if the sensors are okay, it might be the compressor overheating, my portable ac (moretti elite ac) is also behaving the same, especially when i turn the fan to max. the compressor shuts down about 7 mins and turns on again in about 5 mins, now i found out when i turn to medium or low the compressor runs normally. i think when on medium or low setting some of the cool air directs/channels to the compressor thus cooling it more.
have you replaced the ptc overload/relay on the compressor,as this is the actual start and run component that the compressor needs or it wont start or run,remove it by unplugging it off the compressor and a good sign if its bad is it will sound loose like pieces loose inside the ptc unit,you should also replace the run capacitor connected to this component too
G'day .To give you a rough idea. Each one horsepower of motor, will give about 4 cubic feet per minute. Without the make & model of your compressor or motor type & size I can't be more spacific I'm afraid. Kind regards Andrew Porrelli
Please check your compressor pumping. How to check? Keep pressure gauge in discharge pipe and also keep open suction pipe, test run. It builds the pressure up to 300 psi or slightly more than that. If it's less than 275psi, it's defective.
The compressors that come in units change from year to year and model to model. Depending on the age and type of unit, it could be a Copeland, Bristol....just about anything in the 2 ton range.
Best bet would be to look down and on the top or side of the compressor, you should see a series of numbers that have the model and serial numbers. The model would be the compressor you seek and the serial will help to determine the age of the compressor. Also be sure to look for a name brand such as Copeland, Bristol, Tecumseh, etc.etc..
ok..that's good. so the power supply is supplying power to the mother board. just a chance on this one..carefully, after you ground your hands on metal case, remove the memory sticks, and DO NOT touch the gold fingers..re insert them back in the slots, and see if that helps. if not, then it appears the mother board is kaput, and will need replacing.
