Goodman uses the pink color code to identify this switch's specific trip temperature. It is a normally-closed thermal safety that opens and cuts the gas valve if the heat-exchanger area exceeds its rated limit — protecting against a failed blower, blocked filter, or restricted ductwork.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 0130F00036\u003c\/li\u003e\n\u003cli\u003eCategory: Limit Switch — primary high limit\u003c\/li\u003e\n\u003cli\u003eColor Code: Pink (denotes factory-set trip temperature)\u003c\/li\u003e\n\u003cli\u003eOperation: Normally closed, opens on overtemperature (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFD18115S5CXCB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eType: OEM factory replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are matched to the furnace by \u003cstrong\u003etrip temperature\u003c\/strong\u003e, and the pink code exists specifically so you install the right one.
