Initial symptom - Left rear jack would not retract. It was locked in the "down" position solid, upward force on the jack base did nothing. Pressing "Store" on panel only retracted other three jacks. Opening "T" handle on the solenoid did nothing. Only when I opened the bleed plug at top of cylinder and released fluid did the jack springs bring up the jack. After 3-1/2 weeks (after I first called HWH), I received a call back from HWH. Walking me through, we discovered no 12 volts at the solenoid. HWH told me to check the fuse on the "silver" power box velcroed to the firewall. While I was able to squeeze my hand in to loosen the velcro, I was unable to maneuver the box to view the end of the power box due to the multiple wire runs and air ducting. At this point, I took the coach to a local dealership for them to work on the jack problem. They found a blown 10amp fuse on the power box and replaced it. Attempted to operate the leveling system again and blew the fuse again. They replaced the jack sensor and substituted another solenoid for the affected jack and said the jack extended and retracted. They informed me that I needed another solenoid. They contacted HWH and was told the solenoids were on backorder and not expected in for about three weeks. Last evening, I looked at listings of 1/2 dozen solenoids on Amazon and Ebay; they were all "ended". I called two RV places this morning within my 50 mile area and found three solenoids (old T-handle style) at one location and one at the other. I drove to one of them and purchased same for $210.00 (the other place wanted $277.00 for one). I delivered the solenoid this afternoon to where my coach is. Hope to know something tomorrow.
