Dual Cold Water Valve

Hello Ted, Thank you for the question. If the Water Valve is defective it will not send water to the dispenser or enough water pressure to fill the tray. The valve can be tested with a Multimeter. Set your multitester to the ohms resistance scale X 1. Place each of the meter's probes to one terminal. Because the reading can vary from brand to brand and from model to model, there is no one reading you should receive. However, if your test produces a reading of infinity, then the solenoid is bad and the water valve should be replaced. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!
