Larry B for Model Number KSRA25FKSS00 Freezer fine plenty cold, frig warm, Evap not froze up fan running fine. Defrost and drain working right Seems like the damper closes after just an hr or less of run time and then does not open back up to send air into the refrig. section. The Sensor/Thermister is fairly new. How does it all work with the T-Stat and the board along with sensors. Sequence of operation. I really need to fix this.I tried to test the damper assy on my work bench. It will open and close with power to the right terminals. I wonder can it close on its own? I had changed the sensor about 1 mo. ago because the frig freezer was running way too cold. this did fix that problem. now 3 weeks later this new problem with the ref. section problem. Thanks larry B
Answer Hello Larry. The sensor communicates through the board to open the diffuser. If the sensor WP2188819 is new, then it sounds like the board 8201664 will need to be replaced in the unit. Read More... Answered by AppliancePartsPros.com | Wednesday, October 29, 2014
