What FD Lo or FD Hi
actually means.
FD Lo or FD Hi on a 111 Trio says the freezer defrost sensor has failed. That sensor tells the control when the freezer coil is clear of frost; Sears checks its wiring and then its resistance, which should fall between 8,000 and 40,000 ohms.

Read the model plate; the FD code is decoded here for 111 bottom-freezer models only.
Look at the freezer's back wall for a build-up of frost and mention what you see when you book.
