Nordyne 626599 160F Inducer Limit Switch Manual Reset

The Nordyne 626599 is an OEM inducer limit switch designed to protect furnace heat exchangers and combustion assemblies from dangerous overheating conditions. Rated to open at 160°F, this manual-reset (M/R) safety device monitors the temperature at the inducer assembly and interrupts the control circuit when an unsafe temperature threshold is detected — preventing equipment damage and potential hazards.

Key Features

• 160°F trip temperature for precise high-limit protection
• Manual reset (M/R) operation — requires deliberate technician reset after trip event
• Designed for use on Nordyne-platform furnaces and air handlers
• Mounts at the inducer blower assembly for accurate temperature sensing
• OEM replacement part for reliable, factory-spec performance
• Helps prevent heat exchanger damage caused by restricted airflow or inducer failure

Application

This limit switch is a direct OEM replacement for Nordyne-brand furnaces and is engineered to integrate seamlessly with existing control boards and wiring harnesses. The manual-reset design ensures that a qualified HVAC technician investigates and resolves the root cause of any overtemperature condition before the system is returned to service — an important safety feature that prevents repeated nuisance trips from masking underlying issues.
