Description
The Nordyne 1045338R is a factory-replacement limit switch engineered to restore safe, reliable operation in Nordyne-platform furnaces and heating equipment. Designed as a direct OEM replacement, this limit switch protects heat exchangers and furnace components from overheating by interrupting the circuit when supply air temperatures exceed the rated setpoint.
Product Overview
This limit switch features a 3/4-inch disc sensing element and single-pole switching action. It is rated to open on a temperature rise, activating at 225°F to shut down the burner circuit before unsafe temperatures are reached. The auto-reset function allows the switch to restore normal operation once temperatures return to a safe level, minimizing service interruptions and nuisance calls.
