Chester,
Sounds like your 12V compressor is suffering from lack of use. Using it will loosen it up, or at least it has mine. Your 12V compressor should come on around 30 psi and shut off about 55 psi. It does run for a shorter time because it is only filling the small air storage tank that is located in the right drive wheel well. The 12V compressor only services the low pressure air systems for your slide seals, air toilets, air dump valves, and air pocket doors. I would not advise raising the air pressure on the 12V compressor.

The 110V compressor fills all 10 air tanks on your coach, including the one in the right drive wheel well that the 12V compressor fills. It comes on at 80 psi and shuts off at 110 psi. It does run longer, but it is filling many more air systems and larger air tanks.

If you take the covers off the pressure switches you should see a label with the pressure switch specs.

Hope this is helpful............................

Finally got got my 12v compressor to work.
Started with 10a fuse and was blowning it! changed to 15a and still was blowing iT1

Finally today I put 20a and its started to working ! its starts around 30psi and goes of at 55-57psi so happy! I was event able to empty our dump tank, it took some time to build planty air , but was able to use it. Looks like 20a fuse might just do it! we will see!
Happy Holidays everyone!!
