It sits against the evaporator and melts away the frost that builds up between cooling cycles. The description also includes the reference 790, so compare that and the part number with the label or tag on your old heater before ordering.\u003c\/p\u003e\n\u003ch2\u003eFrost free fridge icing up? Signs of a failed defrost heater\u003c\/h2\u003e\n\u003cp\u003eIn a frost free fridge, a timer or control board switches the defrost heater on at intervals to clear ice from the evaporator coil. If the heater fails, frost keeps building until it blocks the airflow. The freezer may still feel cold while the fridge section warms up, you might find a thick layer of ice behind the rear panel, and the fan can start scraping on the ice. A heater with no continuity on a multimeter is faulty, but the defrost sensor, thermal fuse or control can fail with the same symptoms.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Fisher \u0026amp; Paykel defrost heater, part 847026\u003c\/li\u003e\n\u003cli\u003eDouble heater type\u003c\/li\u003e\n\u003cli\u003eRated at 230V\u003c\/li\u003e\n\u003cli\u003eDescription reference 790\u003c\/li\u003e\n\u003cli\u003eFor frost free fridges and freezers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e230V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eDouble\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eChanging the defrost heater\u003c\/h2\u003e\n\u003cp\u003eSwitch the fridge off at the wall and unplug it, then move food somewhere cold. Remove the internal panel to expose the evaporator and let any ice melt naturally rather than chipping at it, as a punctured coil means a sealed system repair. Photograph how the heater is clipped and wired, fit the new one the same way, and check the drain is clear before refitting the panel.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eHow do I test my old defrost heater?\u003c\/h3\u003e\u003cp\u003eWith the fridge unplugged, disconnect the heater and measure across its terminals with a multimeter. An open circuit means the heater has failed. If you get a reading, the heater is probably fine, so check the defrost sensor, thermal fuse or control next.\u003c\/p\u003e","brand":"Fisher \u0026 Paykel","offers":[{"title":"Default Title","offer_id":44550741917774,"sku":"847026","price":78.98,"currency_code":"AUD","in_stock":true}],"url":"https:\/\/partsshop.com.au\/products\/847026-genuine-fisher-and-paykel-double-defrost-heater-230v","provider":"My Store","version":"1.0","type":"link"}
