Nordyne 626418R Limit Switch maintaining the integrity of theThe Nordyne 626418R Limit Switch is a critical OEM replacement part engineered for precise thermal regulation in HVAC systems. As an L150 20F automatic reset limit switch, it functions as a primary safety control, monitoring the internal plenum temperature to prevent heat exchanger damage. When the temperature reaches the fixed 150? F trip point, the switch opens the electrical circuit to shut down the heating element or burner. Once the system cools
