Questions & Answers

For Whirlpool Refrigerator Dispenser Micro Switch (Part Number: OEM18017667)

1 Answer

Hello Jerry, If the fans do not run you will probably need to replace the adaptive defrost control 4388932. If the fans are running you will need to pull the unit out and remove the start relay from the side of the compressor and shake it. If it rattles, it will need to be replaced to start the compressor. If the compressor is already running, you should remove the rear freezer wall and check the frost pattern. It should be even at least 3/4 of the way down. If there is frost an inch thick only on the very top of the evaporator coils, this is an indication of an air circulation problem. The air return into the bottom of the freezer section and on the fresh food side should be checked for obstructions. Also check the fan motor for normal full speed operation.

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.

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.
