Customer Questions and Answers for Diffuser (Refrigerator Air Damper) by Whirlpool

Hello Mike. Check and see if the diffuser is stuck closed or has power to it and does not open. If so, replace the part. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello Kris, Several things could cause this issue. If there is an air leak and a frost build-up is accumulating around the damper door 61003235, it may be remaining open. If so, the air leak at the ice door or around one of the door seals will need to be corrected. The next possible cause would be a defective auto damper assembly 61005989. If this does not appear to be the cause, the temperature control WP61005516 may be defective.

Frank, To replace the diffuser in your refrigerator you will need to clear the top shelf of the refrigerator. On the left side wall there is a screw in the long piece between the diffuser and the control panel. Remove the screw and take that piece down. Then on the diffuser cover there will be another screw, remove it and diffuser cover. Then you will want to open the freezer door and take off the ice door and on the bottom of the right side of where the icemaker is there is a 1/4" screw. You will take out the screw and remove the cover over the wires of the icemaker that the screw was holding in place. Pull the icemaker out and disconnect the harness. At the top of the freezer there will be 2 screws for the icemaker ducting. Remove the screw and the ducting. Once this ducting is removed, on the right side wall you will see where the diffuser comes in. Push the corner tabs toward the center of the hole to release the diffuser. Reach into the refrigerator compartment and pull the diffuser out. There is a rod that connects to the diffuser that you have to turn the diffuser to a certain point to release the rod. You will remove the temperature probe that goes around the face and install the new part and reassemble. We also would not have any information on servicers or cost in your area as we are a parts supplier.

Hello Jose. To remove the diffuser you will remove the screw on the cover of the diffuser. Once this is removed then you will open the freezer door. Take the door off the icemaker cover. Under the... more icemaker there is a 1/4" screw to remove. Once removed then take the cover off the wire harness this is where you just took the screw out. Push in on flapper and pull the icemaker out. Remove the 2 screws holding the air duct on the ceiling out. Once this is done pull out the air duct. There will be a clip on each corner of the air duct. Push them toward the center of the diffuser and pull out of other side. Reinstall in reverse.

Raymond, You will want to check the vent down by the upper drawer in the refrigerator compartment to see if it is full of ice. If so it will need to be cleared and it would also be caused by moisture getting into the refrigerator compartment. Check for bad seal or air migration.

Hello Luis, The diffuser motor is a 120Vac component.

Mando, you want to check the air return tunnel on the side of the refrigerator wall, make sure its not blocked by a package or something similar, or has collapsed on the inside. A model number would've been a big help, we could have been a bit more helpful. Check and make sure you don't have a defrost issue (heavy frost or ice on the back wall of the freezer compartment.

Hello Jim. I think your problem will be solved by replacing the diffuser assembly. I think the issue is associated with the sensor on the diffuser assembly W10899382. I hope this helps solve your issue and have a great day!
