I have a GE fridge (model GSH25JFRE) and the water from the dispenser will not get very cold. It is basically the same temperature as the water from the tap. I put a glass of water in the fridge overnight and checked the temperature against the temperature of the water out of the dispenser and the dispenser is about 15 degrees warmer. Fridge is definitely cold enough to produce cold water, but for some reason it just isn't working! Any ideas?
