Hi,
I have a Carrier heat pump with a gas Carrier furnace for backup. I think the unit is about 13 years old. I noticed that my outside condenser was starting to ice up. I figured that maybe I was looking at it before the defrost cycle. Today when I came home I noticed that the condenser outside was extremely iced up with the ice and frost about 3/4" thick on the outside of the unit. Surprisingly it was still making heat. I turned off the system and scraped off the outside frost. Then I turned on the AC to try to defrost the coil manually. I went outside to watch the condenser and I noticed that the the fan of the condenser turned on for about 5 seconds and then shut right off. I tried turning the unit on and then off again, and waiting but the condenser did the same thing. I'm wondering if it could be a relay issue or a defrost thermistor (which I think means the whole board has to be replaced). Not sure. but there isn't an options for turning on the defrost cycle manually. The furnace is a 58MVP, the condensing unit outside is a 38YDB. I had the unit checked last year and the refrigerant was at a normal level. And the unit is not throwing any codes. I did try to turn the heat pump back on for heat and no such luck but thankfully my furnace is working so I do have gas heat. Any help is appreciated. Not sure how to change profile info but I live in NC now not NY.
