I seared the web and found Appliance Parts Pros site and when I input my GE refrigerator model number I was able to do some diagnostics on their site. It was indicated from my research that the Water Inlet valve most likely was at fault for my problems. I ordered the replacement valve from them and they shipped the same day as the order and it arrived the next day, faster than I had expected. I viewed their video and it was very good at explaining what I had to do to replace the valve on my unit. Simple and easy. I disassembled the access panel and was able to put in the new valve in about 20 minutes, easy to cautiously following the steps provided and reactivated the frig but still no water flow at the dispenser or the ice maker. Reviewed the actions taken and could not find any thing wrong with what was done. Disconnected the water supply tube and made sure there was a good flow from the input tube to the filter assembly, . Thought maybe the new filter was defective so put in the bypass plug in the filters place and still had no positive results. Tried to take off the assembly where the filter is put in place and that took some time since working inside the frig was cumbersome and difficult to reach, never did get it completely out of the space to examine it so I re-screwed it in place after a lot of jostling about. Replaced the bypass piece and low and behold water started to flow. Since when replacing a filter there is no water flowing out of the place of attachment I suspect that there may be a check valve of sorts in the fixture which may have become stuck and when I played with it trying to get the unit out I must have caused it to free up and allow the water move through the tube to reach the valve. Heard the solenoid on the water valve click and water was again coming out of the dispenser. Removed the bypass plug and put the primed new filter in and all went well, the water flowed freely and the ice maker cycled. All is running well and even though I spent several hours playing with the 7 year old frig I am now satisfied that all will continue. When I originally bought the frig I had purchased a 5 year maintenance policy covering parts and labor but that ran out about 18 months ago so any parts and expense for repairs could be lots. Thanks to the computer information provided by Parts Pro and the excellent prices I saved quite a bit on labor (minimal service call charges for a local technician to come and look at the problem for a visit and 1 hr are $100 and then you can add to that his parts needs and more charges for work)
