CC OTR Compressor
Had the CC OTR system tested for leaks, charged, and working when we were in Anchorage, Alaska. Everything seemed to be working fine on our way back but then we began having cooling issues. We are having a problem with the otr air on a 1995 Country Coach (96 conversion). The air temperature from the galley and bedroom began to fluxtuate from 60 to 50 to 45 and now has mostly guit cooling. Checking the air conditioner it seems the compressor tries to engage but after about 3 to 4 seconds, it stops for about the same amount of time. It continues in that fashion never completely engaging.
Anyone experience this problem or have any ideas?

sounds like its low on freon. Those usually have the condensing unit mounted up by the axle I have found lines leaking there several times
-
CC put those condensers in a bad place, I had one damaged from road debri and then later a leaking line as Jeff suggested.
-
Thanks for the info. Is that condensing unit and lines something I can get to thru the engine compartment or is it access from under the bus?
-
Not visible from engine compartment, must be accessed from under the coach…..

I guess I expected that. I will need to take it to a shop for repair and I understand that most automotive ac places can repair this. The one I am looking at does do quite a few motorhomes and some buses so it sounds like my best shot to determine what is going on.
Thanks to all for the help.

I think that vintage CC had the condenser located so it blocks access to the air dryer. Based on the cost to repair moisture damage from a pneumatic system that has not been maintained it might be a good idea to move the condenser coils out of the way, replace the dryer element and then deal with the AC problems.
Wouldn’t hurt to drain the tanks in succession to drain any moisture and to verify the proper operation of the protection valves as long as you are going to be under the coach.

Jim,
It’s mounted right in front of the drive axle, you can see it if you look under. (don’t crawl under without supports)

I had a similar situation with my CC OTR. Is was definitely the freon level and has been great since tested and recharged.The AC on my coach comes from under the bed and the galley cabinets as yours may. The lines are therefore long and difficult to reach. Mine has stayed charged but I may tackle replacing the lines this winter based on the age the coach.

Free advice George……..if it ain’t broke in this case, don’t fix it. Running new AC lines can be a very difficult job and because of their construction AC hoses have an incredibly long life. They will age but I think because most reside under the hood of a car where temperature extremes are the rule our coaches are generally easy on the hoses.
When the time comes to replace them you will know.
