• Thermal Cut-Off G5AM0400141

Bard part number 8402-027 is an OEM thermal cut off (often listed as 8402-027BX) used as a one time safety fuse link that opens the circuit if an unsafe overtemperature condition occurs, helping protect critical components and wiring in Bard wall mount HVAC equipment. This thermal protector is specified at 141C (286F) and is typically installed in the unit wiring where it can sense abnormal heat rise; once it trips, it must be replaced rather than reset. If you are troubleshooting a no heat or no operation condition, confirm the root cause of overheating (restricted airflow, failed motor, dirty coil, or electrical issue) before installing a new 8402-027 to prevent repeat failures and ensure proper fit to your Bard model and serial range.
