this is a siemens american fridg efreezer but is made by daewoo,original fault was frzr evap iced up so i checked the usual and all was fine so i changed the def sensor,fault reoccured 2 weeks later so i checked all again and heater and o/load ok.could it be a pcb fault not powering the heaters as ive never had this before? and would a daewoo pcb do the job as the 645823 is out of stock at connect.
cheers chris
