Error codeLED 3 flickers
ApplianceRefrigerator
Count three blinks from the LED on the main control board, then a pause, and the verdict is a failed defrost temperature sensor. The code applies to top-freezer Kenmore refrigerators with 111-prefix model numbers.
Job of the sensor
Evaporator temperature is what the manual says it keeps track of.
Checks, in order
Unplug the unit.
Follow the wires from the sensor to the board and mend any break.
From the board, a technician reads resistance through the defrost sensor circuit.
Reading beyond the manual’s range? New sensor.
Listed part: the defrost temperature sensor.
Counting safely
The cover over the board must come off to expose the LED. Because the board is live whenever the plug is in, keep out of the interior and refit the cover when finished.
Three blinks and a Kenmore top-freezer in San Francisco or the Bay Area? Start at Kenmore refrigerator repair or call (415) 825-6393, giving the model number and the count you saw.
Model compatibility: Kenmore reuses codes across series and model years, so LED 3 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 this code means
Three LED flickers signal a defrost temperature sensor failure.
Important safety warning. 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.
