Had forward CruiseAir replaced a couple of years ago, been working like a champ. All of a sudden it starts just blowing hot air and cycling off - on.

Turns on (Amp Draw 10 Amps), runs 2 minutes blowing hot air then compressor cuts out (but fan still running). After 3 minutes unit completely shuts off. After 3 more minutes unit restarts and cycles again.

Suspect this indicates low freon, am I correct?
