I think this link will take you to a PDF for your model.
http://genet.geappliances.com/DocSea...f/49600212.PDF Please be sure this is a match with your fridge before relying on it for info. If this is the correct manual see page 9 for filter info. If you need the FXRC or FXRT filter they are no longer made, but you can find an alternative replacement at the following link
http://www.waterfilters.net/GE-MWF-R...r_p_0-329.html You will need to purchase the adapter, but this can be reused and will not need replacing each time you replace the filter.
Thank you,
