Burners will not ignite; no	Weak or failed spark module
spark at top burner.	Low gas pressure
	No 120 VAC to range
	Micro switch contacts not closing
Burner will not ignite. No	Faulty wiring. Bad connection at burner
	electrode and electrode socket
spark to burner ignitors
when burner knob is rotated

position.

Correction

•Verify spark.

•Replace spark module.

•Verify pressure 4” WCP for natural, 10” WCP for LP.

•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.

•Replace electrode.

•Replace ignitor lead or electrode.

•Verify spark.

•Tighten ground connection and correct any breaks in ground path from ignitor path to unit ground path.

•Replace ignitor lead.

•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.
