Lower reed-switch (58):
• To check the perfect functioning of the lower reed-switch (58), proceed similarly as the upper reed-
switch (54) test, but checking the continuity of the terminal (E) of the circuit board (62) with the aid of
an ohmmeter.
End of cycle microswitch (59):
• To check the end of cycle microswitch (59), use the ohmmeter on terminal (F) of the circuit board (62)
and manually engage the rod at the end of cycle microswitch (59), confirming its perfect functioning.
Movable water sensor (55):
• The movable water level sensor (55) is checked via terminal (C) of the circuit board (62),
performing a direct link between the terminals on the fixed (67) and mobile (55) sensors. In this
condition, there should be continuity in the ohmmeter's reading.
3.4.1 B - COMPONENTS CONTROLLED
BY THE CIRCUITBOARD
• Tighten the screw on the gear lever arm (42) and make use of a voltmeter to check the components
below.
By-pass gas solenoid valve (28):
• With the pointer of the voltmeter on the terminal (H) of the circuit board (62), restart the equipment.
In up to 8 seconds, it should indicate 220V. If it does not, replace the circuit board (62).
Gear motor (60):
• As the running time of the gear motor (60) is controlled by the circuit board (62), and this period is
relatively short, proceed as follows: Position the pointers of the voltmeter on the terminal (J) of the
circuit board (62) and restart the equipment. After approximately 45 seconds, the gear motor (60) will
be switched on. Check if there is voltage (220V) in the terminals (J) of the circuit board (62) If there is
not, replace the circuit board (62).
Water solenoid valve (63):
• After the cleaning cycle, the trough (35) returns to the highest position and, at this time, the circuit
board (62) will switch on the water solenoid valve. With the pointers of the voltmeter, check for voltage
(220V) of the terminal (C) on the circuit board (62). If there is not, replace the circuit board (62).
Micro gear motor (57):
• During the ice formation cycle, check for voltage (220V) on the terminal (L) of the circuit board (62). If
there is not, replace the circuit board (62).
