I have a 1979 Hatteras 43 DC; 2-16,000 BTU Cruisair units with three knob controls; 10 years ago pump wiring changed so that pump cuts ON-OFF when compressor cycles due to thermostat demand.  This past weekend on Sunday morning I awoke and found the temperature in the salon at 64 degrees (Columbia, SC).  When I turned the thermostat to a warmer setting nothing happened – compressor kept running.  I turned OFF the system and everything turned OFF.  I waited approximately 10 minutes,  turned the system back ON, and everything was running but still without responding to the thermostat.  When I turned the controls to FAN, the compressor and pump remained running.  I have noticed lately that the thermostat knob seems to be "loose" … it sort of wobbles.  Any thoughts?  Thanks for your help!  I will look here for your comments but you may call if you want.

Steve … my units are as follows:

Heat/AC:

      Manufacturer – Cruiseair            (16,000 btu each)

      Model No. Unit 1 – WFAH16  S/N: B98301 (Salon)

            Model No. Unit 2 – WFAH16  S/N: B98341 (Staterooms)

 

Can these units be upfitted with the digital controls and at what costs?  Thanks.

I had a used three knob control panel that I got from another Hatteras owner who had changed out his controls to the new digital controls.  I installed his three knob control panel and all is working well.  Thanks again for all your help.  By the way … I'm still interested in the cost to convert my two – three knob control panels to digital controls … probably this Winter.
