When supply air temperatures exceed the rated threshold, the switch opens the control circuit and shuts down the burner, preventing heat exchanger damage and reducing fire risk. Rated at L205-20F, the switch opens at 205 degrees F and resets with a 20-degree F differential. At 0.11 pounds and compact dimensions of 5.55 inches by 3.5 inches by 1.3 inches, it installs directly into the furnace cabinet without modification. This is a genuine OEM replacement part, ensuring proper calibration and fit.\u003c\/p\u003e\u003cp\u003eThis hi limit switch is designed for use in residential gas furnaces. It is confirmed compatible with G96VTN, N92ESN, and N95ESN unit families, among others. The switch mounts in the furnace cabinet along the heat exchanger or plenum, where it monitors air temperature during heating cycles. Licensed HVAC technicians replace this component during no-heat calls, nuisance-trip diagnostics, or as part of a heat exchanger inspection. Consult the full model compatibility list for complete fitment details before ordering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGenuine OEM replacement part for precise calibration and drop-in fit\u003c\/li\u003e\n\u003cli\u003eOpens at 205 degrees F with a 20-degree F reset differential (L205-20F rating)\u003c\/li\u003e\n\u003cli\u003eProtects heat exchanger and system components from damage caused by overheating\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 5.55 inches x 3.5 inches x 1.3 inches for straightforward cabinet installation\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.11 pounds, minimizing stress on mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eConfirmed compatible with INTERNATIONAL COMFORT PRODUCTS G96VTN, N92ESN, and N95ESN furnace units.

Before servicing, shut off power to the furnace at the disconnect switch and set the thermostat to the off position. The switch is typically mounted to the heat exchanger housing or plenum panel using manufacturer-specified fasteners — do not overtighten mounting hardware on the switch body. After installation, verify the control circuit resets properly and monitor the furnace through a full heating cycle to confirm normal limit switch operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: L205-20F (opens at 205 degrees F, 20 degrees F reset differential)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.55 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INTERNATIONAL COMFORT PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1184879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNATIONAL COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51467701092658,"sku":"1184879","price":22.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947582.gif?v=1783910709","url":"https:\/\/voomisupply.com\/products\/international-comfort-products-1184879-hi-limit-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
