Description
The Nordyne 1045337R is a factory-replacement high-limit switch engineered to protect Nordyne furnaces from overheating conditions. When supply air temperatures exceed the rated set point, this limit switch opens the circuit to shut down the burner — preventing heat exchanger damage and ensuring safe, reliable furnace operation.
Product Overview
Designed as a direct OEM replacement for select Nordyne furnace models, the 1045337R limit switch features a 225°F trip point with auto-reset functionality, meaning the switch will automatically restore operation once temperatures return to a safe level. The 3/4″ diameter housing and 2-stage configuration make it a precise fit for compatible Nordyne applications.
