The unit will behave differently depending on which switch is not functioning or is not
adjusted correctly. The end result is always a #4 Diagnostic Light flashing. Switch #1 is
wired to the
Normally Open
Connectors. The voltage on this switch is
120 Volts AC
.
The switch is connected to the
Gearmotor
. Its function is to
complete the Rotation
that
was started by the Control Board.
Switch #2 is wired to the
Normally Closed
Connectors. The voltage is
5 Volts DC.
This
switch is connected to the
Control Board through the High Limit circuit.
Its function
is
to signal to the Control Board that the Drum rotated.
Please note how the switches drop in
the notches in the switch disc.
The position shown in figure 12 is
the
Normal Operating
position of
both switches.
In these positions:
Switch 1 is
Normally Open
Switch 2 is
Normally Closed
Figure 12
What happens when the Switches are not adjusted properly?
When the unit is in
Idle Mode,
the Control Board monitors the two Orange wires that are
connected to the #2 Switch. This circuit must be closed. The switches should be in the
position shown in Figure 12. If the switches are in a similar position as shown in Figure
13,
while in
Idle Mode
, the #5 LED light on Control Board will be
ON
(not flashing).
This indicates the #2 Switch is Open instead of Closed.
If the #5 light is on will indicate the
Control Board is in the
Synchronization
Routine
.
In this Routine the Control Board will
send power to the gearmotor to rotate the
drum until the #2 Switch closes.
If the Drum is jammed, the switches
will be on the edge of the disc as
shown in Figure 13.
If the pot is jammed, correct the problem
before starting the unit
