Bard part number 8402-148 is an OEM manual reset high-limit safety switch assembly (L325-30) used as a backup limit on select Bard FLR series oil-fired furnace cabinets. When excessive cabinet or heat section temperature is detected, this enclosed limit opens to interrupt the heating circuit until the unit cools and the switch is manually reset, helping protect the furnace and surrounding components from overheating conditions. If you are replacing 8402-148 due to a tripped or failed limit, confirm the root cause (airflow restriction, blower issues, or venting problems) and verify the exact furnace model and wiring match before installation, since this control is a critical safety device.
