The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM safety control designed for AMEC800805CXAA gas furnaces. This normally-closed thermal limit opens the control circuit if it senses excessive heat, protecting the heat exchanger and blower assembly from overheating. It is a direct-fit replacement that matches the original trip temperature and terminal configuration for reliable, code-compliant operation.
Our OEM option is the exact Goodman-specified part with a factory-calibrated trip point for guaranteed fit and safety performance. The Generic equivalent offers a budget-friendly alternative built to comparable specifications, ideal for out-of-warranty repairs where cost matters most. Both carry the correct temperature rating for this furnace.
Difficulty: Easy. Disconnect power, remove the two mounting screws, transfer the spade connectors, and reinstall. Most DIYers complete this in under 15 minutes. Always verify power is off at the breaker before servicing.
