Re: Freon Capacity of the A/C system ?
Reply #3 –
One of the POs converted it. It is clearly marked R134A on the (replacement) Sanden compressor.
Come to think of it, that's one place I forgot to check for system capacity! Thanks for the idea, Brett.
Here is the value of receiving good records when you buy a pre-owned coach:
According to the "Maintenance Book" I got with our coach, on 6/12/2002 at 133,387 miles, 2nd owner Andy Kissinger had the dash A/C converted from R12 to R134. According to his notes, they used 72 oz. of refrigerant.
Then, on 10/08/2010, 4th owner John K. replaced the dryer, had system flushed, and recharged with "R134 x 6". I assume that refers to 12 oz. cans, which would also be 72 oz. John also had the system worked on a couple more times in 2012. He told me he had put a lot of time and effort into getting the dash air working, which it did when we purchased the coach from him in 2013.
ANYWAY, now at least I have a quantity number to reference when discussing the present problem with a tech.
