On this new model and my previous GE model, I wanted more space for jars on the door shelves. In 2001 and and 2016, I ordered an additional deep shelf for the express purpose of having more room for jars, bottles, etc., on the FF Door. It has been exactly what I wanted for the last 15 years, and now it is exactly the solution to the new model.
The part was ordered easily and arrived within 2-3 days. Perfect!
