Description
Product Overview
The Nordyne 626612 is an OEM auto-reset high-limit switch engineered to protect furnaces and heating systems from dangerous overtemperature conditions. With a switching range of 135°F to 165°F, this limit switch automatically interrupts the burner circuit when supply-air temperatures exceed the set point, then resets itself once temperatures return to a safe operating level — eliminating the need for manual intervention during normal operation.
Key Features
- Auto-reset operation — restores normal furnace function once temperatures drop to safe levels
- Temperature range: 135°F – 165°F
- OEM Nordyne replacement part — ensures proper fit and reliable performance
- Protects heat exchanger and furnace components from thermal damage
- Direct replacement for compatible Nordyne, Frigidaire, Gibson, Tappan, and affiliated brand furnaces
- Durable construction for long service life in residential and light-commercial heating applications
Application
Designed as a direct OEM replacement for Nordyne-family furnaces, the 626612 limit switch is a critical safety component that monitors supply-air temperature. When the furnace overheats — due to a dirty filter, blocked airflow, or blower failure — the switch opens the burner circuit to prevent damage. Its auto-reset design means the system can resume normal operation once the fault condition is resolved, making it ideal for both service replacement and preventive maintenance programs.
