Product review (5 stars): Fits 10 year old GE Profile perfectly
Works perfectly with my GE Profile fridge (10 yrs + old). I think the key is proper installation. When inserting the new cartridge, make sure you press the nozzle end firmly into the fridge receptacle. You should feel it push in and then turn to screw the cartridge in but not too tight. Run the water dispenser for 2-3 minutes to get all the air out of the line and it should be good to go.
