My Marine Air System 16000 BTU unit, Serial#87K11967-11D is not producing full heat in the heat mode. It appears to be working in AC mode. The suction line temp is hot at 204F and the discharge is 60F. The seawater temp is 55F. The compressor is hot at 125F. I cycled the reversing valve many time thinking it may be hung up. I can hear the soilinod clicking and the sound of the reversing valve shifting.

When the unit runs in cooling mode the suction is 22.7F and the disch is 76.5F with the compressor at 110F.


I have another C16H on the boat and in heat it runs 145F suction, 60F disch and 47F compressor temps.

Any help would be appriciated.
