My Jenn Air SVE47600 16 year old electric slide-in downdraft range has a hole (approx. 1.5" to 2" x 1") in the oven liner (underneath the broiler element) near a steam vent! Seems like it rusted. The insulation is exposed and singed. I discovered this while wiping the ash residue following use of the clean function. Obviously, I haven't used the oven since. Naturally, the oven body part is no longer available. Is it a fire hazard with the exposed insulation? Ironically, the oven and stove top are working fine.
