Dan F for Model Number KSRT25CRMS01 Fridge not cold enough. Checked condenser fan - appears good, cleaned off condenser coils - were really dirty. Still not cooling fridge. Checked evaporator coils - not frosting over, also evaporator fan appears good - blowing good stream of air. Checked thermistor inside freezer and fridge - both around 3.3-3.7 ohms. Air diffuser damper closed - doesn't appear to open/respond to warm temps. Verified 115 VAC going to air diffuser motor. My troubleshooting leads to air diffuser as suspect. Do you concur?
Answer Dan, Yes we concur. If you have 115 VAC across the black(L1) and orange/black wires(N) then the diffuser motor should run in either direction. The WP2216112 Air Diffuser will need to be replaced. Read More... Answered by AppliancePartsPros.com | Wednesday, October 21, 2015
