How long does it run, is it consistant? Some units are equipped with economizer software built into the controller/thermostat intended to capture the refrigeration effect as the internal pressures equalize. If equipped it works like this, thermostat shuts down the compressor a couple degrees above the set-point, the fan continues to run taking advantage of the continuing refrigeration provided after the compressor shuts down there is still pressure pent up the Freon continues to pass through the metering device to the low pressure of the cooling coil and continues to cool as the pressure bleeds down. If your machine does not have this feature you have a bad controller, call a tech.

e5 is comp overload code . if you have infared remote for indoor units point at anyone while pushing all 3 buttons at the same time- 'mode' 'temp up' temp down' this will bring up OO where temp set point is normally displayed. scroll up or down with temp up or down buttons (1st digit only) untill you here the beeping sound change tone, this is the 1st part of the fault code. press mode once to change to 2nd digit, scroll again with up and down listening for change of beep- 2nd part of code ie "E5". press mode again will bring up afunny looking T-test mode. press mode again to exit. THATS VERY ACCURATE SOLUTION.SAVE IT FOR FUTURE.WISH U SUCCESS .REPLY FOR FURTHER ASSISTANCE IF REQUIRED.BYE

simply "adding a can"is a good way to end up with non-functional A/C. the typical system has high/low pressure switches that enable/disable the system. you need to be at the correct volume of refrigerant as specified on the sticker under the hood. i recommend using the proper equipment, evacuating, pulling a vacuum, and then refilling the system with the appropriate amount.
