It works alongside the primary limit as a backup over-temperature cutout, typically guarding the blower compartment or a secondary heat zone. If airflow is restricted or temperatures climb past the safe threshold, this switch opens the circuit and shuts the furnace down before damage occurs.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00038\u003c\/li\u003e\n\u003cli\u003eColor Code: Light Blue (auxiliary\/secondary limit)\u003c\/li\u003e\n\u003cli\u003eType: Thermal limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Secondary over-temperature cutout \/ backup protection\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman\/Amana WFD18070S3AXCC and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLike the primary, the auxiliary limit is calibrated to a specific trip temperature, and the blue color code identifies that rating. Installing a generic switch risks either nuisance shutdowns or an ineffective safety net. This OEM 0130F00038 matches the WFD18070S3AXCC's factory spec exactly, so your furnace's redundant protection works as engineered.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eAbout 15–25 minutes. Disconnect power, label and remove the two spade connectors, unscrew the old switch, and mount the new one in the same location and orientation. As with any safety control, confirm solid mounting contact. When in doubt, consult a licensed HVAC technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058216026483,"sku":"GOODMAN-13852","price":5.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-blue-for-wfd18070s3axcc-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
