Trane 4WCX3060A1000BA Serial #135010319L. Met with and confirmed work to be completed. Proceeded to roof unit and carfully removed and installed the new defrost control board and tested. I also removed to clean the entire blower motor and assembly, taking apart the wheel and motor and cleaned thoroughly and applied antimicrobial to treatment before reassembling blower assembly and putting all back together to further test. System is operating properly now.
