Ok I’m starting another thread about my air system saga that is hopefully less convoluted.  First off I got my 120v compressor back on line.  It was two separate problems.  One, the one way check valve was bad and two… the unloaded solenoid was bad. It is working now (aside from occasionally blowing the 20 amp breaker).  My coach has a raised bed slide on the drivers side and a dropping floor slide on the passenger side.  Both slides have vacuum systems added to the regulators and two way valves in the lower compartment that switched between regulated pressurized air to fill the seals and vacuum to deflate them.  I found one (drivers side - same as was having loud seal leak before ) had a vacuum pump that was blown apart.  During trouble shooting the system , I found a piece of teflon tape stuck in the 2 way Parker valve not allowing the valve to completely close in either direction.  The valve was open to the vacuum pump during pressurizing the seal and it caused the pump to blow apart.  I repaired the valve and the replace the pump and thought all was well…. Until this morning.  We spent the night in Reno on our way to California for a late thanksgiving.  Woke up this morning and fire up the 60.  After few seconds I started to hear air hissing inside the coach.  It was coming from under the head board ( just like before).  I ran outside and heard air hissing from the seal regulator (drivers side again) in the lower compartment an the passengers side.  The regulator was venting heavily, but the pressure read 70 psi.  I ran over to the drivers side seal and heard the air hissing (yes over the sound of the engine).  I ran back inside and shut the engine off and stabbed the brake several times.  The hissing from the rear finally stopped. ( I also learned my low air alarm is not working.)  Anyway after I bled the system down with the brake I fired it up again and all was fine???? What the heck.  It was below freezing so wondering is some check valve may have froze up.  I’m totally confused!!! Any ideas?
