Description
The Nordyne 626494R is a genuine OEM automatic reset limit switch engineered to protect furnaces and heating equipment from dangerous overtemperature conditions. Designed with a 240–280°F operating range, this limit switch automatically opens the circuit when temperatures reach the upper threshold and resets once safe operating temperatures are restored — providing reliable, hands-free protection without the need for manual intervention.
Key Features
- Automatic (auto) reset operation — resets once temperature returns to safe level
- Operating temperature range: 240°F (open) / 280°F (close)
- Genuine Nordyne OEM replacement part
- Designed to prevent furnace overheating and heat exchanger damage
- Direct drop-in replacement for compatible Nordyne, Frigidaire, Gibson, Tappan, and affiliated brand equipment
- Durable construction for long-term reliability in residential and light commercial heating applications
Application
This limit switch is a critical safety component in forced-air furnaces and air handlers. When airflow is restricted or a fault condition causes temperatures to rise beyond safe limits, the 626494R opens the circuit to shut down the burner and prevent equipment damage or fire hazards. The auto-reset function restores normal operation once the unit cools to a safe temperature.
