had two of these call outs in the last year for different fridges.
The evaporator in the freezer is freezing over at the top enough to stop the fan. i have defrosted units and cleared all the ducting and cover to allow airflow. both fridges seem to be OK as i haven’t had any call backs on them but an not sure for the reason for the extreme icing at the top of the evaporator.the heaters test ok and the are no other issues i can identify. Can anyone advise or has anyone come across this?
thanks
