CHAPTER 10
TROUBLE SHOOTING
10.1 - TEMPERATURE IS TOO LOW
Chap.
Cause
Diagnosis and Remedy
13.1.1
Thermostat
Turn the thermostat knob on a lower number.
13.1.2
Thermostat
The unit runs continuosly without cycling : in
spite of the thermostat position.
If the evaporator is completely frozen replace
the thermostat.
13.1.3
Holding plate is too big
Reduce the cooling surface of the holding plate
(Energy Saving system)
by using the Mod. A090900 ice cube kit
assembly. If the temperature is too low partially
cover the remaining surface with
insulating material.
10.2 - TEMPERATURE IN THE COOL BOX IS NOT LOW ENOUGH
Chap.
Cause
Diagnosis and Remedy
13.2.1
Thermostat
Turn the thermostat knob on a higher number.
OR
Frost on the evaporator
See Chap. 8.7.
13.2.2
Lack of refrigerant
Evaporator in only partially frozen and the unit
runs continuosly (See Point 13.5.1).
13.2.3
Cooling unit no big enough
The evaporator is completely frozen
conveniently localted in the upper side of
the cabinet. The cooling unit is cycling also
when thermostat is in the position 7 but
temperature inside the cabinets is too high.
It means that the cabinet is too big for the
evaporator or the cabinet insulation is too
poor. Should not be convenient for your
to encrease the cabinet insulation and or
replace the evaporator with a bigger one,
you can find a remedy by mooving the
evaporator downwards. Doing so you reduce
the refrigerated area : the cabinet size over
the evaporator will not be cooled.
