The Goodman 0130F00036 is a genuine OEM high-limit switch — identifiable by its pink temperature-code marking — for the WFM18115S5CXCC and compatible Goodman and Amana gas furnaces. This switch protects the furnace by opening the control circuit if supply-air temperature climbs beyond its rated trip point, guarding the heat exchanger against overheating from restricted airflow, a dirty filter, or blower failure. The color code identifies the specific factory-calibrated trip temperature, so matching it exactly is important.
This genuine OEM limit switch is factory-calibrated to the pink-coded trip temperature specified for your furnace. Generic substitutes with the wrong trip point cause either nuisance shutdowns or inadequate overheat protection. Because this is a safety-critical component, always match the OEM color/temperature code.
Easy (2/5). Mounts with one or two screws and two spade terminals. Shut off power and gas before servicing. If the limit trips repeatedly, address the airflow restriction — a dirty filter, closed registers, or a failing blower — rather than simply replacing the switch.
