Thanks, all, for the replies. Apologies for the lack of specifics in the original note and taking so long to reply. I guess when I first asked the question, it was more a "what's your rule of thumb when attempting repairs yourself vs. calling a professional," especially when there's a possibility of burning down your house.
As for the details, it's a Frigidare Gallery Series glass-top freestanding electric range, not entirely sure on age (I'd estimate about 10 years old.) There are two burner problems. One doesn't work at all, and one has lost variable control (so it's either off or on high). I haven't opened it up yet but have researched on YouTube and found and watched the videos I'd be trying to follow. First to troubleshoot to determine if it's a switch problem or a burner problem, then to fix both types of issues. My initial instinct is it will be time consuming and more complicated than anything I've attempted. I don't come from a DIY background but am trying to develop more of these skills.
