The Goodman 0130F00038 is a genuine OEM auxiliary limit switch, identified by its light-blue body color to distinguish its trip temperature from other limits in the cabinet. Designed for the AMSS960402BNAA gas furnace, this secondary safety guards a specific zone — commonly the blower compartment or a supplemental heat-exchanger location — and opens the control circuit if that area exceeds its rated temperature. The color coding matters: each auxiliary limit in a Goodman furnace is calibrated to a different set-point, so installing the correctly colored switch is essential for proper protection.
Only the OEM 0130F00038 guarantees the exact light-blue-rated cut-out point your furnace requires. A generic or wrong-color substitute may trip at the wrong temperature, causing nuisance shutdowns or bypassing intended protection. For a coded safety switch, always match the OEM color and part number.
Easy (1/5). Disconnect power, note the terminal orientation, unplug the spade connectors, remove the mounting screws, and fit the new switch in the same spot. Verify the replacement is light blue before installing. Typical time: 10–15 minutes.
