Refrigerant is the lifeblood of the cooling process, and a leak is a common reason for failure. A capacitor or contactor failure might allow the fan to operate while starving the compressor of the necessary power to function.
Outdoor AC Unit Not Cooling: Common Causes and Solutions
Initial Checks and User Errors Before diving into technical diagnostics, it is crucial to rule out the simplest explanations. Additionally, verify that the fan setting is not stuck on "On," which circulates room air without engaging the cooling cycle, or that it is not set so high that it blows out warm air faster than the system can cool it.
A failing compressor may struggle to circulate the refrigerant, causing the system to run constantly without achieving the desired temperature. Evaluating Electrical and Control Systems Electrical issues can also manifest as a running unit that does not cool.

Often, the issue lies not with the machine but with the settings or expectations. A frequently overlooked culprit is the thermostat; ensure it is set to "Cool" mode and the setpoint is lower than the current room temperature.
