Today I had some plumbing that was done at my home and the AC unit had to be disconnected and moved. The plumbing contractor hired an AC contractor to move it. After completion of the plumbing work, the AC unit was installed and the breaker kept tripping. The AC contractor said that the compressor went out. There was no prior problems before this action.
I firmly believe that something was done wrong. Do you any suggestion or comments as to what could have caused this?
O.K. a breaker tripping.....it is hard to say cuz your facts are brief.does the breaker trip immediately when you try to reset the breaker? if so...the contractor's employee probably got the 2 "line" legs going to the same side of he disconnect. OR the high volt wire may have short to ground.if the existing wire is xtreamly old, the sheathing can crack and ground out tripping the breaker, quite possibly water may be in the conduit "finding" a crack and shorting out( the reason i bring this up is because a plumber was there.)
breakers often go bad over time....trip and reset the breaker at your panel. it should feel hard to move.there is a spring in there that has to be tight.if it doesn't make a good snap typr action.replace the breaker.they are cheaper than a new machine and they just go bad over time.
you'll have to get another qualified tech to check it out.i would try isolating the high volt circuit and go from there.
good luck.BEWARE OF THE SALESMAN IN TECH CLOTHING.make sure he is old, has dirty nails /uniform.that is a good indicator of a real tech.he may even be slobby too.

run a fault code check as it appears that the cpu has gone into limp home mode (restricted performance). The cpu runs checks of all sensors and when one gores out of parameters it restricts the engine to protect the unit and accessories.
A 2X protection mode blink pattern can be activated due one of the
following defects.? Loss of REG12V (LVP)*
? Loss of -125V (Single Line)
? Excessive -125V Level (OVP)*
? Loss of Power-ON Signal
? Excessive PFC Voltage (OVP)
? Excessive PFC Temperature (OTP)*Low Voltage Protection (LVP)
*Over Voltage Protection (OVP)
ARE WE LOOKIG AT A CAR OR HOME UNIT HOME UNIT AC COMPASADOR KILL POWER TO AC MOUNTED ON SIDE OF INSIDE UNIT SMALL CAN WITH 4 WIRES TOP OF CAN WILL SHOW SIGHNS OF BOWING OUT,THEY WILL BE # LIKE 5 - 30 MAKE SHURE YOU MATCH # UP WEA RUBBER GLOVES EVEN POWER IS OF THE WILL BE ENOUGH POWER TO GIVE YOU A GREAT JOLT KEEP AN EYE WHAT WIRES GOES WHEAR COMPRESSOR FAN WILL START AGAIN THE UNIT HAS 2 FANS ONE TO KEEP CONDINSOR COOL AND OTHER TO KEEP COMPRESSOR RUNING GOOD LUCK PART $90
Hello, usually if the compressor is shorted to ground it will keep tripping t he breaker. One way you can check yhis is disconnect power to the outdoor unit and use a ohmeter to check each winding of the compressor to ground. You can use the discharge line from the compressor as a ground, you should not read any resistance, if ou do the compressor is shorted to ground and will need to be replaced.
Sounds like an electrical problem.. or the compressor is beginning to fail. Check the wiring connections on top of the compressor for burning etc ... If OK, the compressor may be shorted out.
Make sure the power has been switched OFF before any testing is done.. Usually an LG will show a fault code on the display on the internal unit but a dead short on the comp will happen to fast for this to occur. One way to isolate a compressor fault is to disconnect it.. If the unit runs ( fans etc) with the comp disconnected and does not trip the breaker , then you have narrowed down what the fault is.
Go to the outside unit and see if the compressor is running. It may be hard to hear. If you need to you can disconnect one fan lead so you can hear the compressor. If it isn't running then check the capacitor. If it is running then get the refrigerant charge checked. Also check air filter(s) and make sure the coils are clean.
The fan and the compressor both run off of the same circuit. Have your husband remove the cover on the condenser coils and check for power at the leads that go to the compressor off of the latching relay. If there is power there, then he needs to check the start capacitor or possibly the thermal overload switch (mounted on side of compressor)
You must isolate the problem by disconnecting the thermostat wires that go to the unit. If the compressor does not run when the t-stat wires are disconnected, that shows that the t-stat is malfunctioning, or there is a short in the wiring between the t-stat and the ac unit.
If the unit continues to run after disconnecting the t-stat wires, then you'll have to look in the unit for a stuck relay
It will definitely escape. In fact, allowing that gas into the atmosphere is kind of illegal, as well as really expensive. An HVAC repairer has the equipment to remove the gas while keeping it trapped, do any plumbing needed to move the unit to it's new location, and then recharge the unit with the same freon (though you might need to add some to account for the additional run of pipe). Also, the electrical box will probably need to be moved.
