Troubleshooting Chart
Problem Possible Cause Correction
Burners will not ignite; no
spark at top burner.
Poor ground on burner cap ...................
.
Weak or failed spark module ................
.
Low gas pressure..................................
.
Clogged burner port ..............................
.
Clean burner cap.
Replace spark module.
Verify pressure 4" WCP for natural, 10"
WCP for LP.
Clean burner cap.
Burner will not ignite. No
spark to burner ignitors
when burner knob is rotated
to "LITE" position.
No 120 VAC to range............................
.
Micro switch contacts not closing .........
.
Faulty wiring. Bad connection at
burner electrode and electrode socket .
.
Inoperative spark module .....................
.
Electrode dirty. Burner cap dirty ...........
.
Cracked or broken electrode,
electrode wire or electrode socket ........
.
Verify voltage at wall outlet.
Check wiring against appropriate wiring
diagram. Verify all terminals and
connections are correct and tight.
Check micro switch contacts.
Check wiring against appropriate wiring
diagram. Verify all terminals and
connections are correct and tight.

.
Bad ground connection or lack of
continuity to ground or ignitor ...............
.
Cracked or broken ignitor extension
lead .......................................................
.
Replace ignitor lead or electrode.

.
Check for 120 VAC at control. If no
voltage check power source.
Check 120 VAC to ignitor, if no voltage,
replace control.
Verify all connections are clean and
tight, replace broken wire.
No gas flows to burner.
Ignitor glows red.
Failed ignitor. ........................................
.

.
Check ignitor current draw, 3.2 – 3.6
Amps. Replace ignitor if it fails test.
Check for correct gas pressure. Natural
gas pressure should be 5" WCP and LP
gas pressure should be 10" WCP.
Check gas valve for continuity.
Verify all connections are clean and
tight, replace broken wire.
