Thanks for taking the time to read my posting.

I have a Whirlpool Refrig with a built in freezer door water dispenser
and ice dispenser (crushed or cube).

The ice maker is working fine but the water dispenser stopped. I could
hear the hum of the water valve when the dispenser lever was pushed but
no water came out. So, I thought that part of the valve was bad and I
replaced the water valve with a new one. This is the valve that the
water supply attaches to and has two water outlets--one to the ice maker
and the other to the water dispenser. Well, that didn't cure the
problem. Still get the hum when the dispenser lever is pushed but no
water comes out. I checked the water outlet tube in the door as far as
I could see and it is not obstructed.

From the water valve located at the bottom left of the refrig that
water line enters the bottom of the refrig and comes back out at the
same spot in a smaller diameter plastic tube. It then goes to the
bottom of the freezer door and upward to the water dispenser. Since the
main water valve is good and the dispenser switch is good I feel there
must be an obstruction somewhere between the water valve and the outlet
tube. Anyone know where this could be or what the problem is ??? There
are no leaks anywhere and absolutely no water comes out of the dispenser
tube.
Any assistance will be appreciated. The refig is about 5 years old and
has had no other problems.
