Is this part a 2500W element?
Answer Hello Carl! Yes, the element 00241778 is a 2500w unit. Thanks.
Can I replace the convection heating element (AP3775599) myself or must I hire a service agent?
Answer Hi David. From the pictioral view, it can be accessible from the inside oven cavity. Remove the power. Remove all that would conflict with removal of the inner back panel. If you do remove the inner insulation while unhooking the wires from any elements, make sure that after it is reinstalled that you put the insulation back around the element so heat does not go out the back and burn any wires. The Convection /bake element is part # 00241778. Thank you.
