Fred for Model Number KSRS25ILB KitchenAid side by side, purchased 7/15/02. Fridge side running very cold, diffuser is just pouring in cold air from freezer, causing some Fridge side to freeze . Set Fridge side temperature control to max (41 deg), no change (diffuser air still full speed coming in from freezer side). I have had problems twice before with the diffuser, only the diffuser was iced up and no cooling to the Fridge side. I took the diffuser apart and found a broken plastic part. I glued a flat tooth pick to fix the part and put it back together (a pain). Lasted for 2-4 years each. Health has warn me down, so I would like to buy a new part this time – is it the same problem (diffuser)? So, are there any other known issues that can be causing the problem (for instance, could a temperature sensor be reading high and causing the diffuser to pour freezer cold air to the Fridge side)? Other ideas on what could be the problem? Thank you.
Answer Fred, The most common issue for your type of complaint, is a broken link on the diffuser damper door, or failed motor, and the door won't cycle open or close WP2216112 / WP2216112 Air Diffuser. Other checks to make are at the doors, make sure the doors close and seal properly, make sure the ice dispenser flapper closes and seals properly and articles on the shelves aren't hanging over the sides or against the walls blocking or redirecting the airflow.
