You will not be able to access that solenoid from the front. As you are looking at the fridge from the front, ( if it is the same as the 38FL ) it is on the bottom left in the rear. If you are going to pull the fridge out, you can just unplug the electrical connection from the solenoid and make sure the water is drained out of the line. You can only use the push type ball valve ( Mur-lok RO Inline Ball Valve Push Connect - Bulk Reef Supply
) ( this is the exact one I used ) if you are changing out the solenoid, because the water line is a screw on fixture on the original. The replacement solenoids ( which I REALLY didn't want to be introduced to ) have a push on type fixture, so when I trade in the rv, I can reattach the water line.
I can also winterize the water line going to the ball valve super easily. I use the antifreeze to flush the toilet during the winter months so we can stay overnight if we want to.
