8402-031 OBSOLETE
- Limit Control 155-130
Bard part number 8402-031 is an OEM limit control (often listed as a limit switch) used as a temperature safety in Bard HVAC equipment to help protect the unit from overheating. This control is designed to open the circuit at 155 degrees F and reclose at 130 degrees F, which helps safeguard heaters and internal components during abnormal temperature conditions. When a Bard unit is tripping on high temperature, short cycling on heat, or showing heat-related safety lockouts, replacing a worn or out of calibration limit control like 8402-031 can restore proper safety operation, but always confirm the exact part number and mounting style against your unit model and wiring diagram before ordering.
