Burner heats up when oven is on

We noticed today that one rear burner gets VERY hot when the oven is used (you can feel the heat radiating from the burner itself). No the burner wasn’t on - I checked! Does this sound fixable and what is the average life expectancy of whirlpool oven ranges?

Need a Model Number

If the element was not on then this is probably the burner which has the vent from the oven under it. In which case it is normal.

Model # RS6305XYW6 Whirlpool oven

Thanks so much for your reply - we do see a vent back there. I just can’t believe we haven’t noticed this in 3 years, not sure if something is different or not.
