icemaker trough freezes up sometimes in Whirlpool fridge

[robert7]

This problem is with a Whirlpool side by side door fridge with the ice crusher and water dispenser in the freezer door.

I had a problem with the icemaker. Originally I thought the icemaker (4317943) was faulty, but it now works great.  I did all the tests online and on youtube.  The problem is that ice is forming on the trough that feeds the water to the ice tray.  I clear it out and it happens again, but only once in a while.

Water feeds in fine once the ice is cleared and the icemaker seems to function perfectly.

I'm thinking that the inlet valve is leaking sometimes and probably needs replacing.

There's a water dispenser with this model, so there are two solenoids that release the water.  The dispenser works fine.  I'm just concerned that I have to replace both solenoids to fix the problem with the leaking of the water into the icemaker.

Anyway, that's the question.  Am I correct that this is a solenoid or inlet valve problem?  Or could it be something else?  Can it be fixed or must I replace the double solenoid piece (4318046) ?

Thanks for any help.

If you have good water pressure to the refrigerator then I would replace the water inlet valve part # 4318046
