Thanks for the link. I'll start 'sifting' thru the Troubleshooting section. Got a blurb thru the mail from HWH: "Turn ON system to see if a red light is indicating a jack down. If so, go to the jack & make sure it is retracted. If so, will unplug the WR SW & see what happens & then check the WR SW". I never was good at code! Are they talking about a wiring switch?
Doxie and Doug--I'll look at your 'angles' when we travel next Sat. to LA. Thanks. jim
EACH Jack has a down magnetic switch on top the jack cylinder. IF the jack is inded fully retracted and THAT jack red down light is ON, you unplug that switch on top the jack and the light goes out. VERY RARE for a HWH down switch to fail. There are 3 wires on top the jack if Automatic(computerized) Leveling. the down switch has 2 wires and just unplug it. The other is a single wire pressure switch, do not unplug it. I am a HWH factory trained tech and I also am confused by the WR. It obviously refers to the Down switch, but what WR means, HWH will have to explain. They may have meant to write WS which is what the switch is called--- Warning Switch. Doug
Doug---I've had several suggestions about checking the fluid level. If it's not 1" from the top, can I get away with using Dexron III or is it pretty mandatory to use HWH Specialty Hydraulic Oil? I'll print out your technique and then see if that will, at least, turn off the chime and the red light. I assume then that a new down switch will have to be installed IF that is the cause. I've made an appointment @ Aloha RV in Albuquerque just in case.....Thanks for your help. Jim
