I had the same issue with the jail bars not coming down, My fix was to upgrade to software version 14, remove the small coil and unwind 225 winds (started with 100) to make the coil stronger and cut 2 rounds off the coil spring and it works like a charm. Coil resistance was 14 ohm to start and 8 after removing the 225 winds. I ordered a new coil and spring as well, but got it fixed without having to wait for parts, which is always a plus. Hope this helps someone
