If is a newer unit, it may have a type of power supply that uses a diode or diode bridge located pretty close to the input.
I suspect this is shorted.

This is not a job you should undertake since the part may be kind of tough to find if easy to replace.
If you want to keep the unit, look for a repair shop in your area; they might even have the part in stock.

Westpoint dishwasher trips the electricity


is this a new machine that is replacing and old one? because if it is tripping your breakers it means that the machine is asking for more amperage than the breaker is capable to sustain. make sure that you check the amperage rating is on the machine and you will be able to use the appropriate breaker that is needed for it. another thing that could also be happening is, if that cirquit is being shared with something else in your kitchen, these machines are for the most part need to be dedicated cirquits.

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.

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"

Should microwave 1.58 kw be on sperate circuit


The answer is yes. All appliances in your kitchen should have a dedicated breaker.
Microwaves draw a high number of "amps" when starting. Most new microwaves have a 20amp fuse internally, yet the household circuit breaker should be 15 amps.
I'd suggest hiring a licensed electrician to be sure the hookup is to code for your area.

Blowing main breaker


I have a hard time believing that the home's main breaker is tripping instead of the branch circuit breaker that feeds the microwave. I suspect it is really just a difference in terms. You should disconnect it and try using in another outlet - preferably one on a different circuit if possible. If the breaker continues to trip; this appliance should be disconnected and either be discarded, repaired or replaced before using again.

If the microwave works as expected (on a different circuit), it may indicate the original circuit is overloaded. Microwave overs are supposed to be installed on a dedicated circuit. This means only one outlet is on the circuit - no other loads (lights, appliances, etc.) are permitted on this circuit. A microwave typically requires 10 Amps or more when on "high" and will require a significant portion of the power supplied by a 15 or 20 amp circuit breaker. There is little unused to power much of anything else. If other appliances go out when the microwave trips the circuit breaker, you should contact an electrician to have a dedicated outlet installed for the microwave.

I hope this helps!

Powers on will not work


Check the breaker . A microwave oven should have a dedicated circuit plug a lamp in the oven plug in if it comes on you have another problem if it wont come on flip the breaker they can trip just enough that you cant see it is tripped flip it all the way off then flip it back on again see if it works. You might have to do this a few times even if light clock comes on it might be tripped just enough to not let enough power come through use a multi meter if you have one to check the current.

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?

Tripping circuit


Hi lbeaujuin,

You don't say how long this has been going on; I'm going to presume it's a recent development.

Several possible scenarios come to mind. I'd first look around and see if any other appliances have been connected to that circuit. In my area (Minnesota), the electrical code requires that microwaves have their own dedicated circuit and breaker; if this is not the case, you need to see what else is competing with your microwave for that breaker's power supply.

One other possible cheap fix - in case the breaker is defective, try swapping out the breaker in-question for another of the same rating (DO NOT, repeat, DO NOT put in a bigger/higher-rated breaker without having a qualified electrician OK it). If this isn't the problem, it never hurts to have a spare circuit breaker on-hand. Might even be able to switch around with another of the same rating, just understand that you'll lose power to both circuits for the duration of the test.

If it's on it's own dedicated circuit, then it's likely the oven itself with an internal short of some kind. Because I don't know your level of skill in dealing with 110V AC electricity, my recommendation is that you have someone qualified open it up and start checking short-circuits with a multi-meter, observing all safety precautions.

If you've isolated the problem to being the oven, and it's going to cost more to troubleshoot than replace, you might be able to cut a deal by trading-in your old oven against the new one - - if the shop you buy from has quailfied repair people on-staff, they might be able to refurb and re-sell it used.

If I can be of further assistance, or if you have questions about any of my response(s), please let me know before rating me.

If this solves the issue, please rate it accordingly. My goal is to earn a "FixYa" rating from everyone I help.

Thanks for using Fixya.com,

Breaker tripping


Make sure it is plugged into a 20 amp circuit. If it is in a kitchen it should be a 20amp breaker if it trips a 20 amp breaker it needs to be replaced. If it is a new house and you plug it in in the kitchen and it trips a 15 amp breaker then the house does not meet code. ref Article 210.52(B)(1) NEC
