I have and issue now for 2 years that has prevented me from selling or trading off our Newell as the rear slide will not extend, read all the wires out to the control panel and limit switches all OK other than a compromised wire under the bed. Removed the logic board for slide 2 which is the rear slide and found a few of ground traces fried on the board itself, being a retired electronic tech I started tracing back to where the problem was and found one of the mini relays on the board defective and in the closed position, then found a few diodes open and one of the three 555 timer chip and a NPN transistor defective. Ordered and replaced all these parts and jumped the circuit board traces and still not working so called HWH they said to send it to them which I did in Sept of 2025 they said 4-6 weeks so I told them I would be in Florida after that time frame and not to ship back to me till our return end of March. They called yesterday and informed me that board is no longer available and they don't have one for sale. Does anyone here have one of these boards for sale? Or the entire control box? These boxes are only for Newell and there isn't a replacement. This is not only my problem this is a problem for all late model HWH Newell owners. If I can't find a board here my only choice is to purchase a PLC (personal logic computer) and retrofit it.
Sequence of operation for those who are interested.
Turn on or start coach. When you turn the slide key on there is a delay time (555 timer) so your seal can deflate, then when it illuminates you can start the extend or retract procedure either way the first thing is the locks activation to open after fully open there is a slight delay (555 timer) then the main hydraulic ram under the bed to either in or out and once the limit switch for totally in or out under the bed is made then there is slight delay again activates the locks to lock. Note my locks have NEVER worked in the rear and this unit has been out and sent to HWH prior to my ownership so somehow those limit switch activation has been removed from the sequence of operation.
