This automatic-reset thermal switch monitors temperature in the blower or secondary heat area and interrupts the circuit if it detects an overheat condition — protecting the heat exchanger, wiring, and cabinet from heat damage. A failed or drifting limit switch can cause the furnace to lock out, run the blower continuously, 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 limit switch, automatic reset\u003c\/li\u003e\n\u003cli\u003eColor code: Light blue (temperature-rated identifier)\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCH950905DXAC and compatible gas furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Secondary high-temperature overheat protection\u003c\/li\u003e\n\u003cli\u003eMounting: Bracket \/ snap-disc style, model-specific location\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe light-blue color coding designates a specific trip temperature calibrated for this furnace platform. Installing a generic switch with the wrong set point can cause premature nuisance trips or, worse, fail to open when it should. This OEM part guarantees the correct trip temperature and terminal configuration, so the furnace's safety logic behaves exactly as designed.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy\u003c\/strong\u003e — usually under 20 minutes. Disconnect power, remove the access panel, note or photograph the wire terminals, unscrew the old switch, and mount the new one in the same position and orientation. Reconnect the leads, replace the panel, restore power, and verify a normal heat cycle. Always de-energize the furnace before servicing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058067128691,"sku":"GOODMAN-10046","price":12.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auxiliary-limit-switch-for-gch950905dxac-furnace-0130f00038","provider":"National HVAC Parts","version":"1.0","type":"link"}
