Customer Questions and Answers for Damper Control by Whirlpool

Hello Ron. Based on the information you provided, the damper WP67003903 is working fine on the unit. It shouldn't close all the way on the unit. This is for air circulation in the unit.

Tim, Roll the freezer drawer out as far as possible and check for a frost or ice build up on the back wall of the freezer, you may have a defrost issue. Another thing to check is the evaporator fan motor WPW10128551 , it moves the air through the freezer and up into the fresh food compartment, and remove the crisper drawers in the refrigerator, and check the air return tunnels in the bottom corners of the compartment for blockage or ice. Of course you're also going to check and make sure all the doors close and seal all the way around the opening. Thanks and Good Luck

Surinder, You have a "sticky" auto damper, great diagnosis, there are two different damper assemblies depending on the first two numbers of your serial number on the unit. If your serial number starts with 10 you will need WP67003903 If your serial number starts with 11 or higher WPW10196393 is the damper assembly you will need. You'll be fine once you get that control replaced. Thanks and Good Luck

Hello Terry. If the noise is in the freezer, you will need to replace the evaporator fan motor WPW10128551. Hope this helps.

Hello Alfred. If the damper is good and the thermistor is good, you will need to replace the control board WPW10503278. Hope this helps.

Hello Mark. You will need to check the evaporator fan motor 12002744 and make sure it is running properly. The evaporator fan motor is located inside the freezer section of the refrigerator. If it is running properly, make sure there is no defrost problem inside the freezer. If it is good, you will need to check the damper WP67003903 inside the refrigerator and see if it is stuck closed. Hope this helps.

Hello Jason! Is the freezer back wall building up with ice? If so, you may have a defrost control issue. The defrost is controlled by the defrost heater WP67001794, defrost thermostat 12001937, and the electronic board WPW10503278. If you have the tech data sheet it will have information on how to run the diagnostics on the unit. Hope this information helps you!

Check and see if your fan is running in the freezer. If it is, then you will need the damper assembly, if it is not opening.
