ON/OTF SWITCHES
The
On/Off switch is designed
to
handle
currents
as
higfr as 20 Amps.
The
cunent values
running
through the
switch are very
small at 12 VAC.
Therefore when
checking
the
switch for
continuity, it
is
important
to set the
ohm meter
on the
R x 100
scale,to
read
possible
resistances
up
to
1.0
ohm.
Any
resistance
reading of 1.0
ohms or
greater
will
drop the 12
VAC
and- cause
the control not
to operate.
When
replacing the rocker
switch,
be sure that
the switctr
has a
protective
boot
surrounding its
body as
shown
in
figure 6. This
boot keeps
out
grease
and moisture,
preventing
short circuits.

EMITTING
DIODE
(LED)
The LED
below each temperature
control
knob
illuminates
when
that zone
of the
griddle
is
calling for
heat.
If the
gdddle
is heating
and maintaining
temperature
yet
the
LED is
not
illuminating, check for
1.5 to 2.0 VDC
to
the
LED.
If
the
voltage
is
present,
check
to
be sure the LED
is
wired
properly.
The
light emitting
diode is
polarity
sensitive and
the wires should
not be reversed. Wiring
of the LED
incorrectly
rnay damage it.
See ftgare
7.
The
red LED
wire
goes
to the red
terminal and
the
black to
the black terminal.
If the LED
still does
not illuminate,
then it can
be
determined
inoperative.
