The compressor is running but the
temperature in the chamber does not
drop
Evaporator packed with ice.
Start a defrost cycle lasting at least
30 minutes and remove the condensate drain
plug from the bottom of the chamber.
WARNING: Always perform at least one
defrost at the end of the working day.
If necessary, depending on the type of
process, perform a quick defrost between one
cycle and the next.
All evaporator fans are faulty.
See in this table *All evaporator fans - in the
chamber - failed.
Incorrect chamber probe reading.
Contact an authorized dealer or service centre.
The compressor works but the
temperature in the chamber drops
slowly
Evaporator packed with ice.
Start a defrost cycle lasting at least
30 minutes and remove the condensate drain
plug from the bottom of the chamber.
WARNING: Always perform at least one
defrost at the end of the working day.
If necessary, depending on the type of
process, perform a quick defrosting between
one cycle and the next.
Dirty condenser filter.
Clean the filter as shown in the User manual.
System empty of gas.
Contact an authorized dealer or service centre.
One or more evaporator fans are
not working (depending on the
model).
Contact an authorized dealer or service centre.
Presence of frost on the product and
on the cell during a freezing function.
Door seal does not guarantee
tightness to the body.
Check the tightness of the door seal on the
frame covers. Insert a sheet of paper between
the seal and the frame covers and, once the
door is closed, check all around the perimeter
of the chamber that the sheet of paper is not
free to move. Where the sheet moves easily,
there will be puffs of frost towards the inside
of the chamber (happening when the drain
plug on the bottom is not used). If, on the
other hand, the frost is present evenly over
the entire chamber, it means that the seal
is not tight (the sheet of paper moves freely
around almost the entire perimeter) and it is
necessary to either align the door, or replace
the door seal with a new one (recommended
once a year). Contact an authorized dealer or
service centre.
The uniform presence of frost on the product
and chamber is also a symptom of excessive
door opening during negative cooling cycles.
