The Goodman 0130F00036 is a genuine OEM high-limit safety switch, color-coded pink to indicate its factory temperature set point, designed for the AMEC961205DNAC gas furnace. This thermally activated switch monitors heat-exchanger temperature and automatically interrupts the burner circuit if the furnace overheats — protecting against cracked heat exchangers and fire hazards caused by restricted airflow, a dirty filter, or a failing blower.
Limit switches are calibrated to a precise trip temperature — the pink color code identifies that exact rating. Installing a generic switch or the wrong color risks either nuisance trips or, worse, failure to trip during a genuine overheat. For a safety-critical component, always match the OEM color and part number exactly.
Easy. The switch is held by two screws with two spade terminals — about 10 minutes. Cut power at the breaker, note the terminal orientation, swap the switch, and confirm firm mounting against the heat-exchanger panel. Confirm the pink color matches your original before installing.
