Once i confirmed the cause of the problem was a bad switch, i found the exact part needed to replace it at appliancepartspros. received the part in just a couple of days, and was able to open the back of the stove and remove the old switch by unscrewing a bunch of phillips head screws, plugged the new switch in, and all works perfectly now. no need for an electrician or a new stove. i'm glad i figured this out on my own and saved a bunch by fixing it myself.
