The Bard 8402-003 Fan and Limit Control 5 inch is an OEM temperature-sensing control used in Bard wall-mounted HVAC equipment to manage blower operation during heating and provide high-limit safety protection if the heat section gets too hot. It helps bring the fan on at the proper time, shut it off after the heat cycle, and open the limit circuit on overtemperature to protect the unit. When replacing this control, match the insertion length and wiring connections to your existing part and verify compatibility by model and serial number to ensure proper operation and safe temperature control.
