Re: AC defrost

Really wish I could help. Worked on a/c systems thousands of time but they were air cycle machines with no freon. Is the evaporator freezing up resulting in no air flow? Why else would you need to defrost it? If so you have to much humidity. Turn the system off and let the ice melt then run the system on low speed and let the system slowely dehumidify the air across it. Might take some time. <br /> Wish I could be of more help but it was only a few years ago i discovered those big boats were not pumping the bilge but pumping water over the condenser. regards fred

Re: AC defrost

Hey, on reflection I was really out of my league on trying to respond to that one. Maby there is a low air flow sensor that turns on an elect. element to heat the evaporator. What do I know. Will try to be more judicious before i respond again. Think i will go grab another beer. fred
