Quick answer
One flicker of the main control board LED means a refrigerator temperature sensor failure on Kenmore top-freezer refrigerators with model numbers starting 111.
Model compatibility
Kenmore reuses codes across series and model years, so LED 1 flicker 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
Refrigerator temperature sensor failure.
Kenmore top-freezer refrigerators with model numbers starting 111 report errors through an LED on the main control board. The LED flickers a number of times, then pauses, and the count is the code. One flicker is a refrigerator temperature sensor failure.
How to count the flickers safely
Remove the main control board cover to see the LED. Do not touch anything inside the refrigerator while the cover is off, because the board is connected to electricity whenever the refrigerator is plugged in. Unplug the refrigerator to disconnect power and put the cover back after you have counted.
About this sensor
The manual says the refrigerator temperature sensor attaches to the back wall inside the refrigerator compartment. With the refrigerator unplugged, its wiring to the control board is checked for damage and any broken wires are repaired. A technician then measures the resistance through the sensor circuit and replaces the sensor if the reading is outside the manual’s range.
Other flicker counts
Two flickers is LED 2 flickers for the ambient temperature sensor, and three is LED 3 flickers for the defrost temperature sensor. A freezer sensor shows as OP (freezer display) when the freezer temperature sensor is open.
