Ac is still cold. Set thermostat lower, but still restarts too frequently.
Changing the setting won't affect the way the unit works, only how long it runs for. Rapid switching off and on will kill your compressor in time - check the refrigerant level. Usually short cycling on lp switch.

I CHECKED FOR ONE THEY WANTED 75 FROM MITSUBISHI TO REPLACE BUT I GOT UNIVERSAL REMOTE ON EBAY FOR 12 DOLLARS IT WORKS GREAT!
SOURCE: pressure in both lines fluctuate from 140psi to below 30psi
The foreign made market is different than the USA.
First if the unit doesn't get a change or input from a manual command (on the remote on mine) it will shut off because it assumes there is no one there.
2nd if it is in the timer mode it may be different in orientation than what you are used to looking at.
TO make sure these are not your problem review the instructions.
If this is R22 or R410A there is not a pressure switch that will cut it "OFF" at 140#. And if your fluctuating tween 30 and 140 It is almost sure its low on charge especially if its new. Now I assume you mean 140 on the high side, right?
