1- check the fuse must support the current of the unit not less than (rla of the unit)
2- check freon pressure may below or toohigh causes compressor winding over heating
3- check fan motor winding

Desert master carrier ac compressor is leaking and due to leakage it is taking too much ampere due to it trips the breaker. what i have to do change only the compressor or the whole unit?


If only the compressor is faulty then you can repair it by just changing the compressor. This is a specialist job that requires specialist equipment and you wont be able to do it yourself unless you have this equipment. I suggest you contact a refrigeration repair service and get them to check it out.

I recently bought a used RV Carrier AC unit for my older camper. After installing the ac will work for about ten minutes before the breaker trips. If I reset the breaker the problem will repeat itself. ...


It sounds like the compressor is opening a thermal overload which is shutting the unit off. When the compressor cools down the switch resets and the process repeats itself. In the end it sounds like the system has a leak and is therefore low on Freon. This will cause the compressor to overheat and open the thermal overload. The freon cools the compressor windings and if it is low they will not be cooled sufficiently and hence the opening of the overload, which is a bi-metal sensitive to heat/cold.

Is an ac compressor supposed to constantly run on a 95 nissan 200sx


If an AC compressor runs continually then the vehicle's system thinks the AC is on MAX which should only be used in desert conditions. The compressor should cycle on an off when it is on normal AC.

Samsung Ac compressor stops after 20 minutes and fan keep running. Again after 10-15 minutes if ac is restarted the cooling happens for 20 minutes and compressor stops.


eventually,cycling process is doing done if the thermostat sense the configure temperayure set up it will trigger to stop your compressor motor as well as the blower fan,blower fan independenly to you compressor.if your thingking that your compressor is tripping off,check your operating current on one line using clamp ammeter and compare to the rated current that tag on
motor compressor body,if the current flow is higher than the rated current specified on compressor motor,well problem occured it will trip your compressor,because overload protector is becoming your thermostat.but if you got same current result it was cycling process.If tripping off maybe air is present in your system call qualified ac tech, to purge out air in system.

2 problems.. AC Comp cuts out. And Fan will not stop.


Unit#2 -Sounds like the contacts on the master switch are welded closed or the switch is broken, Replacing the switch should fix this unit.
#1 is a little more difficult to diagnose. The compressor is being taken off line by a circuit that protects the compressor from damage either; 1- liquid refrigerant getting back to the compressor which can be caused by something as simple as a clogged return air filter or evaporator coil on a heat pump or 2- overload situation caused by a bad condenser motor or a clogged condenser coil. The first thing you need to do is clean both coils and replace the filter,. Then check to be sure your getting good airflow across both coils. I think it's most likely an airflow issue I hope this resolves the problem GL!
