AC issue

Galley AC keeps freezing over in auto on my 2006 fleetwood bounder. Running on high seems to not be cooling but keeps the ice from building. What should I check?

Sounds like maybe low coolant if it is not cooling on high. You may also want to make sure the coils are clean as well.

Roof airs have an ice detector installed on the coils to keep them from freezing. many times these fall off from banging down the road. There are two types. one is a metal tip about the size of a toothpick end. It just wedges into the cooling coil. The second is a small metal canister about 1 and 1/2 inches round with a clip that clips over the copper pipe at the end of the cooling coil. (Use a tyrap on this type to keep it in place.) You access both of these by taking off the inner shroud of the A/C on the inside of the R/V.

Unless you have the correct tools and EPA Certification you can't check the refrigerant yourself.

Any AC supply company sells a piercing valve. It clamps around the cooling coil and pierces the copper line when screwed in. The one I usually used was a Supco bullet piercing valve part number BPV 31. It came with adapters for 1/4, 5/16, and 3/8 tubing.

Sorry, but the only thing those are good for is a return call because the o-ring seal leaked the refrigerant. The only ones I ever use is the solder on saddle valve. It is most likely charged with R22 and without EPA certification your not going to buy any. Without the certification it is illegal to possess.

Supco does not use a o,ring. They use a sealant strip on the saddle valve. I used one on my 1978 Argosy and one on my daughters bedroom window AC. They both lasted almost ten years. I don't know how much longer they lasted, because she sold the house and I sold the motorhome after almost ten years.
