Power recommendation.
Check if the unit have an adequate power supply, the two scenarios below are the most common.
Unit requires a 208/230 volt.
The outlet must be rated to provide the proper power level to the unit. If you only changed the outlet to match the power cord plug, but did not have the outlet rewired, then the unit will not be receiving the correct power.
Unit uses a 115 volt.
The outlet has the correct voltage, but the breaker is tripping and causing the loss of power. We can to perform a simple test to see if other devices are powered on the same circuit as your air conditioner.
NOTE: Check the specifications for your model to determine the power requirements. Your model's power specification is described in the owner's manual. Visit our Manuals and Documents page to download your copy.

Install unit on dedicated circuit.
AC units are built to operate on a dedicated circuit. Test the unit with other appliances in the room to know if its running on a dedicated circuit.
-
Turn off all other electrical devices in the room besides the air conditioner.
-
If the unit runs fine with other devices turned off, then likely the unit is not on a dedicated circuit breaker.
-
If the unit is NOT on a dedicated circuit breaker, the unit may power on but not run.
The reason for this is the unit does not require as much power to display the settings, or even run the fan, as it does to turn on and run the compressor. The A/C must be on a dedicated circuit breaker and not share with other outlets.
