8402-030 OBSOLETE
- Thermal Cut-Off 4K9218H
Bard part number 8402-030 is an OEM thermal cut-off (Thermal Cut-Off 4K9218H) used as a temperature safety in Bard wall-mounted HVAC equipment with electric heat, where it opens the circuit if abnormal heat is detected to help protect the heater assembly and wiring from overheating. When a thermal cut-off trips or fails, it commonly leads to loss of electric heat, nuisance lockouts, or repeated safety openings, so replacing it with the correct Bard 8402-030 is important for restoring proper heat operation and maintaining factory safety sequencing. Match by part number and confirm your unit model and electric heat kit configuration before ordering to ensure correct fit and temperature rating.
