Bard part 8402-199 is an OEM 2-pole temperature limit control used as a safety in Bard HVAC equipment to help prevent overheating by opening the circuit when the sensed temperature reaches its fixed setpoint. This control is rated L150 with a 3.0 degree differential, making it a direct-fit replacement when your original limit is nuisance-tripping, stuck open, or out of calibration from age and heat exposure. If you are servicing a Bard wall-mount or packaged system and the unit is locking out on high temperature, replacing the limit control with the correct Bard 8402-199 helps restore proper safety operation and keeps the heat section protected when airflow or combustion conditions drift out of range.
