I have a 2004 3100se Maxum - 5k GenSet, Dometic
Marine Air Systems heat/AC unit. I think its a 16000BTU. I was getting ready to winterize the heat / AC system, when I turned it on. Unfortunatly, the unit did not engage. The digital control worked fine, and the fan kicked on, but the comprossor /
water pump would not active. The AC light stayed lit, even when I turned the temp up to 85. With it not kicking on, I could not run
antifreeze through it to winterize.
I then did the factory automated self test, by holding the
power button right when I hit the breaker. This did kick it on. I was then able to run
antifreeze through it to get it winterized.
When spring comes around, this is the first thing on my agenda to fix. Any thoughts as to why it would not kick on normally, heat or AC, but would with the self test? it was 66 degrees in the
cabin, 80 on the top
deck (campertop up) 55 outside with the a 10
knot wind.
Water temp was between 50-60 degrees.
Thanks in advance for your help!!!
