When supply air temperature exceeds the set point, the switch opens the control circuit and shuts down the burner, preventing heat exchanger damage and potential safety hazards. Manufactured by Thermodisc Inc, this switch is an OEM accessory replacement used in residential and light commercial gas furnace applications. Licensed HVAC technicians install this part during routine limit-switch replacement or as part of a no-heat diagnostic repair.\u003c\/p\u003e\n\u003cp\u003eThis primary limit switch is suited for gas furnace systems where the existing limit switch has failed open, failed closed, or is triggering nuisance trips due to age or drift. It fits into the furnace cabinet in the air-stream path near the heat exchanger, where it monitors supply air temperature continuously during burner operation. It ships in pack multiples of 2, making it practical for stocking in a service van or supply room for common furnace service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOperating range of 30 to 300 degrees F for primary overtemperature protection\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 2 inches depth, 1.51 inches height, and approximately 1.97 inches width\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.0639 pounds for easy handling in tight furnace cabinet spaces\u003c\/li\u003e\n  \u003cli\u003eOEM accessory classification for direct replacement service use\u003c\/li\u003e\n  \u003cli\u003eManufactured by Thermodisc Inc, a recognized supplier of thermal cutoff and limit devices\u003c\/li\u003e\n  \u003cli\u003eAvailable in pack multiples of 2 for van-stock efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement primary limit switch for residential and light commercial gas furnace systems requiring a 300 degrees F rated limit device.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis part is installed by licensed HVAC technicians. Always shut off power to the furnace at the disconnect switch and turn off the gas supply before replacing a limit switch. Verify the root cause of limit tripping before replacing the switch, as a failed limit switch may be a symptom of restricted airflow, dirty filters, or blocked flues. Follow applicable local mechanical codes and the furnace manufacturer service documentation during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 30 to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Height\u003c\/strong\u003e: 1.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Width\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0639 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Mexico\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Multiple Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Goodman\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: b1370195\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GOODMAN","offers":[{"title":"Default Title","offer_id":51138765160754,"sku":"B1370195","price":24.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305526159.jpg?v=1778263185","url":"https:\/\/voomisupply.com\/products\/goodman-b1370195-primary-limit-switch-300-degrees-f","provider":"Voomi Supply","version":"1.0","type":"link"}
