Read the model plate; the FD code is decoded here for 111 bottom-freezer models only. If it comes back, it needs a visit. ### Is FD on my Kenmore Trio about the freezer door? No, FD Lo or FD Hi reports the freezer defrost sensor. Freezer door problems on this model show as dF. ### Why should I not wait on FD Lo or FD Hi on a Kenmore 111? The defrost sensor tells the control when the freezer coil is clear, and without it frost on the coil keeps building. Mention any frost you see on the back wall when you book. --- **[Read on the site: Kenmore refrigerator showing FD Lo or FD Hi](https://refrigeratorrepair.center/error-codes/kenmore-fd-111/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
