Why would the compressor on a shinco ap1400 portable ac come on but no cold air be blowing out?

If the compressor on a Shinco AP1400 portable AC is running but no cold air is blowing out, it could be due to several issues. One possible reason is low refrigerant levels, which can inhibit the cooling process. Another possibility is a clogged air filter or condenser coil, preventing proper airflow and cooling. Additionally, a malfunctioning compressor or a faulty thermostat could also cause this problem.
