Thanks for the photos and for already cleaning and drying the igniters. That rules out the most common cause, so we can narrow it down quickly.
What is normal and what isn’t
On the Whirlpool WFGS5030RZ0 (and most gas ranges), all four or five igniters spark together whenever any knob is in the LITE position. They share one spark module, so seeing every igniter click while you light one burner is normal.
What is not normal is the sparking continuing after the flame is lit and the knob has been turned past LITE to a cooking setting. Your range doesn’t re-ignite automatically, so the clicking should stop as soon as the knob leaves LITE.
Narrow it down in 2 minutes
- Take off the clear knob covers for the test. Covers that sit tight can keep a knob from turning fully out of the LITE position.
- Light each burner one at a time and turn the knob to HI.
- If the clicking continues with only one particular knob, that knob’s igniter switch is stuck. The switch sits on the gas valve stem behind the knob and is a common, inexpensive part.
- If it continues with every knob, the cause is more likely the spark module or a shorted wire in the switch harness under the cooktop.
- Note whether it happens only after cleaning or boil-overs. Liquid that runs down a valve stem into a switch causes exactly this symptom and can take a day or two to dry out.
Your range is almost certainly under warranty
At under a year old, this range is covered by Whirlpool’s 1-year limited warranty for parts and labor. Don’t open the cooktop yourself. Call Whirlpool with the model and serial number from your photo and ask for a warranty service visit. The fix is usually an igniter switch or the spark module, and both are covered.
Until then, the range is safe to use, but constant sparking wears out the module. If you ever smell gas, turn every knob off, open a window and call your gas utility.
