The Goodman 0130F00036 Limit Switch is a genuine OEM high-temperature safety control (identified by its pink color code) for AMSS920603BNAA gas furnaces and compatible Goodman/Amana equipment. This automatic-reset thermal switch monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow, a failed blower, or a clogged filter.
Limit switches are color-coded to a specific trip temperature. The OEM 0130F00036 guarantees the exact rating and mounting your furnace was engineered for. Installing a wrong-rated generic switch can cause nuisance shutdowns or, worse, defeat overheat protection. For a safety-critical part, only OEM should be used.
Easy–Moderate (2/5) — remove two mounting screws and the spade connectors, then install the new switch in the same orientation. Basic tools required. Disconnect power and shut off the gas before servicing. When in doubt, use a licensed HVAC professional.
