Hi, model number is 7FGU25, serial number is 81130. Replacement regulator part number is 23530-U2201-71. I'm trying to find out if this is plug and play or if it needs adjusting after install. I have no experience with this, any help would be greatly appreciated. Some stores tell me that without a small tag on the existing regulator I risk buying the wrong part, but I cannot see a tag. The only number stamped on it are: Aison W.P.250P.S.1 (may be 8.I instead of S.1) and W.C.0311 L8S. The lift has been running rough since I bought it about 2 months ago, so Im not even sure this is the correct regulator. Thank you so much!!
