NO IGNITION ARC ESTABLISHED
1. Reset Control
Motor starts
– Completes 30 second pre-purge cycle.
Gas valve opens, regulating adequate gas pressure.
No flame established
– Primary control locks out after 4 second trial for ignition period.
In order for the functional test described in Step 2 to be
made, the control must reset and the voltage measured
during the 4 second trial for ignition period that occurs at
the end of the 30 second prepurge.
2. Check for 120 volts AC between the neutral line and
the junction of the blue primary control lead and black
ignition transformer lead.
3. Check electrical wiring and connections at ignition
transformer.
4. Check high voltage lead and connection to igniter
electrode.
5. Inspect igniter electrode for cracked ceramic insulator
and correct spark gap (Figure 21).
6. Replace ignition transformer.
Check electrical wiring and
connections.
Check for 120 volts AC between the
neutral line and the other blue wire of
the primary control. Check for 120
volts AC between the neutral line and
the black wire of the primary control.
NOTE: 120 volts AC at these 2 points
should be present when the motor is
turning.
Replace primary ignition
control.
