Ac control

[STEAMBOAT99]

I own a 2007 Itasca Ellipse IKR 40 FD
My hot water heater control on outside firewall will not shut off the hot water coming to my unit when on AC or MAX AC I can pull it down by hand and it shut off hot water and I get plenty cold air some of my vacuum lines had deteriorated and i replaced the ones as far as i could but fill like its still leaking behind dash so my question is has anyone ever got in behind the AC/Heater control I would like to run all new vacuum lines and maybe a new ac/heater control just not sure a old man can tackle that but I am sure I will get some good answers like I always have THANKS IN ADVANCE STEAMBOAT99

Sounds like your dash AC system is an Evans unit , by the vacuum controls .

I had my control out recently and found Evans parts tags on the control head and vacuum harness . My Ranco valve ( water valve ) is electronic so my harness number wouldn't help you.

Comfort Aire , handles Evans repair parts and they list a couple of vacuum harnesses , could be they have what you need.
Have a look around for any decal or indication your system is Evans , most vacuum controlled systems are ; mine was obvious .
