If you have a slight amount of mechanical aptitude this is a really easy fix. I just propped open the stove top on which the burners are seated, removed wiring to old sparking ignitors, removed ignitors, and replaced with new ones. Voila! Burners spark and ignite as before.
While I was only having a problem with one burner not lighting, I decided the other one would be close behind to fail. So with the ignitors being only $22 each I decided to order two of them and replace both while I was in there. I replaced the two other burner ignitors 18 months ago so I tackled the learning curve thus making this time a true cake walk.
There's definitely not a need to call in a professional for this type of repair as AppliancePartsPros empowers the homeowner to DIY !
