After the heater cycle there's a short drip period, letting meltwater run away before cooling starts again. A timer that sticks in the cooling position lets ice pack the coil until air can't flow, so the freezer frosts up and the fresh food section turns warm. One that sticks in defrost leaves the whole fridge silent and warming. Many timers have a slot you can turn by hand to force a cycle, which helps prove which way it has failed.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Electrolux group part 4055612008\u003c\/li\u003e\n\u003cli\u003eCross reference 1448728K\u003c\/li\u003e\n\u003cli\u003e8 hour defrost cycle, 7 minute drip time\u003c\/li\u003e\n\u003cli\u003eInvensys defrost timer\u003c\/li\u003e\n\u003cli\u003eSuits Westinghouse, Kelvinator, Simpson and Electrolux frost free fridges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDefrost interval\u003c\/th\u003e\n\u003ctd\u003e8 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDrip time\u003c\/th\u003e\n\u003ctd\u003e7 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eReplacing the defrost timer\u003c\/h2\u003e\n\u003cp\u003eUnplug the fridge at the wall first. Take a clear photo of the timer terminals and wire colours before pulling any connector, as the wiring order matters. Transfer the wires to the same terminals on the new timer, refit it in its bracket and power up. Allow a full day of running before deciding whether the defrost problem is solved.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eMy fridge is frosted up, is it always the timer?\u003c\/h3\u003e\u003cp\u003eNot always. A heavy ice build-up can also come from a failed defrost heater or defrost thermostat. Advance the timer by hand into defrost and check whether the heater warms up. If it does, the heater circuit is working and the timer becomes the prime suspect.\u003c\/p\u003e","brand":"Electrolux","offers":[{"title":"Default Title","offer_id":44547833167950,"sku":"4055612008","price":106.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3489\/7998\/files\/4055612008-genuine-westinghouse-fridge-defrost-timer-8-hour.jpg?v=1792025594","url":"https:\/\/partsshop.com.au\/products\/4055612008-genuine-westinghouse-fridge-defrost-timer-8-hour","provider":"My Store","version":"1.0","type":"link"}
