Relay went bad Part# 155031110 and could not locate locally everyplace said obsolete and no replacement said I must have old well. Was installed in 2002, finally a service guy was at b-b sales only and he gave me one but I now want a replacement and I have found a few on line around $50. What is in the new 1.5 hp Franklin boxes then and why can't I switch to that or do I need to buy complete box if so I still want to know what is in them. I just want to be ready the next time I need parts. My box says relay 155031110 or 155031102. Thanks.
