Air pump won't shut off

Our monaco has air bag levelers, on our last trip the pump came on in the middle of the night and would not shut off. Every couple of minutes the excess air would dump. I pulled the fuse to the pump to get it to shut off. I put the fuse back in at home and does the same thing, any ideals on how to correct this problem. Thanks.

    Agree. Since the system is dumping the excess air the pressure switch that turns the pump on/off has failed and is stuck in the on position. Easy fix if you have the skills. If you know where the switch is first try giving it a whack with a mallet just to make sure it's not stuck.
  • It could as simple as the pressure switch controlling the compressor. Been there done that.
  • I think I'm having the same problem. There is a pump that comes on every 10 minutes or so just for about 3 seconds. The noise is coming from the front wheel area.

    I have turned off our leveling system and it still makes the noise. It doesn't matter if I have the leveling jacks down or if we are leveling on the air bags.

    I'll have it checked out when I get the chassis lubed in a couple of thousand miles.

  • Sounds like you have an air leak at one of the valves attached to the pump. They're usually mounted above the rear axle although Monaco started putting them up front so as not to disturb your sleep if it comes on in the middle of the night...time for some soapy water solution on the pump itself...Dennis
  • No it stays level pump just runs, ill give that a try to see if the pump shuts off .

    After my system auto air levels, I push the circle button (bottom left) that shuts the system off. Even after a month it's still level so no need to leave the system active. While this does not solve your problem, it should keep the 12V air pump from coming on. Are any of the yellow lights on... front, L/R sides, or back?
