Once I was convinced that the water supply and filter wasn't the problem, I took the back protective panel and looked at the valve assembly. It looked corroded, especially on top where the ?pistons for the solenoids?would project into. I ordered the part and it was on my doorstep in TWO days...really fast. The part was slightly different from the one that I was replacing in that the part was "angled out." This was not a problem. All that did was tilt the fitting for the copper water line connection out to make the connecting the line easier. Once I unscrewed the single screw holding the unit to the fridge, I simply slid it out and did a one-to-one transfer of the electric connections to the new assembly. Don't undo them all at once, or figuring out where the 8 wires connect could be confusing. Then I worked on the water lines. One-by one, I slid out the black C-washer on the water connection, pressed the flange "in" toward the unit to release the white plastic water tubing while gently pulling out on the tubing, and PRESTO...the tubing came out easily. I simply moved the water line to appropriate spot on the new unit, gently pushed the tube in as far as it would go and replaced the black C-ring to "lock" the flange. A gentle tug on the tubing convinced me that it was secure (and was water-tight when I turned on the water). Absolutely NO LEAKS. I pushed the unit back in (had to do some moving of the wires to assure they wouldn't interfere with the fan on the left), and then replaced the screw to hold the new assembly to the box. I replaced the copper water inlet tubing and I was done in about 15 minutes. I'd call this easy if you take your time and move the wires and tubing one-at-a-time. If you removed all the wires and tubes at once without marking them or taking pictures, I think it might be quite a job to figure out where each of the eight wires and four tubes goes. Don't let it worry you if your old unit is straight and the new one is angled. It will work just fine....
