8402-046 OBSOLETE
- FAN & LIMIT CONTROL 11"
Bard part 8402-046 is an OEM fan and limit control with an 11 inch insertion length used on select Bard wall-mounted HVAC equipment to manage blower operation and provide overtemperature protection in heating modes. As a combined temperature-sensing safety and control device, it helps keep the supply fan cycling correctly while opening the circuit if abnormal heat conditions occur, which can prevent nuisance trips and protect heat section components. If your unit is short-cycling on heat, running the blower at the wrong time, or tripping a high limit, replacing the fan and limit control with the correct Bard OEM 8402-046 is a reliable way to restore designed operation, but be sure to confirm compatibility by matching the full unit model and wiring diagram before ordering.
