My dog had no qualms about gnawing on the corners of his Coolaroo.
That said, it was much easier to deter him from chewing it with this than it was to deter him from chewing on a bed with stuffing.
Have you looked into this? It's made from apple bitters so it's safe and non-toxic, but it tastes HORRIBLE and smells very bitter and pungent if you get up close (i.e. your ferret would smell it right at the stove, but you wouldn't). If you do try it, do not just spray is at the offending area, it will diffuse through the air and you will taste it for days. Saturate a paper towel and wipe down the front of the stove and the area in front of it.
My dorm apartment stove had the bottom drawer, so I duct taped pieces of pizza box cardboard (the narrow edges) to the bottom of the drawer, but not to the floor, so they moved with the drawer, and then coated it in bitter spray, which the ferret I was babysitting at the time got grossed out by as he was trying to dig away the cardboard. So, maybe consider blocking it until your fuzzy learns to not want to play there?
This is the one I bought. Be very careful to only get it where you want it if you decide to try it. https://smile.amazon.com/gp/product/B0002DIOD0/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
