May be low on refrigerant, May want to pull out the unit from the window and see if you see any oil spots anywhere, inside where the coils are at or around the compressor area where copper is located.
If so you will need to call a local Ac company to repair the unit.

GE Zoneline HP PTAC A3B688DAALW1 WIRING DIAGRAM? Found a 6" L white wire with 1/4"F stake-ons loose from center terminal of Compressor capacitor 20/5uf going into the back wiring compartment. Not sure where it came loose from. There is a black multi stake-on terminal block up inside behind the capacitors. Attached it there to a unused spade but now fan does not run the indoor fan when in heat mode (compressor or elect. heat). Before the fan and electric heat worked but compressor just buzzed trying to start every 45-60 seconds. Elect heat had worked OK if turned all the way warmer past compressor mode.
