Question:
I had my fridge for a year before the light changed and I had to change my filter. We use *TONS* of water and ice. The ice bucket used to fill up in a day and the water flow was adequate (but not exceptional).

Does anyone know if buying a new filter will solve this? It was expensive ($50) and is now 4 months old - I doubt the parts place will exchange it for me (BUT, the label does say it should last for 6 - 12 months, and the Green indicator light is still on).

Do you think I have a case to demand a new filter free of charge? What could be the problem if the new filter does not help increase the flow?

Answer: The amount of water should not effect ice production. It will harvest whenever it is ready whether water is in there or not. Unless the icemaker isn't filling *at all* at times (unlikely IMO), the water supply likely has nothing to do with reduced ice production.

if you're having a problem with reduced ice production (not reduced cube size), a more likely cause is reduced freezer temperature. Check and clean the condenser coils beneath the fridge as that is a major cause of reduced freezer temperature (and also increases energy consumption of the fridge)

There will be some reduced water pressure through the filter but if your "heavy water flow" is still not 'up to snuff', the filter will just make it worse.

Many water line installations will have a sediment screen in the water line where it attaches to the fridge's water fill valve. If it is partially plugged, it could be contributing to the problem.

Also, if a 'saddle valve' was installed on your house water pipe for the fridge's water supply, it could be partially plugged with lime and scale, etc. It will be even worse if a 'self piercing' type saddle valve was installed or any type of saddle valve was installed on the underside of a horizontal water pipe.
