Nordyne 626503R Auto Limit Switch Overview
The Nordyne 626503R is an OEM-grade automatic limit switch engineered to protect furnaces and heating systems from dangerous overheating conditions. Designed as a direct replacement for compatible Nordyne equipment, this auto-reset limit switch monitors supply-air or heat exchanger temperatures and interrupts the burner circuit when temperatures exceed the rated threshold — then automatically resets once safe operating temperatures are restored.
Key Features
- Temperature range: 245°F trip / 285°F auto-reset
- Automatic (AUTO) reset operation — no manual intervention required after cool-down
- OEM Nordyne replacement part — ensures proper fit and reliable performance
- Protects heat exchangers and furnace components from thermal damage
- Interrupts burner operation upon over-temperature condition
- SKU: 626503R
Application
The 626503R is designed for use in Nordyne-manufactured furnaces and air handlers where an automatic high-limit switch is required. It serves as a critical safety device, shutting down burner operation when the monitored surface or airstream reaches the trip temperature and restoring normal operation automatically once temperatures fall back within the safe range.
Why Choose an OEM Limit Switch?
Using an OEM-specified limit switch ensures accurate trip and reset temperatures, correct electrical ratings, and proper dimensional fit for your Nordyne equipment. Aftermarket substitutes may not meet the precise calibration required for safe, code-compliant furnace operation. The Nordyne 626503R delivers the reliability and accuracy your system demands.
