Bard HVAC 8402-114BX Thermal Cutoff failure to hold pressure during

failure to hold pressure during testing often indicates a compromised diaphragm

it triggers a shutdown if flue gases are not drafting correctly or if a heat exchanger failure occurs

Direct Replacement Logic: Effectively replaces the discontinued DMPR-RS201 without requiring hardware modifications

While replacement of an existing 212°F link is a standard field procedure

Bard HVAC 8402-114BX Thermal Cutoff failure to hold pressure duringThe Bard HVAC 8402 114BX is a critical safety component designed for precise over temperature protection in wall mount air conditioning and heating systems. As a veteran grade OEM replacement part, this 93C thermal cutoff functions as a non resettable high limit safety, engineered to open the electrical circuit if internal temperatures exceed 93C (200F). Frequently found in the electric heat sections of HVAC units, it acts as a permanent fail safe to
