For Whirlpool Spark Ignition Switch (Part Number: AP2921674)

Answer or Comment

The right rear burner does not ignite. Although gas comes to the unit the normal clicking sound emitted from turning the valve on does not sound. This sound is present on the other three burners and they operate normally, just the rear right is not lighting. Does the spark ignition switch need replacement? If not, can you recommend how to fix the burner to ignite. Thank you. Also, can I repaint the grates to return the luster to the part? Do you sell a high temperature paint for this purpose. Again, thank you.

ANSWER Jacqueline, You're on track, it's most likely a damaged, inoperable igniter switch. Does the rear burner igniter arc when you turn one of the other burners on ? If it does not arc under any condition, then it's a spark module or wiring issue 3186576 . Thanks

ANSWER Hello Jacqueline. First check for a lost ground to that burner. I usually loosen and re-tighten all the screws first. If this doesn't do it, either the spark switch 4168745 or the spark module 3186576 has failed. As far as painting the grates, this wouldn't work out well at all. The "paint" from the factory is actually enamel which is baked on at the factory at about 900°F. The only thing I could suggest is to buy new grates 3179106 for looks and always use the old grates when you cook. Hope this helps!
