Coleman Supermach repair
I know I'm not the first one to have this problem. Please help!
My '89 Excella has a Coleman Supermach. Cooling has been diminishing. I have cleaned both coils; cleaned drain lines,etc. I had a port installed and added R22. It now cools great, only problem is that it trips the 20A breaker after about 15 minutes. I have replaced the AC breaker, main 30A breaker AND the the power plug to the Airstream.
I don't know what else to do, other than buy new. And, then, I cannot decide between Mach 8 and dometic penguin. I am in New Orleans for the next 90 days and it is hot as can be.
