Locate the thermistor on the back wall or ceiling of the fresh food compartment — it is typically clipped into a bracket and connected by a 2-wire harness. Unclip the old sensor, disconnect the harness, connect the new thermistor, and clip it into place. Restore power and monitor temperature over the next 2–4 hours to confirm stable readings.\u003c\/p\u003e\n\n\u003ch3\u003e✓ Compatible Models\u003c\/h3\u003e\n\u003cp\u003eConfirmed compatible with a wide range of Frigidaire and Electrolux refrigerators including FRS, FFSS, FFTR, GLRS, and Electrolux EI and EW series models. \u003ca href=\"\/pages\/contact\"\u003eContact us to verify your model number\u003c\/a\u003e before ordering.\u003c\/p\u003e\n\n\u003ch3\u003e💡 Pro Tip\u003c\/h3\u003e\n\u003cdiv class=\"pro-tip\"\u003e\n  \u003cstrong\u003eTest Before You Replace:\u003c\/strong\u003e\u003cbr\u003e\n  You can confirm a failed thermistor with a multimeter before ordering.

A reading of OL (open loop) or near zero confirms the sensor has failed. This takes 2 minutes and eliminates any guesswork before the part arrives.\n\u003c\/div\u003e","brand":"Frigidaire","offers":[{"title":"Default Title","offer_id":52910622736673,"sku":"5303918775","price":27.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/Frigidaire_Fresh_Food_Thermistor_5303918775_Fix_Refrigerator_Temperature_Problems.png?v=1782697187","url":"https:\/\/xpartsupply.com\/products\/frigidaire-fresh-food-thermistor-5303918775-fix-refrigerator-temperature-problems","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
