Arrived on site to diagnose system that is not shutting off blower motor. Client stated he just had a technician come out yesterday as client got sensi predict system installed on both his units. After doing so unit will not shut off blower for downstairs system. Got in attic and found one cover off unit and client stated he had just taken off cover and didnâ€™t want to try and fix himself even though client has done reports of his units. Inspected unit and electrical compartment and connections. Found system to not be tripping any error codes. Inspected electrical wiring and found cooling wire to not be on right terminal. Wired wires back up correctly and systems was operating properly. Cycled heating and cooling to ensure system operating properly and that fan is shutting off. Recommend adding surge protectors on unit to protect for electrical surges and power outages that can damage or even short out systems and components. System is operational upon departure.
