Defrost cycle may be faulty. They are usually simple timers with contacts that change the reversing valve. check to see if the RV is switching

Freon is low. Sounds counter-intuitive, but the large return line should be cool( even have condensation on it) but never cold enough to freeze.Either use factory pressure settings or add just enough Freon until Ice melts. If unit has a high-side sight glass there should be no bubbles present. Do not overfill.
