My range is 15 years old. Range top gas burners and gas broiler all work, but the gas bake function is not happening. i'd like to DYI a fix if I can with your guidance and parts, please.

Also, the oven door has recently, and suddenly, begun to clunk and scrape as I open and close it. The noise and friction seem to be coming from behind the slit in which the right cast curved hinge piece travels. Noticed also that the right 4" of the bottom of the oven door rubs against the stainless horizontal top of the warming drawer as the oven door opens and closes. As far as I know, there hasn't been any trauma inflicted on the door. Can I fix this, too? Are the two problems related?

Thanks for any help or advice!

Dave
