The 0130F00038 is a genuine OEM auxiliary high-limit switch, identified by its light blue body, for the Goodman/Amana AMVC81155CXAB furnace. This normally-closed thermal safety switch opens the low-voltage control circuit if a section of the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower — shutting down the burners to prevent heat-exchanger damage.
Color coding on Goodman limit switches maps to a specific factory trip temperature. Installing the exact OEM 0130F00038 guarantees the correct cut-out point for this furnace's heat exchanger and cabinet design. A generic switch with the wrong rating can nuisance-trip on normal cycles or, worse, fail to trip when needed. Always match the OEM color and part number.
Easy (1/5). Cut power at the disconnect, remove the burner/control door, unclip the two spade terminals, remove the mounting screws, install the new switch, and reconnect. Takes about 15 minutes with a nut driver. Confirm airflow issues are resolved so the new switch isn't tripped by the same underlying fault.
