I have an acorn 180 that I am working on. I have programmed it multiple times but when it comes out of programming mode it wants to tilt really fast until a number 4 displays. The number 4 means it is out of level and so I manually level it. I can put it in programming mode again and it will operate and level itself but as soon as I put it in run mode it will tilt. I have adjusted the pentionemeter to set it level to no avail. Any suggestions? Could it be a bad encoder for the leveling motor? If so, why does it work in programming mode? Could it be that my reprogramming of the lift isn’t saving? I’m at a loss on this one. Any help would be awesome! Thank you.

Are you doing a full re-programm from scratch not just a datum reset?
I’ve had this and a full re-program sorted it

Yes you have to do a complete reprogram after adjusting the level pot

After a lot of research and trial and error, the problem was the encoder for the drive motor. The encoder counts the number of times the shaft rotates giving the stairlift computer the exact location of the chair on the rail. This allows the computer to know how to tilt the chair. Since the drive encoder was broken, the computer was confused and would tilt it randomly. By contacting the manufacturer of the encoder, US Digital, I was able to buy it for around $85 USD. Incidentally, the part for the leveling motor and the drive motor are identical. The part number for my particular Acorn 180 model was E5-32-375-I-S-H-G-B. It was fairly easy to replace. Make sure to take a few pictures when uninstalling the old encoder so you will have something to reference when installing the new one. When replacing, make sure to use the spacer tool when pushing down the metal/plastic optical ring so that it has the correct amount of spacing. Also, use a long ratchet socket to evenly tap down the ring to the correct position. Once I replaced the encoder, I was able to reprogram the stairlift and it worked great! Thank you for all of your help on this forum!
