SPLIT AC NOT COOLING AFTER 30 MINUTES

I have NIKAI 1.5 TON AC. It does not run continuesly. For example, if switch it on, it will run for 30-45 minutes and will provide cool air. After that it will not provide "cool air", only fan will run.. When i am checking the "out-door" unit, which is on the roof, it is off. Out door is not running at all.. But, inside my room, its switched on. It will blow dry air now.. Then i m switching it on and off again and again, so that it runs, but with no success. I will switch off it for 30-40 minutes. After 35 minutes, when I am switching it ON, it will provide COOL Air. ........ for 30-45 minutes....... after that, it will not blow cool air again...
Last week, i called on one AC mechanic, he repalaced the "CAPACITOR" inside the outdoor unit. He told me that this is because of capacitor problem.. But nothing has changed since... and mechanic has no answer.. Plz let me know the answer/reason and any suggestion/recommendations.

Sounds like the out door fan is not running and the comp is over heating, rec to start unit and check to see if the fan is running in the first 30-45 min, if not check cap or replace fan motor.

My guess is compressor motor overtemp cutout. So why is the motor overheating? Possibles: Needs bearing oil, bad bearings, compressor too much pressure, overfull with freon, mechanical friction, cooling fan not turning.

Suggest set thermostat to demand less cooling, see if compressor stays on longer.

AC is not cooling


I would say you have a freon leak. May be the outside unit is not running now because the low psi switch has it off because it does not have enought freon.
