b. As a. above.
c. Check the position of the freezer
air sensor;
Check refrigerant system for leaks
and/or blockages.
d. At the end of the defrost cycle the
compressor observes a protection
time delay parameterised in the
memory, this allows the water
produced during the defrost cycle
to drain away completely.

before the overload switches
compressor OFF.

through the system pipes can produce
gurgling, bubbling, roaring or humming
sounds.
