This error code appears when there are ice maker issues and it is not related to the freezer fan. However, the error may block the functioning of an entire system. If you see 14E on the display, it is advisable to reset the fridge. Unplug your fridge for about 20 minutes and ground it. Then plug it again to restore power and launch the diagnostic mode. When it is over, exit it. Most units regain operability after this simple procedure and display correct parameters. While running the diagnostic mode, please, make sure all temperature indicators are correct. The mode can store various error codes, so check it for other codes, which may cause (or have caused) various issues.
Ice Cuber’s Main Units
1. Drain hose
It uses almost the same type of hose as ones that are used in washing machines, except it is much more likely to clog.
Causes of clogs:
- Using the ice cube generator for cooling drinks and food.
- The ice cube generator is installed below the recommended drain level.
- The hose’s length (no bends, curves or winding) should match the distance between the ice cube generator and sewer pipe.
- If you have moved the device during a clean-up or home improvement, please, check the hose.
2. Programmer (12 min)
This is one of the main units, as it regulates the freeze cycle and defrost process. The evaporator thermostat directs current to the programmer’s micro motor, which launches defrosting 12 minutes later.
This unit is also referred to as ‘defrost timer’. The timing is carried out thanks to a gear, which rotates with the micro motor.
Diagnostic: Turn the programmer’s stem to ‘defrost’ position using a screwdriver. If the unit is functional, the defrost cycle will start in several minutes.
3. Evaporator thermostat K50 L3163
Once temperature reaches a set level, the thermostat directs current to the programmer’s micro-motor.
Diagnostic: To check it, press on the spring opposite the contact set, with a screwdriver. Use a multimeter.
4. Thermostat for container K50 L1074
A thermostat is installed in the container to control and prevent ice buildup. At a set temperature, it disconnects the ice cube generator from mains.
Diagnostic: See the Evaporator Thermostat section.
5. Coilless solenoid valve
It blocks direct transfer of heated gas from the condenser to the evaporator during the freezing process. Freon enters the evaporator via a capillary tube. In the defrost mode, the valve opens and lets hot gas into the evaporator.
- Direct current to the valve’s coil (defrost).
- Remove and then put it back in. It should produce a specific sound. Also, check pressure indication using a low- and high pressure manometer.
6. Solenoid valve with a coil
Diagnostics: Use a multimeter when testing it.
Create pressure in the water system and directs it toward the spray header.
8. Pressostat (in models featuring water-cooled condensers)
Regulates condensation temperature by directing current toward the water valve.
9. Double solenoid water valve
A double water valve is used in ice cube generators featuring water-cooled condensers. One part is for the condenser, and the other one – for the evaporator tray. It is very similar to a washing machine part. The difference is that it features a water reducer.
Water flow stabilizers are marked in colors according to throughput capability. For example, orange denotes 2.5 L/min, white – 1.6 L/min.
- When current is directed to the coil, the valve should open.
- Check the coil using a multimeter.
10. Single solenoid water valve
For ice cube generators featuring air-cooled condensers.
Diagnostics: It is diagnosed in the same way as a double valve. Please, always clean the removable coarse filter on the ¾ side.
11. Condenser micro-motor
A universal micro-motor, for example – Elco 10/20, 230В, 0,20A; output capacity – 5Wt, 1300 rpm. This motor is used in a variety of refrigerator models. Capacity depends on the ice cube generator model.
- If you hear screeching or any other unusual sound, replace it.
- Do not lubricate, repair, or modify it in any other way.
12. Fan blades
This part is extremely delicate and complex. Please, always clean the blades and check the balance when carrying out any maintenance work on the ice cube generator.
13. Air-cooled condenser
Please, blow it with compressed air regularly. When necessary, rinse it with a special kind or cleanser.
Diagnostic: Coolant leaks often occur in condensers. A leak can be detected by oily spots near the damaged area. In condensers with copper tubing, the damage can be fixed with a torch and phosphorus copper paste solder.
14. Sealed compressor
Cube ice generators use medium temperature sealed compressors, because in the defrost mode they work in the +25°С temperature mode.
R-134a and R-404a are the most common coolant types. Manufacturers: ACC, Aspera, Tecumseh Europe L’Unite Hermetique.
Bar type ice cube makers with capacity ranging from 18 kg/day to 25 kg/day feature a 430W compressor with a boiling temperature of +15 °С.
15. Emergency pressostat
This unit is installed in the liquid cooling loop to prevent the compressor from overheating. Mostly, it stops the cube ice generator when the condenser becomes dirty.
Diagnostics: When the unit is up and running, all contacts are closed properly.
16. Nozzle water header
Lime buildup often blocks the nozzles. Please, use a water softener.
Diagnostic: Make sure water jets from the nozzles onto the evaporator in parallel streams.
Freon will boil in the evaporator at – 20 °С.
18. Capillary tube
Any refrigerator unit, including an ice cube generator, features an expansion device. In this case, it is the capillary tube. A clogged capillary tube is one of the most common causes of ice generator failures.
Diagnostics: Low pressure in the suction line is a clear sign of a clog in the capillary tube.
19. Copper filter dryer
Installed before the capillary tube, it prevents clogs and dries the cooling loop.
- A clogged filter drier’s surface is covered with snow.
