It clips onto the evaporator coil behind the freezer panel and cuts power to the defrost heater once the ice has melted. We don't have a compatible model list on file, so compare the number on your old part, or check the model and serial number on the label inside your fridge, before ordering.\u003c\/p\u003e\n\u003ch2\u003eSigns of a faulty defrost bimetal\u003c\/h2\u003e\n\u003cp\u003eDuring a defrost cycle a heater warms the evaporator to clear frost, and the bimetal switches it off at a set temperature. If the bimetal fails open, the heater never runs and ice builds up on the evaporator until air can't pass through. The freezer may still feel cold while the fridge section warms up, and frost can show on the back panel. If it sticks closed, the heater may run too long, leaving drips or melted ice. A continuity test at freezing temperature confirms the fault.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Whirlpool part W10225581\u003c\/li\u003e\n\u003cli\u003eDefrost bimetal thermostat\u003c\/li\u003e\n\u003cli\u003eControls the defrost heater in frost-free fridges\u003c\/li\u003e\n\u003cli\u003eNo models on file\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eReplacing the defrost bimetal\u003c\/h2\u003e\n\u003cp\u003eUnplug the fridge or switch it off at the wall, and move the food into an esky. Remove the freezer back panel to reach the evaporator, taking care not to puncture the coil with tools, and let any heavy ice melt first. The bimetal is usually clipped to the coil tubing and joined with a plug or splices. Fit the new one firmly to the same tube so it senses the right temperature.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eMy freezer is fine but the fridge is warm. Could it be this part?\u003c\/h3\u003e\u003cp\u003eIt's a common cause. If the evaporator ices over, cold air can't reach the fridge section. Look for heavy frost behind the freezer panel. The defrost heater and the defrost control can cause the same symptom, so test all three.\u003c\/p\u003e","brand":"Whirlpool","offers":[{"title":"Default Title","offer_id":44551160594510,"sku":"W10225581","price":61.78,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/partsshop.com.au\/products\/w10225581-genuine-whirlpool-fridge-defrost-bimetal-thermostat","provider":"My Store","version":"1.0","type":"link"}
