Bard 8402-051 - Limit switch line break

Bard part 8402-051 is an OEM line break limit switch used as a temperature safety control in Bard wall mounted HVAC equipment. Rated 135-105, this switch is designed to open the circuit on abnormal temperature rise and then allow operation again after conditions return to normal, helping protect the unit from overheating and nuisance damage. If you are troubleshooting heat-related shutdowns or repeated safety trips, replacing the limit switch with the correct Bard 8402-051 OEM part helps restore proper safety operation and reliable cycling. Confirm your exact model and the required temperature rating before ordering to ensure correct fit and function.
