Why Choose an OEM Limit Switch?
Using a genuine Nordyne replacement limit switch ensures proper calibration, correct trip temperatures, and compatibility with your existing control board and wiring harness. An incorrectly rated limit switch can cause nuisance lockouts or, worse, fail to protect the heat exchanger — making OEM accuracy essential for both performance and safety.
