Trane CNT1662 High Limit Critical Safety Protection: Interrupts theThe Trane CNT1662 High Limit is a critical safety component designed for precise thermal regulation within furnace and air handler heat exchangers. Built with an L250F SPST NC C High limit configuration, this switch acts as a failsafe by monitoring supply plenum temperatures and interrupting the 24V control circuit if levels exceed the 250F threshold. This immediate shutdown of the gas valve helps prevent structural damage to the primary heat
