Samsung air conditioners are fitted with a forward system of self-diagnostics, based on the results of which the system in case of a certain malfunction revelation blocks operation of the unit, simultaneously informing the user of the cause of a breakdown. If Samsung air conditioner not working one can remove errors of air conditioners with the help of a corresponding instruction on malfunction decoding. The instruction of the type can be found below.
Air conditioners of the series Samsung AC0…JXADCH belong to the classical models of Samsung air conditioning equipment. They use R-410A refrigerant. This equipment consists of indoor and outdoor units, fuse and control. The air guide duct for this series is not provided by Samsung.

Air conditioners Samsung ACC2400C belong to the cassette-type air conditioners. This is the most successful option for rooms with suspended ceiling and a large area, they can be installed between the suspended ceiling and the usual one. Installation of this type of air conditioners is much easier than ща other split systems. The system of work of this air conditioning includes cooling and filtration of air and its feeding back through the distribution grids.

Air conditioners Samsung APH450PG are floor-mounted air-conditioning units. The refrigerant R-22 is used in the system of these air conditioners. Air conditioners have remote control, timer and air filter. There is a possibility of regulation of the air flow from such air conditioners. They are produced in a classical white color of the body frame.

Air conditioners of the series AVXC1H022 are cassette-type units. Samsung air conditioners of the cassette type are installed in spacious rooms with suspended ceilings. Due to the latest technology, the proportions of Samsung air conditioners are minimal ones. The presence of air conditioning in the room can be found not by the noise of operating equipment, but by the cool air. The air is evenly distributed in four directions.
