AL
Freezer displays AL or flashes an alarm icon with beeping; the temperature may be out of range.
General Alarm Condition (Temperature or Door)
dE
Freezer displays dE or a door icon; the door alarm sounds and cooling may pause.
Door Open Detection Fault
E1
Freezer displays E1 and may not maintain the set temperature; an alarm may sound intermittently.
Cabinet Temperature Sensor Failure
E10
Freezer displays E10; the unit may not start cooling or may shut down shortly after starting.
Compressor Start / Inverter Communication Fault
E2
Freezer displays E2 and may run continuously or cycle erratically; the temperature may be inaccurate.
Freezer Compartment Temperature Sensor Failure
E3
Freezer displays E3; defrost cycles may not occur properly, leading to frost buildup on the evaporator.
Defrost Sensor / Evaporator Thermistor Failure
E4
Freezer displays E4; the unit may not defrost properly or may over-defrost, causing temperature swings.
Defrost Heater or Defrost Circuit Fault
E5
Freezer displays E5; ice production (if equipped with an ice maker) may stop or be inconsistent.
Ice Maker Thermistor / Ice Compartment Sensor Fault
E6
Freezer displays E6; communication between the user interface and main control may be lost; controls may be unresponsive.
Communication Error Between UI Board and Main Control Board
E7
Freezer displays E7; the condenser fan may not run, or the unit may overheat and shut down.
Condenser Fan Motor or Feedback Fault
E8
Freezer displays E8; the evaporator fan may not run, causing warm temperatures and poor airflow.
Evaporator Fan Motor or Feedback Fault
E9
Freezer displays E9; the door alarm may sound even when the door is closed, or interior lights may behave erratically.
Door Switch / Door Sensor Fault
F1
Freezer displays F1; an internal fault is indicated, often related to control board memory or sensor processing.
Main Control Board Internal Error
H1
Freezer displays H1 or a high temperature alarm; the interior is warmer than the setpoint.
High Temperature Condition / Prolonged Warm Event
L1
Freezer displays L1 or a low temperature alarm; the interior may be much colder than the setpoint, sometimes causing excessive frost.
Low Temperature Condition / Overcooling
Symptom
Condensation or moisture forming on the exterior cabinet or around the door gasket.
Cabinet Sweating / Mullion Heater Issue
Symptom
Display shows dashes or blank segments instead of the temperature, but the freezer may still cool.
Display / Sensor Data Error
Symptom
Excessive frost buildup on the back wall or on food items; the freezer appears very icy.
Air Infiltration / Defrost System Issue
Symptom
Freezer control panel buttons are unresponsive or erratic, but the unit still cools.
User Interface Keypad Failure
Symptom
Freezer cycles on and off rapidly or appears to short-cycle.
Control or Sensor Cycling Issue
Symptom
Freezer door difficult to open immediately after closing; it feels like a vacuum.
Normal Pressure Equalization / Gasket Adhesion
Symptom
Freezer door not closing or popping open by itself.
Door Alignment / Gasket Interference
Symptom
Freezer has a chemical, plastic, or burning smell during operation.
Overheating Component or New Appliance Odor
Symptom
Freezer has a strong musty or sour odor.
Odor Contamination / Biological Growth
Symptom
Freezer making a high-pitched squealing or chirping noise intermittently.
Fan Motor Bearing Wear
Symptom
Freezer making a loud humming or buzzing noise from the rear area.
Noisy Compressor or Condenser Fan
Symptom
Freezer making a loud rattling or knocking noise from inside the cabinet, especially when the fan runs.
Evaporator Fan Noise / Ice Interference
Symptom
Freezer not cooling at all; the interior is room temperature, lights may work, but there is no cold air.
Compressor Not Running / No Cooling
Symptom
Freezer runs constantly but does not reach the set temperature; the back wall may show only a partial frost pattern.
Sealed System Undercharge or Restriction
Symptom
Freezer vibrating excessively or making a low rumbling noise that resonates through the floor or cabinets.
Cabinet Vibration / Leveling Issue
Symptom
Ice cubes are small, hollow, or clumped together.
Poor Ice Quality / Low Water Fill
Symptom
Ice maker not making ice in a Monogram freezer with a built-in ice maker.
Ice Production Failure
Symptom
The freezer interior light is not working, but the unit cools normally.
Interior Light Circuit Failure
Symptom
The freezer is not running at all; there are no lights, no display, and it is completely dead.
No Power / Electrical Supply Failure
Symptom
The freezer is too cold; items near the vents are freezing solid or showing freezer burn quickly.
Overcooling / Thermostat or Sensor Miscontrol
Symptom
The freezer is too warm; the temperature fluctuates, and food is soft or thawing.
Insufficient Cooling / Airflow Problem
Symptom
Thick sheet of ice forming on the freezer floor.
Frozen or Misaligned Defrost Drain
Symptom
Water leaking from the bottom front of the freezer onto the floor.
Defrost Drain Clogged or Misrouted
Symptom
Water pooling inside the freezer at the bottom or under baskets.
Internal Defrost Water Overflow
