Nordyne 626600 Auto Limit Switch Overview
The Nordyne 626600 is an OEM auto-reset limit switch engineered to protect furnaces and heating systems from dangerous overtemperature conditions. With a temperature range spanning 110°F to 150°F, this limit switch automatically monitors heat exchanger or plenum temperatures and interrupts the heating circuit when temperatures exceed the safe operating threshold — then resets automatically once temperatures return to normal operating range.
Key Features
- Auto-reset operation — restores normal function once safe temperatures are reached
- Temperature range: 110°F to 150°F
- OEM Nordyne replacement part (SKU: 626600)
- Designed to protect heat exchangers and furnace components from thermal damage
- Direct drop-in replacement for compatible Nordyne, Miller, Frigidaire, Tappan, and affiliated brand furnaces
- Reliable bimetal sensing element for accurate, repeatable temperature response
Application
This limit switch is a critical safety component in forced-air furnaces and air handlers. It is mounted on or near the heat exchanger and opens the control circuit if temperatures rise above the set point, shutting down the burner to prevent equipment damage or fire hazard. The automatic reset feature eliminates the need for manual intervention once the unit cools to a safe temperature.
Compatibility
- Compatible with select Nordyne furnace and air handler models
- Verify model number and wiring configuration before installation
- Consult equipment service manual for proper mounting location and orientation
