My split air conditioner compressor fail is it due shot pipe length total pipe length less then 1.5 mt.unit is 1.5 Tr and room size is 160 sq ft.using steblizer.
Re: My split air conditioner compressor fail is it due...
A/C compressors fail because the system is overcharged, not enough charge in the system. Compressor can also fail if it's started before it has a chance to cool down first.

Check for communication from indoor to out door.Check power in out door unit. If not, check the following. Keep cool mode and temp setting minimum 3 degree less than room temp. Check indoor unit return air sensor. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace air sensor
Check Indoor Pipe Sensor Disconnect from PCB and measure resistance. Pipe sensor = 5kOhm at 25C. If not replace pipe sensor. Thanks and hope helpful?
There's a thumb rule in A/C air distribution. At 1 TR load, the air supply is about 400 CFM and the ideal diffuser size is 16" x 16" with an effective flow area of about 70%. Branch duct size for this outlet should be around 12" x 12".
The length of line set can dramatically effect the efficiency and operation of the air conditioner. There is a science behind the design and application of the different sizes. Refrigerant carries oil in it as well as the refrigerant itself. The length can change the amount of oil that is supplied to the compressor. The length of pipe can change the indoor coil's ability to flash to vapor gases.
The instructions that came with your unit should be able to simplify this for you. There will be minimum and Maximum lengths and possibly even some graphs and tables to study.
