Kenmore model 4783 wall over / Heating element fire

Another Kenmore oven heating element fire. We have the Kenmore 4783 wall oven, installed about a year ago, the oven is close to two years old.

Same story - when heating at 350 degrees, the heater element failed and caught fire. My wife was in the kitchen and turned off the oven right away and the flames went out after a few seconds. Having read all of the complaints on this site, I worry about simply repairing and replacing the heating element as it seems to recur for some people. Not sure if this is related, but the oven has always cooked about 15 degrees low. For something that requires 350, we've had to cook at 365.
