Welcome to the forum
If itís a suburban brand the element is underneath the plastic oval cover, located near the bottom left corner.
If itís an Atwood, the element is located on the back side of the unit. 1 1/2Ē socket is needed and itís a tight fit. Best thing is to take the old one out and match the wattage that should be stamped on the part. Be sure itís actually bad before spending all the time and effort.
