My salon ac fan motor died on me. I had an ac tech (non marine, friend in the HVAC business) check it out and he determined the motor needs to be replaced ( it definitely wasn't blowing, condenser was running, he ruled out capacitor). I called Dometic supplier down here and got a price of $620 for a new blower (parts only). This seems really high (unit is a marine air 7000btu model VCD7k/2) considering an entirely new marine air 7k unit is only $1200. Question is how difficult is replacing an entire unit and is it worth the extra money to replace a 6yr old system.
