Bard part 8402-141 is an OEM two pole temperature limit control used as a safety cutoff in Bard HVAC equipment, including wall mounted units with electric heat. Rated L160-7.0, it is designed to open the circuit if the internal temperature reaches 160 degrees F and then reset after a 7 degree F drop, helping prevent overheating and nuisance damage to heaters and surrounding components. If your unit is tripping on high limit or has an intermittent heat shutdown, replacing a weak or out of tolerance limit control with the correct Bard 8402-141 is a straightforward way to restore proper safety operation. Confirm mounting style and wiring match your unit model and serial before ordering.
