Yes, but what would make a cord fail 12-24" from the connection?? very odd phenomena. I'm sure it happens. Maybe when they jammed stove back in it got pinched/nicked ? but that some really thick stove cord insulation though

Heat, time, pressure, sharp metal edges... You only need three of those to make a diamond... and 4 to turn a range cord into elemental carbon

Also note from the burnt area it melted 4" one way and 12" the other way. perfectly grey no burn marks just melted flat makes me think it was pretty high temp for long time but not too high to cause burn marks all the way along 1' section ??

I am much less interested in the cable, and much more interested in why you are standing in black socks taking this picture. :D

Those are not just "black socks" ...those are 97% wool black socks with a green stripe in them. Very different

:lol:

The range cord got pinched somehow on or near the blower motor. It heated up the cord, melted the plastic, and sharp metal edges and minor vibrations took care of the rest. Heat alone might have done it.

They're lucky that 2 pole FPE breaker tripped. from what I have seen and read about them, I would be replacing that breaker as well... The two pole Breakers were notorious for jamming the common trip mechanism, and when reset, a good number of them will never trip again.

Cord too long? Outlet in wrong spot? Cord on my stove has a spring to pull it into an area as you push the stove in... to try to keep it from being pinched..
directions call for outlet to be within an area basically centered on stove or up to 8 inches off center, and no less than four inches no higher than 12 inches for clearance along with the note that one can pull the heating drawer to access this area if needed ...
uk stove has directions that show piece on top as keeping space for plug .. basically..the top extends over the back to keep an empty area behind the stove.. warning paperwork says be careful when pushing into place as pinching the wire can cause a fire later... due to damaged cable.
 
Worse case:
electrocution, involuntary man slaughter, prison time, big bubba as a cell mate.

If an installer comes out to a house with a new 4 wire stove and the house only has a 3 wire se cable. Then he just puts a 3 wire cord on stove and barely bonds the neutral to the ground screw whats the worst that could happen??

What are the four wires for. My understanding is that your domestic supply is 120-0-120. That accounts for three current conductors. So what is the fourth for?
Just curious.

So just three current carrying conductors - kinda what I thought.

Yup. In specifying US cable and flexible cord there are different conventions depending on cable/cord type as to whether
the Ground (PE) wire is counted or not. For plugs and receptacles it is always counted AFAIK.

Blower for "downdraft" exhaust system? May have been a fire inside blower housing and that melted the cord?

Circuit board with blown components is a surge protection device, it appears to have had too high voltage for too long across it. The transients it is intended to protect from can be fairly high voltage but typically for very short duration. couple thousand volts for just milliseconds it can take, 240 volts for several minutes it can't take.
