Change the sensor assembly and all will be fine, about $30 from Appliance Factory Parts on line store, about an hour to do, all that is needed is Phillips screw driver to take unit apart.

The model number would be on the right hand side of the outdoor unit and same on the indoor unit if it is a midwall split. If it is a flat cassette cieling type you may need to open the grill, which is simply two little levers either side of the grill, and the grill will swing open. Without the model number it is difficult to give accurate info. However, I can offer the following. One, check the condensate drain. You can just blow into the drain pipe from the outside and this sometimes clears clogged mud in the drainpan. Or two, error reading can also come from phase failure (in the case of a three phase unit) or power related problem. This can be solved by switching off the mains and then switching on again to reset. If you have a phase failure you would need an electrician to confirm that the power supply is good. Unless you have a volt meter.

Well it needs to be fix by a professional, so if you or someone you know are good at tinkering go for it. It as a sensor problem at the evaporator.
