2.
Access the ignition control module in the power
supply box.
3.
Remove the jumper wire between terminals
marked with an asterisk (*) and an 8.
Fig. 45
4.
Set VOM to micro amp scale (DC), and connect
meter leads at the same terminals. Negative (-)
meter lead to the asterisk (*) terminal, and
positive meter lead to terminal 8.
5.
Turn on power switch, and set cooking control to
call for heat.
6.
Meter reading should be above 1.0 micro amp
(minimum) and steady.
A.
If reading is greater than or equal to the
value given, then flame sense current is
within tolerance.
1)
Turn off power switch and replace
jumper wire.
B.
If reading is less than the value given, turn
off power switch and replace jumper wire.
1)
Perform ELECTRONIC IGNITION
CONTROL TEST.
ELECTRONIC IGNITION CONTROL
TEST
If the ignition control module is not generating a spark
to ignite gas pilot, perform the following checks.
1.
Turn on the power switch, and verify the ignition
control module is receiving power from the
transformer.
A.
If 24VAC is present between terminals 5
and 6 on the ignition control module, then
module is receiving power. Turn off the
power switch, and continue with procedure.
B.
If 24VAC is not present, then find the source
of the problem.
2.
Disconnect power to the machine.
Shut off the gas
before servicing the unit and follow
lockout / tagout procedures.
All gas joints disturbed during
servicing must be checked for leaks. Check with a
soap and water solution (bubbles). Do not use an open
flame.
3.
Verify all electrical connections on the ignition
control module are secure.
4.
Verify the ground wire connections on the ignition
control module and the gas pilot mounting
bracket are clean and secure. The gas pilot
should have good metal to metal contact to the
pilot mounting bracket on the fryer.
5.
Remove the gas pilot and check the following:
A.
Inspect the ceramic insulator on the ignitor/
flame sense electrode for cracks or
evidence of exposure to extreme heat,
which can permit leakage to ground. If either
of these conditions exist, install a
replacement gas pilot.
B.
Inspect the ignitor electrode and ground clip
for contaminates or corrosion. Clean those
surfaces as necessary.
C.
The gap between the ignitor/flame sense
electrode and the ground clip should be 1/8
inch. If the gap is outside of this dimension,
bend the ground clip as necessary, to make
the adjustment.
