Quick answer
Four flickers of the control board LED mean the control senses the refrigerator door open for more than 1 hour on Kenmore top-freezer refrigerators starting 111.
Model compatibility
Kenmore reuses codes across series and model years, so LED 4 flickers may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What thiscode means
Control senses refrigerator door open for more than 1 hour.
On Kenmore top-freezer refrigerators with model numbers starting 111, four flickers of the main control board LED mean the control senses the refrigerator door open for more than 1 hour.
Counting the flickers
Watch the LED on the main control board: it blinks, rests, and blinks again, and the number of blinks is the code. Reaching it means taking off the board cover. Keep your hands out of the refrigerator during that time, as the board carries electricity while the unit is plugged in. Once you have the count, unplug the refrigerator and refit the cover.
Note
This is a different kind of code from the sensor counts. The manual lists no owner procedure for it, so if four flickers keep returning, a technician should look at the refrigerator.
Related flicker counts
LED 3 flickers is the defrost temperature sensor, and LED 6 flickers is defrost heater failure. For sensor counts see LED 1 flicker for the refrigerator temperature sensor.
Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
