Make sure that you are plugged into a 20 amp circuit minimum, if possible use a 30 amp circuit. Next, are you using the cord that is attached to the unit and only that cord? Do not use a regular extension cord unless that cord is rated at at least 20 to 30 amps. The ac unit will draw alot of power at the initial startup in order to start the compressor and using an extension cord is not recommended. If you are doing these things correctly, cord from the unit and the proper rated circuit, the problem may lie in the ac unit itself. There is a capacitor that needs to be checked to be sure that it is functioning properly, cost is around $30. The next thing to have checked is the compressor itself. Good luck.
