Came in to find the ice dispenser door cycling about every ten seconds and the control lights/displays flashing rapidly. accessed the control panel and removed the six wire lead to the ice dispenser- that stopped the door cycling.. then removed the three-wire lead (red/bk, bl/bk and bl/w) which seems to have restored the display. it sounds as if something is making a high pitched whine in back, but no circulation fan movement. Any ideas?
