Customer Questions and Answers for Refrigerator Air Damper Assembly by Whirlpool

Hello Joe. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater WP2323197 and the defrost thermostat WPW10225581. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer 4388932. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hi Richard. Are both controls set mid-way only. If it is too cold in the freezer, then turn it back to 1/2 way setting (0°). Look at the back wall of the freezer. I noticed what you have changed. If the defrost heater is open (w/ohm meter), this part # is WP2323198.Please call 1-877-477-7278 A.P.P. Call Center. If the defrost timer is not allowing defrost then this part # is WPW10135091. All electronic controls are included in this board. Thank You.

Hi Tim. The control box/panel controls the panel and light. It is part # 2304102. The air diffusser is the air damper assembly that allows a certian amount of air is normally let into the fresh food from the freezer fan assembly. Then behind the crisper drawer is the air return duct as the normal SxS air circulation is clockwise. Thank you.

Hello Tim. You can use a flashlight to look inside the diffuser or you can feel with your hand and see if the cold air is coming out of the diffuser. Hope this helps.
