If the fan and compressor are shutting off. its possible its cycling on a low pressure switch. probably low on freon.

or you have a low ambient kit to keep pressures up during low outdoor temps while ac is running just the fan will shut off, however thats not a typical thing to have a residential system

I have a split air conditioner my out fan keeps


It depends on the effiency of the unit. The fan could be cycling because the condensor coil is not hot enough. When it get hot enough the fan will turn on. If not you have a bad fan motor

Split unit, I get heat but no cold


I have run into this with the LG brand systems. try shutting power off to the outdoor unit to reset all units. If problem persists, it could have to do with a charge level of refrigerant (freon) or possibly a failed control board.

Carrier split 42G250HF-1(indoor unit


I'm not sure exactly what unit you have and what controls you have installed on the unit. But....there usually is a flash code schematic on the unit. Usually on the inside of the blower compartment cover. This should tell you what is wrong with the unit. It could have a low voltage short somewhere and is loosing the call for cool. So the answer can be a possible yes to your question but without knowing the flash code, it's hard to tell from my point of view. You might end up calling a service professional out to check it.

Airconditioner LG LSk181-N2 shutting off


Sounds like your aircon is stuck on heating mode. Or. The outdoor fan speed is affected by ambient temperature, or low refrigerant. In heating mode the indoor fan will come on for a while to sense temperature and will then wait for the outdoor unit to pump up pressure and build up heat.

Evaporator unit turns on for about 15 seconds then turns off


Out of range thermistor can cause the tripping of indoor or outdoor unit. Try to check the resistance of your thermistor it should be 8 to 10 kilo ohms at 25 deg. c temp.
