6-4
No ignition when a particular Burner is turned on. Sparking is either evident at the Burner's spark gap or the associated clicking can
be heard
POTENTIAL CAUSES
ACTION
5.1.1 Check gas flows to appliance
5.1.2
Check operation of the Gas Solenoid in series with gas manifold. Ensure correct gas flow when energized
with 120Vac 60Hz.
5.1.5
Check pins on Connector Headers and Receptacles are not contaminated and mate correctly, particularly 10
Way Input Connector, terminal 9 LINE, terminal 10 GAS SOLENOID LINE. Excessive wear may deteriorate a
positive connection.
5.1.6
Check for gas blockage in lines to the individual burner not igniting
5.2.2
Check connection between the HV Lead and the Electrode connection at the Burner.
5.2.3 Check connection at both ends of the HV Lead for damage or breakdown of the insulation.
5.2.4
Check HV Cable for breakdown through the cable insulation to the metal within the appliance.
5.2.5
Check actual electrode for insulator damage.
5.2.6 Check dimensions of the Spark Gap, electrode tip to Burner (about 2 dimes) is within the maximum specifications.
5.2.7 Check HV Cable for excessive contact with the chassis or earthed metal parts within the appliance.
5.1.7
Check for correct operation of gas valve
5.1.8
Check for wet or dirty burners ports that could result in blockage of the ports
5.1.4
Check integrity of wiring from the Gas solenoid to the 10 Way Input connector of igniter Module. Especially
check there is 120Vac between P2-10 ; and P2-9.
No gas flow or poor gas
flow in the vicinity of the
Spark Gap
Even though sparking
can be heard, no
sparking is evident at the
Spark Gap between
electrode tip and Burner.
5.1.3
Check Wiring and Connections to the Gas solenoid White and Black wires from main harness to the Gas solenoid
5.1.9
Check that the burner is correctly assembled
5.2.1
Check connection between the HV Lead and the Spark/Sense Electrode connection , (S1…S5 on the ignition
module.)
Burner is turned on and ignition occurs. However sparking continues after ignition
POTENTIAL CAUSES
ACTION
Wiring problems on re-
assembly of appliance
6.1.1 Check the electrodes are connected to the Spark / Sense inputs on the ignition
module according to the color map on the label inside the burner box.
6.2.1 Check electrical continuity of the Burner Assembly from Burner ports to the chassis.
6.2.2 Check electrical continuity from the igniter HV Output pins to the electrode tip.
6.2.3 Check electrical continuity from the igniter Input pins N, EARTH to electrical
ground.
6.2.4
Check electrical continuity from electrical ground to the appliance chassis
6.2.5 Check electrical continuity from electrical ground to the Secondary Winding
connection of the transformer within the appliance.
6.3.1
Check gas ports adjacent to the electrode for blockage.
6.3.2 Check gas regulator for problems reducing the pressure. Lower pressure results in
smaller flame which moves away from the detection electrode and reduces detected
flame level below the spark threshold level.
Electrode out of position
following re-assembly of
appliance.
6.4.1 Check position of the electrode (about 2 dimes). Any change of
height and radial position relative to burner will effect flame detection strength. If
outside the operating limits of the Reigniter module, flame cannot be detected and
spark will not occur.
Faulty IGNITER module
6.5.1 Replace module if step 5.1-5.9 are good.
Verify replacement module corrects the fault
No flame or poor flame in
the vicinity of the electrode
tip
Poor Ground in
appliance.
For correct flame detection
the circuitry requires
grounding and electrical
continuity of the Burner
assembly, appliance chassis
neutral & ground (green wire
connection on the igniter
input and the secondary
of the transformer.
