Why is my window AC running but not cooling?
The most common cause of window air conditioners not blowing cold air is a lack of adequate air flow. If the air filter is dirty or clogged, there may be little or no air flow over the evaporator coils, which may cause them to become too cold and frost or ice can form on them, restricting the air flow even more.

If the temperature control is running properly, the continuity should turn off.
Can I run my AC compressor without Freon?
With no freon, the compressor clutch will not engage, therefore, the compressor, in your situation, should be just fine once the system is repaired and recharged.
What happens if your AC is low on Freon?
