Randy for Model Number PSS27NGWAWW I suspect that my damper is stuck open because many things are freezing in the fresh food side; however, I don't know that it's not the thermistor. What is the best way to diagnose if the damper is stuck open? Should I just disassemble and check? Can I raise the temp on the fresh food side to see if the temp changes? Thanks
Answer Randy, Yes, you could reset the control to a warmer temperature and see if the temperature changes, but give it 24 to 48 hours to adjust and the temperature equalizes. Thermistors usually don't "fail" so I would start by checking the damper assembly, as long as you're sure theres nothing blocking the thermistor covers and the air flow around the shelves is OK, if the temperature does reset. here's some basic help "The fresh food compartment fan is located under the upper ductwork in the fresh food compartment. This fan distributes cold air from the freezer via the mullion damper. The mullion damper is located in the same assembly as the fan. Both are controlled by the processor. 1. Remove the deli fresh adjusting knob and light cover. 2. Unlock the upper and lower locking tabs for the center ductwork and remove. The ductwork is also fastened with double-sided tape at the upper and lower portions. 3. Remove the upper water filter cover. 4. Unlock the upper opaque light cover tabs and remove the cover. 5. Unlock the upper ductwork tabs and remove it.6. Remove the Phillips head screws (8) for the upper light assembly plastic bracket. 7. Pull the stainless steel light bracket down until the wires are exposed and disconnect them. 8. Remove the Phillips head screws (2) for the fresh food fan and damper cover and remove the cover.9. Lay the fan and damper assembly against the compartment and open the back cover. 10. Disconnect the wire connections and remove the damper or fan." Thanks and Good Luck Read More...
