OP
The door is open (or the door switch is closed in another manner).
A1
Door alarm "dA" was activated.
A2
Local alarm, maximum value was activated (LHL)
Room temperature sensor is defective. The sensor must be replaced by the service department. The
F1
cabinet will still approximately maintain the preset temperature with the use of an emergency program.
If "F2" is shown, the evaporator sensor is defective, or there is extreme icing up of the evaporator.
Initially, the unit must be completely defrosted one single time (disconnected, after which the cabinet
must stand with an open door for 24 hours), Important - condensation container under the unit may run
F2
over in connection with this!). If the fault subsequently continues to be displayed, then the service
department must replace the sensor a quickly as possible. The pre-set temperature will continue to be
maintained, and the defrosting phase will occur gradually without temperature restrictions.
If "F3" is displayed, there are problems with the condensation sensor. This sensor only protects against
overheating, and it has no influence on the temperature regulation in the cabinet. It ought however to
F3
be replaced as quickly as possible, so the protection against overheating is re-established
Faults in the second condensation sensor in connection with units with two
F4
cooling motors (see fault message "F3").
