This normally-closed thermal safety switch opens the control circuit if it senses an over-temperature condition — typically caused by restricted airflow, a dirty filter, or blower failure — protecting the heat exchanger and cabinet from overheating. When an auxiliary limit fails open or drifts out of spec, the furnace may lock out on high limit or refuse to fire.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eType: Auxiliary high-limit safety switch, normally closed (auto-reset)\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue temperature rating\u003c\/li\u003e\n\u003cli\u003eFits: Goodman WFM18090S5CXCC and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eTerminals: Standard 1\/4\" quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated safety devices — the trip and reset temperatures are matched to the specific furnace cabinet. OEM guarantees the correct light-blue temperature rating; substituting a switch with a different trip point can allow unsafe operation or cause nuisance trips. Always use the exact OEM part for safety controls.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy (DIY-friendly)\u003c\/h3\u003e\u003cp\u003eTwo mounting screws and two push-on wire terminals.
