This thermal safety switch monitors temperature in its section of the furnace and opens the control circuit if it detects an overheat condition — protecting the heat exchanger and cabinet from damage caused by restricted airflow, a failed blower, or a dirty filter. A limit switch that has tripped permanently or lost calibration will prevent the furnace from firing, so an exact-match replacement is essential for safe operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Auxiliary thermal high-limit switch\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (trip\/reset temperature identifier)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens control circuit on overheat, protects heat exchanger\u003c\/li\u003e\n\u003cli\u003eCompatible model: WFD195045S3BAB (and select Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003eTerminals: OEM spade connections and mounting flange\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe color-coded \u003cstrong\u003eOEM 0130F00038\u003c\/strong\u003e is calibrated to the precise trip and auto-reset temperatures Goodman specifies for this furnace. Because this is a safety device, the light-blue temperature rating must match exactly — an incorrect generic switch can nuisance-trip or, worse, fail to protect the equipment. Always match the OEM part number and color.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5)\u003c\/strong\u003e — Two mounting screws and two spade terminals, typically under 15 minutes.

If the switch keeps tripping after replacement, investigate airflow (filter, blower, ducting) rather than bypassing the safety.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058218811763,"sku":"GOODMAN-13929","price":5.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-light-blue-for-wfd195045s3bab-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
