Help! Electric stove/range throwing out unusual amount of heat

Our Whirlpool electric range oven with glass cooktop was recently moved out to get at the wall behind it, then it was put back into place. The next time I used the oven, I noticed the kitchen heating up significantly more than normal. By significantly, I mean Death Valley territory. The rangetop area was extremely hot, though the cooktop surface itself was not hot to the touch, and had no elements turned on.
The heat was definitely coming from the oven compartment, rising into and exiting from the upright back portion of the stove, in the space just beneath the control knobs. In that space, which I believe is the area intended for normal venting, there's a metal thingamabob showing that wasn't there before. My guess is that it's a part that got sprung during the moving of the stove, and that it's the culprit.

Since this metal thingamabob, whatever it is, could pop out of place so easily with simply moving the range a few feet, I'm hoping it can pop back just as easily and all will be well again. But I have no experience in remedial thingamabob popping and would like to have some knowledge of what I'm doing before blindly poking at it with a butter knife. (Just so you know, I do have enough sense to unplug it before attempting anything. Yeah, I heard you worrying about me. Thanks, that was sweet.)
I can use the cooktop without problems. But the oven is unusable this way, not to mention there's a natural concern about safety issues. Anyone know what the deal is here and if it's something that can be fixed without a repairman? Thanks!
