SourceSears PartsDirect: Kenmore 111 bottom-freezer error codes (Wayback copy, Nov 2019)
Kenmore bottom-freezer Trio models whose number starts 111, which have a separate coil for the fresh food side; rD Lo and rD Hi are diagnostic mode codes.
Before you book,
in this order.
Each step comes from Kenmore's own guidance for rD Lo or rD Hi on its refrigerators. Follow it to the end: the last card says whether this is a visit.
Check that the number on the model label begins 111 and the unit is a bottom-freezer.
Note whether the fresh food side has been running warmer than usual in the last few days.
Book a visit and read out rD, so the second coil's sensor is checked rather than the freezer's.
What not to do
rD is not the same as rt. rD is a defrost sensor inside the cabinet, while rt reads the room.
