Thank you for posting your question here on Fixya.com.

It could be the pump is bound up but it is more likely the motor is failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.

Can the motor control board cause the house circuit breaker to trip?


It's unlikely. An internal fuse would blow first, I'm assuming. If you've diagnosed this far you sound capable of continuing. Electricity is dangerous!!! I would remove all things from the board, 1 by 1 plug each component into board until the breaker trips. That should pinpoint what is tripping breaker. I would assume a motor.

Breaker trips on startup


If your circuit breaker is tripping when you turn the pump on it is caused by a bad motor. The motor probably has a short in it causing the breaker to trip,
Replace your pump and that should solve your problem with the breaker.
There is an outside chance you may have a bad circuit breaker too.

I have a Polaris PB4-60 booster pump, less than 3yrs old. I turned the pump and left. When I got back 1hr later, the pump was not running. Breakers had been tripped. Each time we reset the breakers and...


If the device that tripped is a ground fault circuit interupter (GFCI) breaker or receptacle then it is likely caused by 5mA or more of leakage current to ground within the motor. If what tripped is a circuit breaker then there are likely shorted turns within the motor. Usually either of this issues requires a new motor.

If you are not wanting to turn wrenches yourselfthen my best suggestion is to bring it to Leslies Pool Supplies and they oftencan put it right for the price of the parts while you watch (they might not have some parts in stock).

I hope this helps.

Breaker trips on unit. Fuse in house is ok. As soon as AC unit turns on it trips the breaker outside next to unit.


you have a 'direct short' - most likely the compressor or fan motor.
you could isolate it to one or the other by (be sure all power is off) disconnecting one of them and turning the unit back on.
For example if the fan motor is shorted and you disconnect it - the breaker will hold and not trip and the compressor will come on - which will tell you that you need to replace the fan motor.
If you do this and it still trips the breaker then reconnect the fan motor and disconnect the compressor and try that.
If the breaker holds and the fan motor runs then you know the compressor is shorted.
Note: the fan motor can be replaced with not a lot of trouble depending on how mechanically inclined you are - but the compressor will take a qualified serviceperson.

Kenmore central air conditioning unit tripping breaker each time we turn it on.


The breaker tripping when you turn the unit on indicates a 'direct short' and 99 out of a 100 times the short will be either the outside fan motor or the compressor itself. Either way - you will need a qualified serviceperson to diagnose this problem correctly and make the needed repairs.
Best solution is to call AC person.
However, here's a good way you can get it down to either the fan motor or the compressor.
(1) With all power OFF - disconnect the wires to the fan motor
(2) turn on AC unit (a) if breaker trips it means the compressor is probably the shorted component. (b) if breaker DOES NOT trip and the compressor runs - it means the fan motor is shorted.
(3) If breaker tripped with the fan motor disconnected meaning the compressor is probably shorted you can then (with ALL POWER OFF) 'disconnect the wires going to the compressor' and re-connect the fan motor wires. Turn on power - and if fan motor runs (with compressor wires off) you know it's the compressor that is shorted.
After all this you will now know which of the two (compressor or fan motor) is shorted.
If it's the fan motor you can with 'limited mechanical experience' change the motor yourself, but if it's the compressor you will need to call a serviceperson because of the expertise needed to replace the compressor.

Sounds like you may have overheated the motor. I'm surprised the overload on the motor didn't trip first. With this overheating, the windings in the motor have basically shorted out to ground. This is why your breaker is tripping. Rewinding the motor is no longer the option these days. You can try going online to www.searspartsdirect.com

try running up this motor when its not installed on the compressor,, if it still blows the trips the motor is faulty,, if it runs ok, but hums when reconted to the compressor the compressor if far to tight for the motor to turn the compressor,,,you can not reset the points in a breaker trip they trip at a set curent if the motor is pulling more amps than the trip is set for it will trip the trip to turn off the curent, the motor will pull far more amps than it should if its over loaded thats why its humming its trying to spin up it but cant so it just keeps pulling more and more amps till the trip cuts out

Washer starts to spin up then trips breaker


Good day,
Not the transmission. The motor could be stalled by a defective transmission, but the motor would trip off on it's own internal long before the home breaker.
Sounds like a short in the motor itself. But ......
There is Murphy's law.
Your home breaker might have become so weak, it IS the problem.
You really need an amp probe to check the washers draw, at the circuit breaker panel.

If you cannot do that and are comfortable dealing with electrical, you can swap equal value breakers, to be sure.

Intermatic t10004 control panel trips the circuit breaker


That circuit breaker is letting you know that you've got a problem in the electrical wiring.... What's next is to turn the power off to BOTH legs of the breaker.
Begin by physically inspecting all the connections in the timer box, and at the breaker and all the way to the pump motor. Make sure all connections are dry, and there's no water in any of the conduits...this will cause a short circuit and trip the breaker. If there's any bare power leg wires touching a grounding point , this can cause the breaker to trip. Lastly check the motor on the pump; on the motor end, there should be a cap you can remove and use a crescent wrench to make sure the motor shaft is moving freely. It could be jammed with debris....this happens around my pool often because I'm surrounded by trees with needles. If the motor cannot turn freely, this will cause the breaker to blow... I'm pretty sure that your timer isn't the issue... Please let me know what you find out.
