HWH Spacemaker Slide Motor Runs But Won't Extend: Complete RV Repair Guide
Every time we get heavy rain like those three days last week, my HWH Spacemaker hydraulic slide system motor runs but won't extend the slide out. The motor runs when I hit the extend button, but the slide absolutely will not move out. Everything else works perfectly - rear slide operates fine, leveling system works great, no blown fuses anywhere.
I've tested the extend solenoid and it's getting power, did an ohm test which showed 1.2 and open (which appears acceptable per the manual). I've already checked the converter box and solenoids and they look good. The safety locks are fully retracted so that shouldn't be the issue. I can hear the motor operating but there's zero movement on the slide itself.
I'm really hoping someone can point me in the right direction here. What are the most common causes when the motor runs but nothing happens? Should I be focusing on hydraulic leaks or is this still likely a solenoid problem even though it tested okay? …more
