The Micro Switch is an OEM part for Whirlpool refrigerators that is responsible for controlling the ice and water dispenser. The switch operates by responding to mechanical actions, like the pressing of the dispenser paddle or button to open or close to allow water and ice to be dispensed. 

Symptoms of a bad Micro Switch include:

  • The ice or water dispenser not functioning  
  • Intermittent operation of the dispenser 
  • Stuck dispenser preventing ice or water from stopping

Causes of a bad Micro Switch can include physical damage from heavy use, wear and tear over time, or electrical issues such as short circuits that impair the switch's function.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

Questions & Answers

For Whirlpool Micro Switch (Part Number: OEM18017667)

1 Answer

Johnny, The next thing to check or replace would be the filter housing WP2186443. If you're sure you have the correct water filter, and it is properly installed in the present housing, then the issue would be in the internal valve system in the filter housing.

Gary, You will want to check to make sure that the water filter is good and also check to make sure that the water valve is getting power to the valve when activated.

Ajay, At the bottom of the door there is a water connection. Disconnect the water line and push the dispenser and see if the water comes out. If water comes out then the water line in the door is frozen and is not a replaceable part. The door which has been discontinued would need to be replaced.

Rick, You will want to check the dispenser bracket for broken pegs where the switch is located. You do this by using a flat blade under the lower front of the dispenser panel and pop the lower part out. Once out you can take the panel off and inspect the bracket.

Sam for Model Number ED5FHEXNS02

Hi, My water dispenser is not working, however ice dispenser is working. I thought the micro switch was broken so, I switched them around between ice dispenser and water dispenser. The ice dispenser still works but water dispenser does not. I hear the click noise when I hold the lever, so the lever is pushing the switch on micro switch. I saw the water flowing from back of the refrigerator when the ice maker is turned on. We always keep it off as we rarely use it. What could be the problem here? Thank you, Sam

Hello Sam, This sounds like the water line in the door and/or the water reservoir in the bottom of the fresh food section has frozen. You can try turning the freezer temperature setting to a warmer setting and the fresh food setting to a colder setting. This will increase the air circulation throughout the unit and stop the cold air from "migrating" to the bottom. When you do this, you need to let the units' temperature stabilize for 24 hours before attempting to dispense water. If this isn't fast enough for you, you can remove a crisper drawer and heat the water reservoir with a hair dryer.
