HWH leveling problem
About 4 months ago, at the campground, my driver side HWH jack would not retract. I went to the solinoid and turned the screw as instructed in the manual. The jack retracted. Upon returning home, I cleaned it with WD-40. It would retract but slower than before. It was 5 minutes compared to 30 seconds on the passenger side jack. Again about 1 week ago, the same jack would not retract. So I cleaned it again, it retracted but again about 5 minutes. The jack springs are the old style, straight spring instead of the new style tapered.
Could this be the springs? Or something else? How can I troubleshoot the solinoid or the jack itself?
I had one service tech tell me not to use WD-40 but to use PB-Blaster to clean. Another tech at another shop told me not to use PB-Blaster but to use WD-40. I also heard that HWH recommends WD40.
Any opinions on what to use for cleaning? Thanks ...................
