Hi, you can replace it from within the grill. There are four screws that hold the back panel in. Once removed it reveals the element. A single screw holds the element in place and when removed you can pull the element out and pull off the two push on crimps that supply power to it. MAKE SURE YOU HAVE DISCONNECTED THE OVEN FROM THE MAINS BEFORE ATTEMPTING THIS.
