Roger for Model Number Kitchernaid KSRS27ILWH01 Freezer side -20 C / refer side 5-10 C. Digital settings are set at 0 / 36. Diffuser is iced over with some condensation below diffuser on refer side. Vegetables are freezing in the veg crisper and in lower shelves of refer side. Lower refer side vent is open and air current is cold and hand detectable. Meat lowest bin vent stuck in "MEAT" slider selection and iced over. Main computer control board will not respond to "Power" on/off and computer will not allow me to set and enter diagnostic mode after multi[ple disconnects and attempts. Please advise. I believe I need a new main computer board, a defrost thermometer, and possibly a new diffuser.
Answer Hi Roger. Sounds like the diffuser WP2216112 isn't closing. First check for an air leak around the door seals and at the ice door [8201649]. An air leak will cause moisture from the air (humidity) to condense in the diffuser area and it could be blocked open by frost. If no air leak is detected you either have a bad diffuser or, since you have replaced the thermistor, the control 8201658 could be bad. Before you replace the control, unplug the unit for 10 minutes then reconnect to the power supply and see if it resets the microprocessor. Thank You. Read More...
