Amana-Goodman B1370195 Limit Switch Orifice sizing depends on theThe Amana Goodman B1370195 Limit Switch is a critical safety component designed for high limit temperature regulation in residential gas furnaces. Labeled as an L300 30F primary limit switch, this normally closed disc style switch is engineered to open the electrical circuit when internal plenum temperatures reach 300F, effectively shutting down the burners to prevent heat exchanger damage. Once the system cools by 30F (resetting at 270F), the
