Description
The Nordyne 626435R is an automatic reset limit switch engineered to protect furnaces and heating systems from dangerous overheating conditions. Designed as a direct OEM replacement for compatible Nordyne equipment, this limit switch provides dependable high-temperature cutoff and automatic recovery to keep your system running safely and efficiently.
How It Works
This auto limit switch monitors supply-air or heat exchanger temperatures continuously. When temperatures reach the upper threshold, the switch opens the circuit to shut down the burner or heating element, preventing damage to the heat exchanger and surrounding components. Once temperatures fall back to the reset point, the switch automatically closes, restoring normal operation without requiring manual intervention.
