The Goodman 0130F00038 is a genuine OEM auxiliary high-limit switch, color-coded light blue for its trip temperature, used on the AMVM971005CNBA and compatible AMVM97 / GMVM97 furnaces. This normally-closed thermal cutout opens the control circuit if a section of the furnace exceeds its safe operating temperature — protecting the heat exchanger, blower housing, and surrounding cabinet from overheating caused by restricted airflow or a dirty filter.
Limit switches are calibrated to a precise trip temperature — the light-blue color code is not cosmetic. Installing a switch with the wrong rating can either allow dangerous overheating or cause nuisance shutdowns. The OEM 0130F00038 guarantees the correct calibration and terminal fit.
Easy (1/5) — Two mounting screws and two spade terminals. Cut power, swap the switch, reconnect wiring. Roughly 10–15 minutes.
