I believe I have the same type of softener as you but I don't have any of the manuals. The one I have, had problems with the microswitches, which I found replacments for through the grainger catalog #400 page 330 part number 3XG44 $2.73 each & 3XG45 $2.74 each quanity 2 each. I don't have any idea what part number 49A is but if it is one of the switches they are available through grainger for $10 or $12. Does your manual have a wiring diagram for your timer? I could sure use it! Thanks
