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

Hello Donald. You will need to check and see if the terminals have clips that attach the wires to the micro-switch WP2162361. If so, you will need to use an ice pick to release the clips and pull the wires off the switch. If not, the wires will pull off the switch. These can be tight. Hope this helps.

Hi Barry. Has it been more than 6-mos. since that you changed your water filter? This will clog, bypass through the head assembly and flow up into your water tubing. So, try changing the water filter part # is EDR5RXD1. If you have already changed this then I would consider changing the micro switch connected to the paddle assembly. The micro switch part # is WP2162361. Thank you.

Hello Joe. You will need to adjust the paddle where it will make contact with the switch. If it does not adjust, you will need to replace the micro-switch WP2162361. Hope this helps.

Hello Dave. We do not offer any diagrams of how to install this part. You will need to remove the front dispenser cover by unsnapping it off the freezer door. Then you will see the screws to remove the dispenser housing. Once the dispenser housing is removed, you will be able to access the microswitch. Hope this helps.

JJS, your wiring diagram / tech data sheet, is located behing the grille kick plate on the front of the refrigerator, it's usually rolled up like a news paper. Based on your description, sounds like youve got a loose connection on your water dispenser switch or wire harness is damaged ? The Blue/Black wire is power into the switches and cavity light. Purple wire is power out to the fill valve and Yellow/Black is power to the cavity light, Remeber this is 120 VAC, so be careful when you're testing. Thanks and good Luck

Hello JJS. If there is power at the switch, but it is not sending it to the valve, then it sounds like the switch is bad. Check and make sure there are no broken wires from the switch to the valve. Hope this helps.

Hello JB. Check at the valve, when the dispenser is pressed, and see if your getting voltage to the valve. If no voltage is present, the switch may be bad. Hope this helps.

Hello Stephen. You can check and see if the switch is sticking. If it is ok, you may have a bad water valve W10408179 not shutting off. Hope this helps.

Kenric, have you checked the water inlet valve W10408179? A defective valve will cause the unit to not dispense water. Hope this helps!
