S912-0049 OBSOLETE
- FAN & LIMIT ASSEMBLY
The Bard S912-0049 fan and limit assembly is an OEM control used on Bard heating-equipped HVAC systems to manage blower operation and provide over-temperature safety protection. In normal heating operation, this control helps bring the indoor blower on at the proper time and keeps it running long enough after the heat cycle to reduce short cycling, while the limit function opens the circuit if the supply air temperature rises beyond the safe setpoint to protect the heat section and ductwork. Because fan and limit controls are wired into the unit’s heat and blower circuits, matching the correct Bard part number and verifying the electrical connections and temperature settings against your unit wiring diagram is important for a proper repair.
