Description
The Trane CNT4823 is an OEM limit switch engineered to safeguard heating equipment against unsafe operating temperatures. Designed as a direct replacement for compatible Trane systems, this auto-reset limit switch automatically restores normal operation once temperatures return to a safe level, eliminating the need for manual intervention after a nuisance trip.
How It Works
The CNT4823 monitors the temperature within the heat exchanger or air plenum and opens the control circuit when the sensed temperature reaches the 200°F setpoint. Once the equipment cools below the reset threshold, the switch automatically closes, restoring normal operation. This auto-reset design reduces service calls caused by manual-reset lockouts while still providing essential overheat protection.

Why Choose an OEM Trane Limit Switch?
Using a genuine Trane replacement limit switch ensures proper fit, accurate trip temperature calibration, and reliable performance. Aftermarket substitutes may not meet the exact electrical or thermal specifications required by your Trane system, potentially voiding warranties or causing improper operation.
