Bin Presence Switch / Door Switch Fault

E12

EdgeStar ice maker shows E12; unit may not respond to button presses or may behave erratically.

User Interface / Keypad Communication Fault

E13

EdgeStar ice maker displays E13; unit may not defrost properly and ice may stick to the evaporator.

Defrost / Hot Gas Valve Fault (for models using hot gas harvest)

E14

EdgeStar ice maker shows E14; unit may overfill the bin with ice or fail to stop ice production when full.

Ice Level Sensor Stuck / Calibration Fault

E15

EdgeStar ice maker displays E15; unit may not start a cycle and may indicate a door or panel is open.

Door Switch / Safety Interlock Fault

E16

EdgeStar ice maker shows E16; unit may run but produce very small or hollow ice cubes.

Evaporator Temperature / Freeze Time Control Fault

E17

EdgeStar ice maker displays E17; unit may not circulate water over the evaporator plate.

Circulation Pump Fault

E18

EdgeStar ice maker shows E18; unit may leak water internally or shut down due to a leak sensor trigger (on models equipped).

Internal Leak / Overflow Sensor Fault

E19

EdgeStar ice maker displays E19; unit may not recognize the selected ice size or may default to one size only.

Ice Size Selector / Potentiometer Fault

E2

EdgeStar ice maker stops mid-cycle and displays E2; unit may beep and not resume ice production.

Ice Bin Full Sensor / Infrared Sensor Fault

E20

EdgeStar ice maker shows E20; unit may not start due to low or high line voltage detection (on models with voltage monitoring).

Line Voltage Out of Range Fault

E3

EdgeStar ice maker displays E3 and stops making ice; compressor may not start or may shut off quickly.

Evaporator Temperature Sensor (Thermistor) Fault

E4

EdgeStar ice maker shows E4; unit may run briefly then shut down, or may not start the ice-making cycle at all.

Water Inlet Valve / Water Supply Fault

E5

EdgeStar ice maker displays E5 and stops; ice production is halted and unit may beep repeatedly.

High Temperature / Overheat Protection Fault

E6

EdgeStar ice maker shows E6; unit may fill with water but not freeze properly, or may shut down early in the cycle.

Compressor / Refrigeration System Fault

E7

EdgeStar ice maker displays E7; unit may stop mid-harvest or fail to release ice from the evaporator plate.

Harvest Motor / Ice Sweep Motor Fault

E8

EdgeStar ice maker shows E8; water may overflow the evaporator tray or the unit may not detect water level correctly.

Water Level Sensor / Float Switch Fault

E9

EdgeStar ice maker displays E9; unit may shut down and not restart until power is cycled.

High-Pressure Switch / Refrigeration Protection Fault

Symptom

EdgeStar ice maker bin is warm and ice melts quickly after production.

Bin Not Cooling – Insulation or Air Leak

Symptom

EdgeStar ice maker cycles on and off frequently without completing a full ice-making cycle.

Short Cycling – Overheat or Sensor Misread

Symptom

EdgeStar ice maker door or bin lid is difficult to close or pops open during operation.

Door / Bin Alignment or Hinge Problem

Symptom

EdgeStar ice maker emits a burning smell or shows signs of overheating around the compressor area.

Overheating / Electrical Component Failure

Symptom

EdgeStar ice maker forms ice on the evaporator but does not release it into the bin.

Harvest Failure – Ice Stuck to Evaporator

Symptom

EdgeStar ice maker ice cubes are fused together in large clumps in the bin.

Ice Clumping – Bin Temperature or Harvest Issue

Symptom

EdgeStar ice maker interior surfaces and evaporator are heavily scaled with white mineral deposits.

Heavy Scale Buildup – Poor Maintenance / Hard Water

Symptom

EdgeStar ice maker is very noisy during operation; rattling, buzzing, or grinding sounds are heard.

Excessive Noise – Mechanical or Fan/Pump Issue

Symptom

EdgeStar ice maker leaks water inside the cabinet; ice bin may be wet and water may pool in the bottom.

Internal Leak – Overflow or Misaligned Drain

Symptom

EdgeStar ice maker leaks water onto the floor from underneath the unit.

External Water Leak – Drain or Inlet Line Failure

Symptom

EdgeStar ice maker lights up but buttons do not respond; unit stuck in one mode.

Unresponsive Controls – Keypad or Control Lock

Symptom

EdgeStar ice maker makes ice very slowly; bin never fills and ice cycles take much longer than normal.

Slow Ice Production – Marginal Cooling or Airflow Problem

Symptom

EdgeStar ice maker overflows the ice bin; ice spills out of the door or grille.

Overproduction – Ice Level Detection Failure

Symptom

EdgeStar ice maker produces cloudy or white ice instead of clear cubes (on clear-ice models).

Cloudy Ice – Water Quality or Freeze Pattern Issue

Symptom

EdgeStar ice maker produces ice that is wet or slushy instead of solid cubes.

Incomplete Freezing – Short Freeze Cycle or Warm Evaporator

Symptom

EdgeStar ice maker produces ice with a bad taste or odor.

Contaminated Water Path / Biofilm or Scale Buildup

Symptom

EdgeStar ice maker runs but makes no ice at all; fan and compressor may run, but bin remains empty.

No Ice Production – Refrigeration or Water Supply Failure

Symptom

EdgeStar ice maker runs but produces very small, thin, or hollow ice cubes.

Undersized or Hollow Ice – Water Flow or Freeze Time Issue

Symptom

EdgeStar ice maker stops making ice but the bin is not full; unit appears idle.

Premature Shutoff – False Full-Bin Detection

Symptom

EdgeStar ice maker vibrates excessively or rattles against cabinetry when running.

Vibration / Installation Issue

Symptom
