The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a factory-original secondary safety control for the Goodman/Amana AMH81005CXBB gas furnace and compatible 80% AFUE models. Mounted near the blower compartment, this auto-reset snap-disc guards against overheating in the blower/cabinet area — a backup to the primary limit that shuts down the burner circuit if temperatures climb outside the safe range, protecting the heat exchanger and surrounding components.

Specifications

Type: Auxiliary / secondary limit switch, snap-disc (normally closed)
Color code: Light blue (factory trip-temperature identifier)
Reset: Automatic — recloses when temperature normalizes
Circuit: 24VAC control interrupt
Fits: Goodman/Amana AMH81005CXBB and related furnaces
Part number: 0130F00038 (OEM)

OEM vs. Generic

The light-blue color code identifies this switch's specific factory trip temperature — installing the wrong disc value causes nuisance trips or unsafe operation. The OEM 0130F00038 guarantees the correct calibration and bracket. Because this is a safety limit, OEM is the recommended choice over universal snap-discs.

Installation Difficulty

Easy (1/5). Two screws and two spade terminals. Disconnect power at the breaker before servicing. Repeated tripping usually points to restricted airflow — replace the filter and confirm blower operation before condemning the switch.
