Using top oven's grill, bang and a spray of sparks. Oven powered out, circuit breaker tripped, checked the top oven, grill element has warped and come into contact with the metal plate suspended above the element. Could this have shorted it out, more to the point, anyone think this might be fixable with a replacement element or might it be worse? Anyone know what the part number is, Model 482BL, serial number 29100144. Thanks.
