Meaning
Severity
Common Symptom
DF
Defrost System Fault
Medium
Unlike a compressor or fan failure, a defrost fault causes a slow, progressive warm-up as frost accumulates on the evaporator coil over days and restricts the cold airflow that maintains cabinet temperature. The rise may be barely noticeable at first.

FROST-BUILDUP
Excessive Frost Accumulation (No Electronic Code)
Medium
On Kenmore manual-defrost chest freezers, frost accumulates naturally on interior surfaces from normal door opening and food storage. A buildup exceeding 1/4 inch significantly reduces storage capacity and insulation efficiency, signaling that a scheduled manual defrost is overdue.

HI
High Temperature Alarm
High
The Kenmore Elite upright freezer display alternates between HI and the current temperature reading, and the alarm horn sounds periodically until the condition is acknowledged or the temperature falls back within range.
View
NO-COOLING
Freezer Not Cooling (No Electronic Code)
High
The most unmistakable symptom — food that should be solidly frozen is soft, thawed, or beginning to spoil, and the interior cabinet feels no colder than room temperature even after the unit has been running for several hours.
View
OP
Temperature Sensor Open Circuit
Medium
The Kenmore Elite upright freezer display replaces the normal temperature readout with the OP fault code, indicating the board cannot obtain a valid temperature reading from the cabinet sensor.
View
PF
Power Failure Detected
Low
As soon as utility power returns to the Kenmore Elite upright freezer, the electronic control board displays PF and sounds the alarm tone to alert the user that cooling was interrupted and food temperatures should be assessed.
View
SH
Temperature Sensor Short Circuit
Medium
The Kenmore Elite upright freezer control panel replaces the normal temperature display with SH, indicating the temperature sensor is reading as a dead short and the board cannot use that value for temperature regulation.
