Not much info there,bud.
Otis relay logic?
Check contacts are making,especially H relay?
Voltage is about 120 vdc?
Check for anything shortening out in the loop circuit?

Lots of variables there.

Had a electrician stick a fish tape into the back of a b base controller and melt the large rectifier in the back. I ordered a replacement and it wasnt that expensive. So if it the rectifer itself swapping it out isnt that bad.
