Mounted on the heat exchanger or blower deck, this thermostatic switch monitors supply-air temperature and opens the burner circuit if the furnace overheats — protecting the heat exchanger from cracking and preventing unsafe operation. A failed or drifted limit switch is a leading cause of short-cycling, no-heat calls, and nuisance lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162901\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-temperature limit (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Safety control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on rise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Goodman VCES960403BNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Direct-fit OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip and reset temperatures on a limit switch are safety-critical and model-specific.

This \u003cstrong\u003egenuine Goodman OEM limit switch\u003c\/strong\u003e is calibrated to the factory setpoint for the VCES960403BNAA, so the furnace's safety logic behaves exactly as designed.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy–Moderate (2\/5).\u003c\/strong\u003e The switch is secured by two screws with quick-connect terminals.
