TO AVOID THE RISK OF ELECTRICAL SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER BEFORE SERVICING, UNLESS TESTING REQUIRES IT.

SPARK MODULE TESTING

When properly operating, the spark module will produce a spark at the ignitor accompanied by a sharp snapping sound each time the ignitor sparks.

The spark module is located under the burner box on the left side.

The sealed top burner units have two (2) spark modules, one (1) on the left and one (1) on the right or one (1) spark module with four (4) ignitor connections.

TO CHECK THE MODULE

1.Disconnect electricity at disconnecting plug, and turn off gas supply to the range.

2.Check wiring against wiring diagram to be sure all terminals and wire-connections are correct and tight.

3.SET VOLT/OHMMETER ON THE 120 VAC SCALE or higher.

4.Attach one (1) meter lead to the "L" wire terminal on the spark module.

7.Turn all top burner knobs to the "LIGHT" positions.

8.No line voltage (115 VAC ± 10 VAC) at test meter indicates the electrical circuit is interrupted before spark module.

9.Line voltage at test meter - check ignitors.

10.If ignitors are OK; then replace ignition module.

TOP BURNER SPARK IGNITORS

A spark ignitor is located between each pair of left and right burners. Sealed burner units have an electrode for each burner. When any of the burner valves is turned to the "LITE" position, the spark switch on the valve closes, supplying 120 VAC to the spark module. This activates the module which produces the spark at the ignitor electrode to light the burner.

TO CHECK THE SPARK IGNITORS

1.Disconnect electricity at main disconnect plug.

2.Disconnect the high voltage spark ignitor leads from the terminals on the spark module.

3.SET THE VOLT/OHMMETER ON THE "RX1" OHM SCALE (adjust zero).

4.Attach one meter lead to a good ground (bare metal) on the range body.

5.Touch the remaining meter lead to the terminal of the ignitor lead. A continuity reading from the ignitor lead indicates the ignitor lead is shorted to ground. If no continuity reading from the ignitor lead to ground, proceed to Step 6.

6.Attach one (1) meter lead to the terminal of the ignitor lead and touch the remaining meter lead on the opposite end of the ignitor lead which is attached to the top burner mounting bracket. Repeat same procedure with the other ignitor lead. No continuity on the lead indicates an open circuit in the ignitor lead wire. (On sealed burner units, one (1) meter lead must be attached to the electrode socket at the venturi.)
