It has a left hand thread, so it tightens anticlockwise and undoes clockwise. That reverse thread is deliberate, because the spinning fan would gradually work a normal nut loose. It's an easy part to lose or round off during a fan or element change, and the fan blade should never be run without it.\u003c\/p\u003e\n\u003ch2\u003eWhy the Smeg oven fan nut matters\u003c\/h2\u003e\n\u003cp\u003eInside a fan forced oven, the fan blade sits on the end of the motor shaft at the back of the cavity, held on by this nut. If the nut is loose, missing or has a damaged thread, the blade can wobble, scrape against the back panel or element, rattle at speed, or come off the shaft altogether. You may hear clicking or knocking as the oven heats, or notice uneven cooking as airflow drops. Ordinary nuts sometimes get swapped in after a repair, but a standard right hand thread will slowly unwind as the fan turns, so fit the correct left hand part.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Smeg part 902610342\u003c\/li\u003e\n\u003cli\u003eFan motor nut with left hand thread\u003c\/li\u003e\n\u003cli\u003eLocks the fan blade onto the oven fan motor shaft\u003c\/li\u003e\n\u003cli\u003eFor Smeg fan forced ovens\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth\u003eThread\u003c\/th\u003e\n\u003ctd\u003eLeft hand\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eFitting the fan nut\u003c\/h2\u003e\n\u003cp\u003eIsolate the oven and wait until the cavity is cold. Remove the rear cavity cover to reach the fan. Hold the blade still and turn the old nut clockwise to undo it, remembering the left hand thread. Fit the new nut by turning it anticlockwise until snug, without overtightening. Spin the blade by hand to check it runs true and clear of the cover before refitting.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eWhich way do I turn the nut to undo it?\u003c\/h3\u003e\u003cp\u003eClockwise.
