What d on the Refrigerator Display (106-prefix) Means
A lower-case d in the refrigerator display of a 106-prefix Kenmore means the air damper has stuck. That damper is the flap controlling how much cold air passes from the freezer into the fresh-food compartment, so a stuck one leaves one side too warm or the other too cold.
Common Causes of d on the Refrigerator Display (106-prefix)
- A package jammed in the damper opening
- A damper flap broken or seized in position
- Ice built up around the damper mechanism
🔧 One Safe Check You Can Try
Take a look at the vent between the two compartments for a package wedged into it; food pressed against the damper is a common and entirely visible cause.
⚠ Why You Shouldn't Go Further Than That
- Unplug the refrigerator before the damper housing is opened; its motor wiring returns to a live control board.
- Forcing a frozen damper flap by hand snaps the plastic and turns an ice problem into a parts order.
- A damper fitted while ice keeps forming around it seizes again within weeks.
