Right on Tom!
The heating element is usually located in the boiler section, which is the cylindrical tube normally found on the right side of this fridge. Follow the 2 black wires from the board and they will lead you to the element.
Remove the outer sheet metal cover to the boiler and the element should come out vertically. It may be stuck, so a twisting motion will help extract it. If you are going to clean the boiler section, including the very important spiral baffle which is suspended from the top of the chimney by a wire, you will have to take the unit out for complete access.
Once you remove the baffle, clean it with a wire brush but be careful not to distort it or the wire that holds it in place. Remove the burner from the bottom and then get a chimney brush and swab the rust from the inside of the chimney. be sure to vacuum up all of the rust that falls to the bottom.
Re-assemble everything, replace the unit and you are good to go!
