Look for a model number starting 111 on a bottom-freezer before trusting this meaning of rt. If it comes back, it needs a visit. ### Should I move my Kenmore Trio because it shows rt Lo or rt Hi? No, the fix is at the ambient sensor that reads the air around the refrigerator, not in the room itself. Its wiring and resistance are checked before it is changed. ### Could other codes be stored along with rt on my Kenmore 111? Yes, so keep stepping through the diagnostic list after rt to see what else is there. Bring the full list when you book. --- **[Read on the site: Kenmore refrigerator showing rt Lo or rt Hi](https://refrigeratorrepair.center/error-codes/kenmore-rt-111/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
