Some of the food is frozen:
• Cabinet too packed with foods - air inlet/outlet blocked.
• Temperature set point adjusted too low.
• Evaporator fan might be defective.

• Ambient temperature too high.

Defrosting is automatically performed (default 4) times every 24 hours, related to the settings
made in the controller under the defrost-parameters. If the product is operating under severe load
(frequent door opening and frequent replenishment), manual defrosting can become necessary.
In order to start a manual defrosting cycle or to stop an ongoing defrost cycle the following must
be done:
Danfoss AKCC550A:
• If the lower button is pushed for more than 4 seconds, during normal operation, an ongoing
defrost cycle will be cancelled or a manual defrost cycle will be started.
During defrost the control LED is lid.
Carel MPXpro:
• Press and hold def for more than 5 sec. during normal operation, in order to perform a
manual defrost, if the evaporator probe temperature is cold enough.
• When the defrost symbol is lit, it does indicate that a defrost is ongoing.
• if def is pressed and held for more than 5 seconds when a defrost cycle is ongoing, the
defrost will be deactivated.
