Customer Questions and Answers for Damper Control by Whirlpool

Joe, the damper control assembly should not be so loud that it can be heard from several rooms away. Replacing it should improve the noise level.

Belen, the damper assembly for your model is [WPW10129864].

Hello Al, We will actually need you to please post a new question including the model number from the units' I.D. tag. This will allow us to see the exact configuration machine you have in your home. While it is still difficult to determine where the unit is leaking without being there, we can point out possible places where a leak can occur. The best way to locate a leak is by opening the unit and using a strong flashlight to locate a "water trail". You see, when a washer leaks, it does not leak pure water, but soapy water. There are normally mineral deposits also in the water. When the water evaporates, these impurities do not. They remain, leaving a trail up to where the leak originated. A strong flashlight will make them show up as a dull, sometimes white, line leading all the way to where the water exited the machine. As a technician, this is how I have located leaks over the past 30 years and can honestly say it is the best way to locate leaks since the water trails do not lie.

Mick, the damper should only open and close based on how much the refrigerator needs to cool down. If it is opening and closing non stop, you can test the thermistor to see if it is reading properly, but there is a chance that the control is the issue itself. The thermistor can be tested by testing for resistance.

David, it sounds like you have a defrost control issue. Take a look at the back panel of the freezer section and see it it is covered with ice..You will need to defrost the coils if they are iced up and then replace the defrost control that is located in the control panel, part number is WPW10503278

Dennis, After changing the damper control give 24 hours to get the unit to the correct temp.

Harvey, The damper should not be opening and closing every 10 seconds. It will stay open til it reaches proper temp then will close.

Gary, This type of issue would be more likely an air leak from outside the unit causing condensation that is building up and freezing the air ducts. You will want to check the door seals and the dispenser door to make sure that they do not have air leaks. As far as removing the damper control you would remove the cover over the damper and in the freezer remove the icemaker and the duct at the top of the unit that goes to the icemaker. There will be 4 tabs you have to release in the corner for the damper control to come out of the unit.

Tom, the model number you supplied is for a Frigidaire "french door" refrigerator. The "SY EF" error code indicates a problem with the evaporator fan in the freezer compartment. The evaporator fan operates on 8 to 12 VDC. You may want to start at the control board on the bottom of the refrigerator ans see if you have the DC voltage out of the board to the fan, or vice versa, to determine where the issue is.

Thing to fix it, If the damper had ice on it, then this would cause the damper from opening and closing. The temp that the damper should open is when the unit gets warm enough in the refrigerator section which should be around 40 degrees and close when it gets to about 36 degrees. This issue could be caused by a faulty thermistor which is located under the controls.
