Bought a new gas range oven with electric oven heat element.

Manual recommends 50 Amps NEMA Type 14-50R dedicated circuit for all models.

But for this specific model requires a minimum of 30 Amps with 220 Volts, which is what I have. 3-pole, 4-conductor.

The power supply cord kit was not included so I had to purchase it.

Wired it up as per instructions.

Now, here is what happened.

When I turned on the oven the second or third time, the temperature sky rocketed to far beyond its limit (I presume in the range of 600-1000 degrees). It melted some of the metal.

And it hasn't worked since then.

Oven light and fan work. The gas stove work fine as always.

Only the heat element has gone bad.

Anything here that would indicate an error on my part?

any idea what the issue could be?

thanks for the help
