I have a PSS25MGMBWW refrigerator. Over the last several weeks, the ice cubes in the collection bin freeze together. The auger motor and the solenoid that switches from cubed to crushed ice freeze up. There are frozen droplets in the upper part of the freezer. I've taken out the ice dispenser, thawed and dried it well, and reinstalled. **It works fine for 3 or 4 days, then it freezes up again.

I've cleaned the condenser, replaced the defrost thermostat, and confirmed continuity in the defrost heater. The door seal looks okay, so I have not replaced it (yet). Suggestions? **

Thanks...
