Defrost Drain / Sensor Fault
Symptom
Buttons on the freezer control panel do not respond or respond intermittently.
Unresponsive Controls – UI Keypad Failure
Symptom
Door alarm sounds even though the door appears closed; alarm may stop if door is pressed firmly.
False Door Open Alarm
Symptom
Excessive frost buildup on interior walls, baskets, and food; frost especially heavy near the door.
Excessive Frost – Air Infiltration
Symptom
Freezer cools but makes a loud humming or buzzing noise from the compressor area.
Excessive Compressor Noise
Symptom
Freezer display is blank or unreadable, but the unit still cools.
Display Failure – UI Board or Backlight
Symptom
Freezer door is difficult to open again immediately after closing; a vacuum seems to hold it shut.
Door Vacuum / Pressure Equalization Issue
Symptom
Freezer emits a high-pitched squealing or chirping noise from inside the cabinet.
Evaporator Fan Bearing Failure
Symptom
Freezer exterior sides or door feel very hot to the touch.
Cabinet Overheating – Condenser or Mullion Heater Issue
Symptom
Freezer has a strong musty or sour odor inside, even after removing spoiled food.
Persistent Odor / Contamination
Symptom
Freezer interior light does not work, but cooling is normal.
Interior Light Failure
Symptom
Freezer interior light works but compressor never starts; faint clicking may be heard periodically.
Compressor Will Not Start – Start Device or Compressor Failure
Symptom
Freezer interior temperature fluctuates widely; some days food is very hard, other days slightly soft.
Temperature Fluctuation – Control or Sensor Instability
Symptom
Freezer is leaking water onto the floor from the front or underneath.
External Water Leak – Defrost Drain or Door Gasket Issue
Symptom
Freezer is too cold; items near the back are rock-hard or frosted; temperature does not respond to control changes.
Overcooling – Thermostat or Sensor Out of Calibration
Symptom
Freezer makes a gurgling or hissing sound periodically; cooling seems normal.
Normal Refrigerant Flow Noise (Perceived Fault)
Symptom
Freezer makes a loud rattling or vibrating noise, especially when the compressor is running.
Cabinet Vibration / Mechanical Rattle
Symptom
Freezer not cooling at all; interior is warm; compressor and fans are not running; display may be lit.
No Cooling – Control or Power Circuit Failure
Symptom
Freezer not starting at all; display is off; no lights or sounds.
No Power – Supply or Internal Fuse Failure
Symptom
Freezer runs but does not reach set temperature; food is soft; compressor and fan seem to run continuously.
Poor Cooling – Sealed System or Airflow Problem
Symptom
Freezer runs constantly and never seems to shut off, though temperature is acceptable.
Continuous Run – Control Logic or Sensor Issue
Symptom
Freezer trips the household circuit breaker or GFCI outlet when it starts.
Electrical Short or Ground Fault
Symptom
Thick sheet of ice forms on the freezer floor under the bottom basket.
Ice on Floor – Blocked Defrost Drain
