the K19AT-48 is designed to withstand a maximum hot junction temperature of 1300°F (704°C)

Technician-Grade Reliability: Features non-PCB oil and a 1/4 inch quick-disconnect terminal design for efficient service calls and long-term field stability

Constructed from high-grade aluminum

Using a switch with a higher temperature rating than the original factory specification creates a fire hazard and risks cracking the heat exchanger

this unit ensures reliable switching for compressors

Nordyne 626279R Limit Switch the K19AT-48 is designed toThe Nordyne 626279R Limit Switch is a critical OEM replacement part designed for Intertherm, Miller, and Nordyne gas fired furnaces. This L140 40F high limit switch functions as a fail safe rollout control, utilizing a temperature sensitive disc to monitor heat exchanger conditions. When the internal plenum temperature reaches the 140? F trip point, the SPST (Single Pole Single Throw) circuit opens, immediately disconnecting power to the gas valve to
