OEM vs. Generic

Choosing the OEM 20162906 guarantees the exact trip temperature, mounting bracket, and terminal spacing the control board expects. Aftermarket limit switches with the wrong set point can cause nuisance lockouts or, worse, fail to protect the heat exchanger. For a safety-critical part, OEM is the recommended choice.

Installation Difficulty

Easy (2/5). A two-screw, two-wire replacement that most homeowners can complete in under 15 minutes. Always disconnect power and gas before servicing, and confirm the part number matches your old switch.
