Roof A/C maintenance
Posted: Thu Sep 03, 2020 9:47 am
Hello Safarifriends,
Having recently purchased my '01 Zanzi 3646 I will probably pester the group with some questions for awhile.
I am interested in doing some preventive maintenance on the two Dometic roof airs in the coach and aside from obviously cleaning the grill and filter inside the coach want to perform some other routine maintenance up top. I have seen suggestions to use Nu-Calgon 4171-75 Evap Foam No Rinse Evaporator Coil Cleaner, let soak for a bit and then rinse with a spray bottle with water. Furthermore, it was suggested to lightly lube the fan shaft with 3-in-1 oil. Seems like that is pretty much "it" in a nutshell?
Do you ever need to have these roof airs recharged with refrigerant? I would think as long as you have cold air that it isn't leaking so never necessary?
Tips, tricks, do's, dont's?
Regards,
