Product details
Description
The Nordyne 626619R Limit Switch is an OEM bimetallic thermal safety component designed for forced-air heating and HVAC systems. Built to monitor internal plenum temperatures, this single-pole open-on-rise switch ensures safe heating cycles by automatically interrupting electrical continuity if the surrounding air becomes excessively hot.
It opens at 140 degrees Fahrenheit to shut down burners and prevent hazardous overheating, then automatically resets by closing at 100 degrees Fahrenheit once the component cools down, restoring normal blower operations without manual intervention. Featuring a durable phenolic body, flanged mounting bracket, and standard quick-connect spade terminals, this replacement part provides reliable temperature regulation for compatible heating units.
How to use
- Ensure power to the HVAC system is completely turned off before servicing.
- Remove the access panel to locate the existing thermal limit switch.
- Disconnect the electrical spade terminals, unscrew the mounting bracket, and replace it with the new Nordyne switch.
- Secure the screws, reattach the wiring terminals, and restore power.
