My dryer is an lg tromm dle7177rm. it is 220v. it has ran fine for 3 years but now trips the breaker within 5 min.

If your breakers are old. I'll start by replacing the breaker to the dryer at the box. It is a common failure. Breakers wear out to. Check the power cord for any burnt markings and look at the outlet as well for burnt or discolor contacts. This will overheat as well causing the breaker to exceed the limit and trip it.

Circuit Breaker Keeps Tripping

Your circuit breaker keeps tripping and you are wondering why it would do that. There actually can be many things that can cause a circuit breaker to trip, or shut off. I will give you some reasons why circuit breakers trip and also some circuit breaker troubleshooting tips.

The first thing to remember about a circuit breaker is that they are first and foremost a safety device. The protection provided by the circuit breaker is also two fold. The circuit breaker will protect against overcurrent, or in other words, it will keep you from melting down the wires by placing too high of a load on any circuit. This would cause the wires to overheat and start a fire.

The other way a circuit breaker protects you is that the circuit breaker senses very quickly if there is current flowing to the ground with out it going through a load. This means that there is a shock hazard or a fire hazard. The circuit breaker will interrupt the current and shut off to prevent damage from happening.

If your circuit breaker is tripping off then you need to find out why this is happening. By eliminating the load on the circuit you can start to narrow down the possibilities. If there are a number of things plugged into the circuit then unplug something till it will stay on.If you can get the load low enough so that the circuit breaker stays on then you are okay and just need to spread the load out over a couple of circuits to prevent the overloading.

If you cannot stop the circuit breaker from tripping, unplug loads until you narrow the problem down to one thing. Once you narrow it down to one thing that is tripping the circuit breaker then you can find out why the load is tripping the circuit breaker.

Now if the load that is still plugged in is an appliance like a washing machine, then you need to find out if the cause of the tripping is the motor or if it is something like a wire that is rubbed through and is shorting out. If it is the motor the circuit breaker will often trip right when the motor goes to start up.

If the circuit breaker trips immediately when power is applied then you probably have a bad wire or connection. Poor connections are common in appliances such as an oven or a dryer where high amounts of current can be pulled at one time and the heat will make the connection get hot and eventually fail.

There are so many different possibilities for circuit breakers tripping that it is impossible to cover them all. There is one tool that will make the detective work of finding a short or problem much easier.This tool is called an "OHM" meter. One of these can be purchased at most any hardware or electrical store. Many big box stores and even a Wal-Mart also have them. There are many very inexpensive models available.

By using an OHM meter you can check the resistance of a circuit. The idea is that if a circuit has NO resistance to ground then it is bad and the electric can flow to the ground unhindered. This is a dangerous situation and must be corrected. In motors the flow of current between phases with no resistance, is also a reason why a circuit breaker will trip.

Above all remember that you need to verify and make sure that all electric is shut off to any piece of equipment that you are working on. Isolating and finding electrical problems can be very time consuming and frustrating. It will take time and patience to methodically eliminate the possible causes of a circuit breaker that keeps on tripping or a circuit breaker that will not reset. Through careful checking you can one by one eliminate the possibilities and find the cause of your circuit breaker not staying on.

Probable causes, by most common to least common are:
1) Heating element ( a coil of special wire inside a heating box) has broken, needs replacement.
2) One of the overheat sensors has "tripped" and needs replacement. ( There are from 2 to 6. )
3) A wire has burned in two, needs repaired ( usually near the heating element).
4) A wire has burned or broken where the cord attaches to the back of the machine. Needs repair.
5) A circuit breaker has tripped in your fuse box, wherever that is. (In your hall, garage, basement, or wherever) Needs reset.
Be blessed.

Amana electric dryer LE8317W2 tripped circuit breaker. Orange wire fried at end by heat element and was off terminal end. Also the purple wire was fried at thermostat end. I cleaned up connections and...

These units are totally repairable and will run for ever. Need to assume that other damage has occurred as a result of the failed shorted terminal connections.

Possible that the circuit breaker is defective caused by the dryer failure.

Assume that one of the components has shorted to the grounded frame of the dryer.

The 11 ohms of the heater is about right.

Confirm that heater element is not shorted to the dryer frame (heater housing)! This condition would have caused the initial wire terminals to fail and now trip the circuit breaker!

Use an ohm meter and check resistance between hot leads on back of dryer. Check resistance between each hot and neutral.

There is a switch located on the motor that connects power to the heater. When the motor is running the centrifugal switch closes. This saftey circuit confirms that the blower is running before heat is turned on. Check that the switch is not damaged from prior terminal short circuit failure, Repair kit is p/n WPL-501218

Timer is the next check. Same thing confirm that no damage to the switch circuits has occured. Last check thermal fuses and thermostars for short to netural.

Hope this helps?

Disposal was jammed. I unjammed it and it worked fine for just a few times. The blades now turn freely, but now it trips the circuit breaker the instance I turn it on.

Sounds like the motor windings are toast. The breaker is supposed to trip before the motor overheats too much, but this is an approximate thing in practice. The varnish insulation on the windings gets soft when it overheats, and if it happens repeatedly (by resetting the breaker multiple times in a short time period) the insulation eventually breaks down and the coil shorts out between windings. This makes a coil that is supposed to be, say 100 turns, act like it has say 5 turns, which makes the overall resistance of that coil a whole lot less than it's supposed to be, which increases the current level it takes to maintain the voltage potential (120V) across that coil. The high current load trips the breaker. Sorry for the long explanation. I got a little carried away. Time for a new disposal Good luck, Al K

My dishwasher smells of burning and it tripped the electric

There are couple of things it could be...the most likely is that the motor has gone bad...they will smoke first and then trip the breaker...if you get under the dishwasher you will be able to follow your nose right to the motor is that is the problem...
The other possibility would be that the heating element went bad and melted something before it shorted and tripped the breaker...that to your should be able to see rather easily in the bottom of your dishwasher...
At either rate you should be able to smell the problem or see the burn marks...

Smoking from the outside

Hi, it could be several things that good do something like this. This is a window unit so the blower/condenser fan motor is a dual shaft motor, one shaft blows air across the indoor coil for cooling, while the other shaft of the motor keeps the condenser coil on the outside as cool as it can and to keep the freon head pressure down. If this motor and all just shut down on you and shut the whole system down with smoke, it sounds as though this combination motor as died on you and burned out the motor windings which will cause electrical smoke. It may have tripped the breaker in the process. I would turn the unit to off and go check your breaker. If it is tripped, turn it off hard and back to on hard to reset it. Go back to the unit and while watching it, turn it on cool high and see if the unit trips out and stops again. If it does, more then likely, you have lost this motor. On a compressor burnout its not very often you will see smoke coming from one unless the terminals blow completely out. I have only seen this happen 2 times in 33 years of a/c repairs. Anyway, to gain excess to this motor and compressor the unit is made inside of the case. It is made to slide the whole inner workings from the inside, (most are anyway) for the tech or owner to work on them. Like a sleeve in a case that slides out into the room. You can also if you have a long screw driver or metal object that is slender and long enough with the unit unplugged, try turning the blade or wheel which ever it has to see if the shaft spins freely. If it does not spin or is very hard to spin, you will know the bearings were going out and this is what caused the motor to overheat and burn out. Try and do these checks for me if you are able, and keep me posted on the out come. If the motor seems to be fine after you reset breaker if it was tripped, we can go into it deeper. Try and keep me posted and I will get back to you as soon as I can.

How to manually reset an AO Smith 2 hp motor?

If you did not press a reset ( and even if you did) the motor is damaged and that is causing the circuit breaker to trip. You need to have the motor inspected to see if the damage is repairable or if you need a new motor. A local electric motor repair shop should be able to take care of that for you. The thermal overload has reset itself if after cooling down the motor is trying to start but trips the breaker.

To be certain it is the motor, disconnect the line leads and be sure they are insulated from ground and one another. Turn the breaker back on. It should stay closed which confirms it is the motor tripping it when connected.

If for some reason the breaker still trips, there is a problem with the electrical circuit feeding the pump.
