Spark Module Test

Surface Burner Igniter Will Not Spark

To avoid risk of electrical shock, personal injury,
or death, disconnect electrical power source to
unit, unless test procedures require power to be
connected. Discharge capacitor through a resistor
before attempting to service. Ensure all ground wires
are connected before certifying unit as repaired and/
or operational.
1. Check for and remove any foreign objects/soil
buildup around the igniter and operate burner again.
2. If still inoperative, disconnect power to the range.
3. Remove the control panel from the range.
4. Disconnect the wire harness from the inoperative
spark module.
5. Reconnect power and test for 120 VAC from the
black to the white wire.
6. If 120 VAC is present, disconnect power and
reconnect wire harness. (If no 120 VAC, check wiring
and high limit.)

7. Remove the grate, burner cap, and burner head.
8. Disconnect the black wire from the back of the spark
module.
9. Check for 0 ohms between the black wire and the
metal top of the igniter. (If open, replace wire.)
10. If 120 VAC is present in step 5 and the black igniter
wire has continuity, replace the spark module.
