Found out bottom door for freezer was open a little, causing the defrost thermostat to break (looking at it ,expanded from the metal housing] i took out racks, turned unit off and took the screws out of the back cover plate. after defrosting the ice, the rest was easy, i unclipped the thermostat from the pipe of the evaporater and instated the new one , put everything back together and it was fixed! found out this was a $300 repair and the longest time was defrosting the ice
