I can't get my jacks to come up last time out had to use "T" handles to get them up. all lights on panel work as they should. sprayed with WD-40 too!

I close or counter clockwise them and they do not extend pump sounds under load, all 4 retract, the odds of 4 solenoids ALL leaking is astronomical.
They CLOSE clockwise. Counter clockwise they open. OPEN them and see if all 4 jacks extend. IF they do, then all 4 solenoids are probably burnt out. BUT, you check for 12 volt power at each solenoid when either retracting or extending to verify the 4 fuses for the solenoids are not blown. What will burn out a HWH solenoid is IF it has power for more than 15 minutes. The solenoids are momentary (no more than 5 to 7 minutes at a time) coil solenoids. LONGER than that and they will burn up. A common reason to burn 1 or all 4 is when you try to retract and one jack does NOT fully retract but you can travel,so you leave it in STORE mode while traveling. After about 15 minutes all 4 solenoids will burn out IF 1 or more jack down lights stay ON. Once the last red down light goes out the retract timer shuts the system off. Doug
