Larry for Model Number KFIS29PBMS00 The refrigerator is not cooling sufficiently. There is an upper coil in the refrigerator section that has ice buildup yet the lower coil (in freezer section) is fine. I replaced the evaporator fan which includes the thermostat for the lower coil. Still not cooling in the refrigerator compartment. How does the cool air get into the refrigerator section? The lower drawer in the refrigerator section cools great as it appears to get air from the freezer section below fine. It seems like there is no air flow to the refrigerator. We thawed the upper coil so no ice build up, but still "frosty". Any ideas what may be wrong? Thank you
Answer Hello Larry, The freezer and fresh food compartment do not share air in this design unit. The unit has separate evaporator coils and they should take turns with the compressor pumping Freon into these evaporators. The part responsible for sending the Freon to one or the other evaporator is the three way solenoid valve WPW10364560. This is the part I would first suspect. Read More...
