Ed1 10 Defrost terminated
after maximum time
Check the evaporator status (correct fan operation, expansion valve opening).
Check the position of the defrost probe. It should be placed at the point on the evaporator where the
last part of the ice melts.
Check that the defrost duration is not too short (dP1) is too short
Check fan settings during defrost F3
Ed2 11 Defrost on second evaporator
terminated after maximum time
Check the status of the cabinet: correct operation of the fan, check the opening of the expansion valve.
Check defrost probe position: the probe must be positioned at the point of the evaporator where the last
part of the ice melts.
Check that the dP2 parameter has not been set too short.
Check the fan setting during defrost F3.
