For those of you with an older Monty, ours is a 2001, that have DeWald (now called Power Gear) slide mechanism/pump, this may apply to you. Our slide motor was working intermittently and then would continue to run for 2 to 5 seconds both when putting slides in and out. Bob called Power Gear and they immediately knew the problem was faulty solenoids. They sent new solenoids (not for free, of course), Bob installed them today and the slides work like new. He said they weren't hard to change, just hard to get at. It is so nice to have a "handy" man
around the house!!
