Dave K for Model Number kcms145jss1 My microwave quit heating. Everything else seems to be working. Would there be something else than the magnatron being bad. I didn't see a listing for a diode that I read about in your forums? THANK YOU !
Answer Hello Dave. You will need to look and see if the magnets on the magnetron are cracked, or if the tip is burnt out. Also test the diode WP8205489 and make sure it is ok. It should only read resistance in one direction. It could also be the H.V. transformer 8172170 causing the unit not to heat. Hope this helps. Read More...
