Hello and thanks for using JA!

My name is ***** ***** I have been repairing appliances for over 40 yrs and I will be assisting you tonight in trying to find out why your appliance is not working. Sometimes, there will be lapses in my replies back to your because of the volume of questions I am answering. But, please be assured that I will be giving you my best effort to help solve your problem.

If the solenoid is hot, that would indicate that you have voltage trying to energize the valve. But, you would need to confirm that by measuring the voltage to the coil when it is calling for water.

If you determine that the coil is live, then remove the output line on the water valve and see if anything is coming out. If you get no water or very little water, you have a bad valve or a clogged up valve. There is a small restrictor orifice inside the valve that throttles down the water flow to a trickle to flow over the evaporator plates. You may or may not be able to clean the valve depending on how it is constructed. Check those things out and tell me what you find.
