PTAC malfunction

Troy A Burnett Feb 11, 2014 06:00PM EST

The unit (2yrs. old -Ramsond ptac kcd 45) will not heat or cool. The control panel on the unit lights up but all buttons are non-operational. What is the likely problem and how can I get it fixed?

You should try to reset the unit first by unplugging the unit for more than 60 seconds if this doesn't fix the issue than have your local HVAC technician check the circuit board communication
