9000 Koolfront portable unit cools after being off but within a minute or to compressor cuts off. After removing exhaust cover fan running very slow. What is controlling the exhaust fan speed.
I JUST BOUGHT A 9000BTU PROTABLE AC MY QUESTION IS IF I REDUCE THE EXAUSTE FROM THE ORIGINAL 3" TO 2" WILL IT BECOME A PROBLEM WITH THE AC OR MALFUNCTION
Sounds like the compressor is turning off cause of high pressure. check the coil that the exhaust hose connects to, if dirty clean it. if the fan is not blowing enough air threw the coil the unit will build up high side pressure and cut out, but will turn back on when pressure drops. if that dont help, maybe the fan motor is bad or needs taken apart and oiled.

run capacitor or motor going bad
There is a run capacitor in line with the fan. This is probably faulty.
