How to Test an Icemaker Water Inlet Valve

Water Inlet Valve

Water Inlet Valve. Dual outlet water valve used on some Whirlpool/Kenmore brands refrigerators with water dispensers and ice makers.

Testing your Icemakers Water Inlet Valve is not a common appliance occurrence. However some of the most common Icemaker problems do involve the Water Inlet Valve. So, we thought it would be a good idea for you to know how to safely test your Water Inlet Valve!

“What the heck is a water inlet valve?”

A Water Inlet Valve  is an electro-mechanical valve that opens to supply water to either the icemaker or water dispenser. The Valve is located at the rear – lower end of the refrigerator.

You may need to test your Water Inlet Valve if your Icemaker

  • Is not making ice
  • Ice  is too large/small
  • Ice tastes bad
  • Ice is discolored
  • Water is leaking from the unit


  • Pliers
  • Multi-meter
  • Bucket (optional)
  • Rag (optional)


  1. Set the multi-meter to the lowest setting for Ohms of resistance. For an Analog Meter, you will be to calibrate it by holding the metal tips of the black and ref probes together while adjusting the needle to read zero.
  2. Remove the Water Inlet Valve from the back of the refrigerator
  3. Disconnect the supply lines to the valve. You may want to keep a bucket near by to catch any excess water that may spill out of the water supply line.
  4. Remove the screws securing the valve to the refrigerator.
  5. Using Pliers, remove the wire harness connecting to the terminals on the Water Inlet Valve. Be sure to label the placement of the wires before disconnecting them.
  6. Set the multi-meter to R X 1 ohms to test for continuity. Areas of the part should be marked for testing. Refer to your owner’s manual to be sure that you are testing the right area.
  7. Touch one multi-meter probe to one terminal and the other probe to the other terminal.
  8. Depending on your part, your readings can be from 200 and 500 ohms, or for refrigerators with both a water and ice dispenser, the ohms of resistance might be higher – 500 – 1500 ohms of resistance.

If your Water Inlet Valve did not reach these levels of continuity, the part will need to be replaced.

  1. When I took readings of my old water inlet valve, I got .311 on the blue solenoid and 172.6 on the red using an automatic ranging multimeter. Bought a new double solenoid and it’s readings were identical. Why are my readings no where near what you are suggesting they should be?
