I have had it for years. This Summer it was working fine, Then one day I went to the sun room where it was located and the room was steaming. The unit was blowing hot hot air. I can turn it off or unplug it and it will cool again for a while. Interesting is that when I have it turned off but plugging in I van still heaR COMPRESSOR NOISES.
CLEAN YOUR COILS AND CLEAN THE FILTER. THE DUST, DIRT, DEBRIS IN THE COILS ARE PREVENTING PROPER AIR FLOW, CAUSING THE COILS TO FREEZE UP, PRODUCING WARM OR HOT AIR. WHEN YOU TURN IT OFF, THE ICE OVER THE COILS DEFROST UNTIL YOU TURN IT ON AGAIN.
To clean the coils:
1. Remove the front cover of the PTAC Unit.
2. Unplug the PTAC unit.
3. In a spray bottle, add 4 bags of UNSWEETENED Lemon-flavored KOOL-AID, and fill with water. Shake well to mix.
4. Spray the coils with the entire solution and allow to sit for at least 30 minutes to allow the CITRIC ACID in the KOOL-AID to clean those coils.
5. While waiting for the coils to clean, take the filters and THOROUGHLY clean them. Bump them and shake them to remove any unwanted water.
6. Fill the same spray bottle with clear water.
7. Plug your PTAC unit into the receptacle; and turn your system to the COOLING mode, HI Speed.
8. While the system is running, spray the coils with clear water to thoroughly rinse the coils.
9. Replace the front cover to the PTAC Unit.
9. Replace the filters.
10. Enjoy the comfort of your PTAC A/C Unit.
Cooling gas is missing. Call some AC service in near to fill it, ask more of them for price. Do not switch it on until you solve this to prevent higher damage.
SOURCE: dehumidify mode also cools
Some units do cool/dehumidify only im afraid why cant you let the unit dump its hot air into the room then it wont heat or cool the room?

Heat pumps have saftey circuits that prevent liquid flooding of the compressor. Inadequate airflow across the evaporator in cooling can trip this circuit. Have your package unit serviced with particular attention to cleaning the evaporator coil and be sure your filters are clean and changed frequently in the summer months. Hope this helps GL!
SOURCE: Will not cool properly.
You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze

I just posted this on another one, but try unplugging it and pushing the reset buttons on the side of the plug. It worked to fix mine so far...
