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.
•
Check module according to testing
procedures information.
•
Clean electrode or burner cap.
•
Replace electrode.
No spark or only random
spark at one ignitor.
Check for cracked ignitor/pinched wire..
Poor continuity to burner cap.................
Bad ground connection or lack of
continuity to ground or ignitor ................
Cracked or broken ignitor extension
lead ........................................................
•
Replace ignitor lead or electrode.
•
Clean burner cap and lead.
•
Tighten ground connection and correct
any breaks in ground path from ignitor
path to unit ground path.
•
Replace ignitor lead.
Unit continues to spark after
knob is turned to OFF
position.
Shorted valve switch/harness ................
Switch has slipped off the valve.............
•
Replace switch/harness. If shorting is
caused by excessive spillovers,
customer education is advised.
•
Carefully reposition switch on valve and
rotate from OFF to high, several times
to verify switch is not broken.
No oven operation in bake or
broil.
No voltage to control. .............................
No voltage from control..........................
Loose wire connection or broken wire ...
•
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. .........................................
Gas pressure too high............................
Failed gas valve .....................................
Loose wire connection or broken wire ...
•
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.
