Articpro ac unit trips as soon as it is plugged in

If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

Check to make sure that in the process of moving a "hot" wire under the refrigerator did not come loose and now is contacting a metal part of unit.

U have a classic short circuit which accounts for the breaker popping immediately. It is not a short in the compressor because that would have popped the self resetting clixon and not the house breaker.

With the unit unplugged remove the machine compartment and visually inspect for and burnt marks or frayed wiring. if non is seen, remove the wiring connectors from one component at a time and re test by plugging the unit back in. This will help you isolate the issue hopefully.
The machine compartment is on the back and the power cord is attached behind it. It is usually connected with 1/4" screws so a socket or nut driver will help you gain access.

Hello jerrydj1021 - Often when the breaker trips, it is a mainly because there is too much current running on one circuit. Is the unit plug into a GFI outlet? It is not recommended to use GFI outlets or too many appliances plugged into that one circuit. Try plugging the unit into another direct outlet and see if the breaker trips again. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if the unit's status has changed successfully. Thank you.

First check the outlet the unit is plugged into. It may be dead, due to a circuit breaker being tripped. Also, the interior of the outlet may be damaged or has a loose wire.

If a circuit breaker was tripped, unplug the unit before resetting the circuit breaker. Then plug the unit back in and turn it ON. If the breaker trips again, there may be a short in the AC wiring or there is another electric appliance on that same circuit, that may be causing an overload, when the AC unit is ON.

Hope this helps you to start troubleshooting the problem. Thanks for choosing FixYa.

Hi,
There is nothing you can do to fix it... the compressor is trying to start and cannot so it trips the plug. The plug trips to protect the house circuit from being overloaded and causing a fire.
Getting the compressor replaced is cost prohibitive, it is cheaper to buy a new unit.

Jacob, it would seem from what you have described, the AC unit has an electrical fault in it somewhere. Or the receptacle may have a wiring short, loose wire, etc. If you can, try plugging the unit into another receptacle, that's on a different circuit than the one you're now using. That way, if it trips again, it's in the AC unit, not the receptacle. In which case, you can either get a continuity tester or multimeter and check all the circuits in the AC unit to find the problem. Then locate the part(s) you need and repair it yourself. Or you can arrange to have it repaired. It may be something simple like a loose connection or it could be more serious. Weigh the cost of repairing it against purchasing a new one. Then make your decision from that.

Hope this helped you troubleshoot and solve the problem.

For it to continually trip, there is some sort of short either in the AC Unit or the outlet it's plugged into is damaged or faulty. If you can, plug the unit into another outlet, on a different circuit. If it continually trips again, the fault is in the AC unit. In which case, contact Delonghi Technical Service. 800-322-3848.

Hope this helps you troubleshoot and solve the problem.

This is only a 5,200 BTU unit - for single room use.

If you're sure the voltage ok, it sounds like the unit is new and should be under warranty.

You are trying to draw too much power from the dedicated electrical line, or you may have an outlet that is needing replaced. Try to use another plug, in another room to test
