Description
The Nordyne 626456R is an OEM automatic-reset high-limit switch engineered to protect Nordyne heating systems from unsafe operating temperatures. When supply-air or heat exchanger temperatures exceed the upper threshold, the switch opens the control circuit and shuts down the burner — then automatically resets once temperatures return to a safe level, minimizing nuisance service calls.
Key Features
- Temperature range: 105°F to 135°F (open on rise)
- Automatic (AUTO) reset — restores operation once temperature drops within safe limits
- Direct OEM replacement for compatible Nordyne furnace models
- Protects heat exchanger and blower components from thermal damage
- Reliable bimetal disc sensing element for consistent trip accuracy
- Quick-connect terminals for straightforward installation
Application
Designed as a direct replacement limit switch for Nordyne-branded furnaces and air handlers. Always verify compatibility with your specific model number before installation. Consult the equipment wiring diagram and service manual for proper mounting location and terminal orientation.
Why Choose OEM Parts?
Using genuine Nordyne replacement components ensures the switch is calibrated to the exact temperature thresholds required by your equipment, maintaining safe operation and preserving equipment warranty compliance.
