SOLUTION
4) Everything appears to be running
correctly but no ice made in the
evaporator.
A)
Freezing system faulty.
(dirty condenser, Presostato o válvula
entrada agua de condensación averiadas o
mal reguladas o falta de refrigerante).
A) Check system.
B) Hot gas valve faulty (outlet pipe
temperature would indicate this).
B) Repalce hot gas valve.
5) The ice cubes form correctly but do not A) The hot gas valve does not open.
A) Check valve.
unstick.
B) The lower cam micro-switch is faulty or
wrongly connected.
B) Reemplazar micro o conectarlo
correctamente.
(Only on water condensed machines)
Presostat faulty or opens too much
C) Regulate water presostat to 40ºC-
43ºC.
D) Faulty presostat.
D) Check or adjust presostat.
6) Low ice production.
A) Water level in pan too low or too high.
A) Check water level. Look at the
position of the buoy.
B) Blocked condenser.
B) Clean condenser.
B)
In
water-cooled
machines: dirty
condenser, badly adjusted valve, pressostat,
faulty
water
inlet
valve
or
faulty
pressostatic valve.
B) Clean condenser; check, adjust or
replace.
C) Faulty hot gas valve, doesn’t close
totaly.
C) Replace.
D) Faulty fan or pressostat, faulty inlet
cooling water valve.
D)
Check
fan
and
re-adjust
pressostat or replace.
E) Refrigerant charge too high or too low.
E) Adjust.
F) Faulty water inlet valve: leaks and does
not close fully.
F) Check and replace.
G) Inefficient compressor.
G) Replace.
7) A sheet of ice forms in pan .

correctly.
B) Wrong pressure on this micro-switch
spring.
B) Check spring pressure and
replace it if it is necessary.
C) In MQ 200 model termostat faulty.
C) Replace termostat.
9) Cubes are formed normally for some
cycles. Then the evaporator stops getting
cold at some point.
A) Moisture in system.
A) Draw vacuum in installation by
heating compressor and dehydrator.
Load with the correct refrigerant.
B) Foreing body blocking capillari at
certain times.
B)
Remove dehydrator.
Unblock capillary and replace with
new dehydrator.
Draw vacuum and reload.
10) The pan remains in stop position
althought cubes have dropped out.
A) Connecting rod micro-swith faulty or in
wrong position.
A) Replace or change position of
micro-switch.
