Taking high ampere and tripping

can not find much here but it seems like the air filter is pluged

there should be some loose connection or short circut, that is the only thing that can cause it.

( 1) You have a problem with a motor faulty.or main motor faulty or transformer.

2) The test that you did is good.

3) That means that motor is possible in short circuit.
4) Since the breaker is triiped that means the motor is consuming more ampere that normal, that indicate some possibles troubles inside the motor: a) Winding Short+ ground(carcase). You mus repair the motor or buy a new one.
5) One more thing you must to test the Main Motor controller board, that controll the Main Motor, possible Faulty.

Attached the block diagram for better ilustration that I did and you can use for better understanding.

Hello, the answer is no. This inverter will work with a pump that below or about 400 watts power for operation. I notice it says that the inverter 400w/800w. The 800 watts is the surge required to get an electric motor to run. On a single phase motor (120 AC) and it take 4 amperes to operator this motor. But to start the it will 12 amperes to start it. This is one reason why on a lot of electrical motors there will be a big tube or can, this is the starting capacitor, it stores energy in form of current (amperes) to drop across the windings of the motor when it starts. If some electric motors didn't have this capacitor. The most likely scenario would be tripping a breaker because it drawing to much current.


Now, for you problem. Example of Power and the unit of the formula is V (volt), R (resistance) I (current) P (power) Ohm's states that :




Now Power would be stated: P = V times(x) I. Therefore in your case, if the pump at normal operation is drawing 4 amps of current for operation pumping water. The power factor would be 120 V AC (house voltage) times (X) I (current) which 4 amps. So here is what you have: P = 120 X 4 equal= 480 watts.

Therefore, your inverter will not work because it operating at 80 watts more than the power inverter can deliver which is 400 Watts.



If you need to purchase a new power inverter, remember always take into account the Amperes required for operation. Just by the simple Ohm's Formula. Best of Luck. GB....stewbison

Hello,needs freon recharge.

Maybe your are in low voltage thats why amphere is high.

dear sir,
this types of problem occurred due to reason given below:-
1) if your motor belt too jammed. motor need more power to rotate it.
2) motor internal coil insulation problem.
3) semi short circuit in the internal control circuit.
how to check :-
at first look the label on motor try to find out the motor Ampere then measure with a ammeter if it drawing current is high from label mentioned ampere
then motor is faulty.
for check the circuit if u don't have any previous idea plz contact with qualified technical person.
hope that u get the answer.
thanks

take the units total wattage and devide by the input voltage i.e. 3000watts/120 volts=25 amperes

hi! there;
there are several causes we can consider in tripping of unit on auxillary sensor.the sensor device was designed to cut off source at specific limit of time or load.the over load sensor device was equipted to the main source specially on cmpressor of chiller to protect of burning the motor.
common causes of tripping off unit
1.high current on supply source.you can check this on one common line of compressor.using clamp ammeter.what ever reading you got when unit is running,compare this on rated current on manuals if high ampere was registered.ther is an overload supply the over load sensor will activate and cut off your unit.
a. source of overload is due to obstruction on refrigeration system,filter dryer are clogged,excessi9ve oil on high side.
b. themostat not cycles on,due to poor condensing fan, dirty condenser fin tube,or condeser insufficient cooling effect.
c. bearing,lubrication are not maintained usually on compressor on open type unit,

2. electrical wire and electronic control board short circuited.
a.sometime relay malfunction on cantactor w/c the supply souce intermittent either on one line supplying compressor,the compressor will suffer,it will just hum and trip off,

b.busted capacitor will trip off your unit,due to in the absence of starting motor.
this are common ways unit trip off, so regards and have a nice day,and one thing more don't forget to rate me, thank's

hi! that symptom correspond hizzing sound on evaporator.factors are to be check before you can diagnose insusfficent cooling effect check your actual opearating current using clamp ammeter,set to amperes rating,clamp to one line source take thereading,compare reading on the tag locate at the backside of freezer there is rated ampers indicated.if you got low amper rating your system is under charge,thats the time you recharge your system by qualified ref/ac technician.but if you got high amper rating your filter need to replace as well as your refrigerant.check also the high side pressure by service pressure gauge manifold or the compressor discharge pressure if can compress to 300 to 500 psig.if not your compressor has loose compression.compressor is worn out.
