By far the most common part to fail is the oven ignitor. It's an electrical part attached to the burner that lights the burner. Even when they look like should be working ( glowing red ) they can be too high of resitance to let the gas valve open. They cost in the $50.00 range . Give model # XXXXX stove and I'll look up the cheapest place to purchase it.
Thank you for your response. The model number for my Gas Range is Maytag MGR5870ADW. If you could provide me with the part number for the ignitor, and where I could purchase it, that would be a big help. I live in Groton, MA and work in Everett, MA.
Here's the cheapest place I found www.partselect.com their part number is XXXXX $40.00 Thanks for using justanswer
