Thank you sooooo much for your help. Today I had another unit that I swapped finger controller for lift and tilt. Lost code of T225, Now sometimes has L220, will lift for about 4 inches and stops. Sometimes will tilt forward and back. Then sometimes will give codes L220 L280 and L426. Have swapped controllers and seems to be the same. When you say to check connections between above noted pins. From which pot? I can read the numbers on both connectors and know what you are talking about. Is there a learn mode on this type of unit. Like a Raymond or Crown?

Again,
Thanks a million for your assistance. Here in Texas, very few of these units.

Sincerely,
David
