I have a GE refrigerator that is 4 years old. Last week, when using the water dispenser, it started making a vibrating noise and water flow slowed to a trickle. I removed the filter and installed the bypass. No change. There isnt any air in the system as this is a filter that has been used and working fine for the past six months. I verified that the water reservoir wasn't frozen or freezing. So I assumed that it was water hammer caused by the water valve and ordered a new one. The part arrived and I installed it today, but it did not resolve the problem. I'm out of ideas and need help diagnosing this problem.

Two weeks and not one single person has any ideas that can help me!?! Not even a single response from the "professionals" at AppliancePartsPros. So much for "Your Questions Answered by the Pros!" I'll be sure to take my business somewhere else to someone who wants it.
