn when the microwave is on.

3. If you would rather stay out of the panel, get an inline ammeter/watt meter and plug the microwave into this. If the rating of the microwave is less than 15 amps (1800 watts), you may be able to use a device called a kill-a-watt at a local hardware store. This will show how much power is actually being used by a given appliance.

NO internal fuse. It is most likely, the magnetron, and or High power diode. As related In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

SOURCE: Microwave keeps tripping circuit breaker

Chances are you have a shorted "monitor" interlock switch, or its mount is broken.

See this door switch help file.


You can find links to helpful exploded view diagrams and part ordering help here.



To give you more specific help, we would need the brand name and

full model number of your microwave.

When it is running the lights flicker or go dimmer or trips a breaker.


you have too much wattage on the same circuit. microwaves draw 1000-1100 watts typically, something else in on the same circuit drawing another 700+watts and tripping the circuit breaker. lights, refrigerator, stove, fan, hair dryer, etc, etc. if you turn everything else off and you have the same issue, then you may have an electrical issue with your wiring and it could be a potential shorting/fire issue. be cautious, be smart.

Trip Circuit Breaker


The circuit breakers may both be functioning properly. What might be happening is that both circuits have other current drawing appliances on them. The circuit breakers react to the sum of all of the currents drawn by all of the devices on that circuit. So, if you have a 15 amp microwave and an 8 amp refrigerator on the same circuit, you would overload a 20 amp circuit by 3 amps.

Whirlpool GH5184XPS Microwave Oven F7 error, trips circuit breaker


Check the high voltage capacitor, it normally shorts, "discharge with screwdriver" unhook one side and set meter to ohms. Check high voltage diode tied into one side of the capacitor, "unhook from chassis ground" set meter to ohms and check for short, sometimes cracks, "must be replaced" If the diode is open meter does not have enough forward bias to check.

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"

Went to warm up a food item and after 3 seconds the microwave shut off like the circuit breaker tripped. time face went blank, light inside does not light up and stove top lights do not light. circuit...


You have a fuse behind the screen panel. You have screws inside the microwave holding the panel. you have 1-2 at the bottom. You may also have to remove the vent. It has 2-3 screws which will be inside the vent. These can be removed from the front. Once these are removed the panel will pop off and you will see the fuse The fuse can be bought at a radio shack. BE SURE TO UNPLUG THE MICROWAVE! Good Luck

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

Chek the high voltage capacitor and the diode . If one of them are short there is a chance for tripping the breaker

The past Few days the microwave would trip the breaker. today I went to use it and it worked for 30 seconds when I checked what I was heating and turned it bakc on and it would not work


Microwaves that are either built in, a part of the oven, or over the range are on a dedicated circuit by law. This means nothing else could have tripped that breaker but the microwave.
If it has a problem severe enough to trip a 20 amp breaker several times, it is only getting worse each time you reset the breaker and turn it on.
There is a possible chance of fire. I recommend you turn the circuit breaker off and replace the microwave. Is it a plug in, or over the range type?
