HWH Slide issues need help - sunsetrv - 10-27-2026

2002 45 3 slide Coach # 628
I have sent my box into HWH 2 times. 1st HWH send in was to have a complete inspection and rebuild what was necessary due to multiple faults and preventative maintenance. Installed box from returning from HWH I went from everything working except living room floor and living room slide would come out and not come back in. No power or light on for living room board. Out goes the entire box again because just removing the board is not enough. Spend more money and reinstalled box and now living room slide is completely non op light still does not come on and now drivers bed slide is non op as well. Back on the horn with HWH and they indicated that Newell changes some of the components in the box from there preset control board settings. I have heard of a strawberry that could delete all the old control boards and would solve my problems. Could someone lead me in that direction please.

Ok, breathe deeply.

I am sorry that HWH and Newell are pointing the finger at each other.

Your best bet is to make an appointment and take the coach to HWH in Moscow IA. The in person experience is far better than their remote interaction.

Was everything working BEFORE you sent the boards to the HWH the first time?

When you say the lights will not come on, do you mean the yellow lights at the room keypad?

Have you checked the ground wire, I think it is 6900 or 7900, that is connected to the parking brake pressure switch. HWH requires that wire to make to ground or NOTHING will happen. The purpose is to prevent accidental room deployment unless parked.

We are happy to help you with our limited knowledge, but it will require small steps to narrow the problem. Some folks don’t have the patience to deal with that.

There has been some discussion about replacing the HWH control system with a custom programmed Rasberry Pi computer. It is discussion right now, NOT an available solution.

Where are you located?
