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.
Spark Module Test
Surface Burner Igniter Will Not Spark
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.)
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.
Spark Module Test (Stack Burner Valve)
Surface Burner Igniter Will Not Spark
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. Reconnect power.
5. With the stack burner switch in the off position, test
for 120 VAC across switch wires. (If no 120 VAC,
check wiring.)
6. With the stack burner switch in the on position,
test for 120 VAC across switch wires. (If 120 VAC
present, replace switch.)
7. Remove the grate, burner cap, and burner head.
8. Disconnect power.
9. Disconnect the black wire from the spark module.
10. Check for 0 ohms between the black wire on spark
module and the metal top of the igniter. (If open,
replace wire.)
11. If 0 ohms present in step 10, replace the spark
module.
