Hey guys for the one that deal commercial, i need little input from you guys, i am working on this trane chiller and i found circuit one on compressor it had a welded contactor and it trips yhe alarm and circuit two comes on. But doesn’t bring on the fan , so it goes off on head , but then it goes on alarm and circuit 3 comes on and brings on the fan then. I trace it out and i feel it could be the contact relay in the compressor module. Did any of you guys had gone through this problem. Any input would be appreciated thanks guys.
