Mounted on the heat exchanger or burner area, it opens the control circuit if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard. A failed or nuisance-tripping primary limit is a leading cause of a furnace that fires briefly and then shuts down, or won't run at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0130F00035\u003c\/li\u003e\n\u003cli\u003eColor Code: Purple (primary\/high limit)\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset thermal limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens heat circuit on over-temperature; auto-resets on cooldown\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\u003eLimit switches are trip-temperature specific, and the color code exists precisely so the correct cutout point is installed. A generic switch with the wrong trip temp will either nuisance-trip and short cycle, or fail to protect the heat exchanger at all. This OEM 0130F00035 is factory-calibrated to the WFD18070S3AXCC's exact limit spec — the safe, correct choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eRoughly 20–30 minutes. Cut power at the disconnect, note the two wire positions, remove the mounting screws, and transfer the wires to the new switch. Because it is a life-safety device, verify orientation and firm heat-exchanger contact. If you're unsure, have an HVAC technician confirm the installation.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058215993715,"sku":"GOODMAN-13851","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-switch-purple-for-wfd18070s3axcc-0130f00035","provider":"National HVAC Parts","version":"1.0","type":"link"}
