Carrier HH18HA141 Limit Switch 340793-762 preventing liquid slugging at theThe Carrier HH18HA141 Limit Switch is a critical OEM safety component engineered for precision thermal monitoring in Carrier, Bryant, and Payne gas furnaces. As a normally closed SPST disc style switch, it serves as the primary high limit defense against heat exchanger overheating. This L140 40F limit switch is designed to automatically open the electrical circuit when internal plenum temperatures reach 140F, effectively shutting down the gas valve to
