The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM safety control engineered for the Goodman/Amana ACVC960403BNAA gas furnace. This thermally activated high-limit switch monitors heat exchanger and blower-compartment temperatures and opens the control circuit if the furnace overheats, protecting the equipment and your home from unsafe operating conditions.
Color-coded light blue to indicate its specific trip and reset temperature rating, this auxiliary limit is a direct-replacement part. Installing the exact factory switch ensures the furnace's safety logic behaves precisely as designed — generic or mis-rated switches can cause nuisance lockouts or, worse, fail to trip.
The OEM 0130F00038 is built to Goodman's exact trip temperature and mounting footprint, guaranteeing correct fit and safety performance. Generic universal limits may differ in set point or terminal orientation, requiring rework and risking improper protection. For a safety-critical component, OEM is strongly recommended.
Easy (2/5). A two-wire, single-fastener swap for anyone comfortable working inside the furnace cabinet. Always shut off power and gas before servicing. If you are unsure, consult a licensed HVAC technician.
