2. Коопсуздук маалыматы

• Кандайдыр бир орнотууга, тейлөөгө же оңдоого аракет кылуудан мурда муздаткычты дайыма электр кубатынан ажыратыңыз. Антпесе электр шок же олуттуу жаракат алып келиши мүмкүн.
• If you are not confident in performing the installation, seek assistance from a qualified technician.
• Кыска туташуулардын алдын алуу үчүн бардык электр байланыштары коопсуз жана туура изоляцияланганын текшериңиз.
• Handle the capillary tube (probe) with care. Do not bend it sharply or kink it, as this can damage the sensor and affect performance.
• Verify that the replacement controller matches the specifications and dimensions of the original part to ensure compatibility and proper function.

The WDF26C-EX (and similar WDF26/WPF26 models) is a mechanical temperature controller commonly used in refrigerators. It consists of a main control unit with electrical terminals, a temperature adjustment shaft, and a capillary tube (probe) that senses the internal temperature of the appliance. When the temperature changes, the fluid inside the capillary tube expands or contracts, activating a switch within the control unit to turn the compressor on or off, thereby maintaining the desired temperature.

5. Орнотуу

Replacing a refrigerator temperature controller requires careful attention to safety and detail. Follow these general steps:

1. Кубатты өчүрүү: Unplug the refrigerator from the wall outlet to completely cut off power.
2. Access the Old Controller: Locate the existing temperature controller. This is typically found inside the refrigerator compartment, often near the light assembly or at the top of the fresh food section. You may need to remove plastic covers or panels.
3. Документ байланыштары: Before disconnecting anything, take clear photos of the wiring connections to the old controller. Note which wire connects to which terminal.
4. Эски контроллерди алып салуу: Carefully disconnect the wires and unmount the old controller. Pay attention to how the capillary tube is routed and secured within the refrigerator.
5. Install New Controller:
   • Mount the new WDF26C-EX controller in the same location as the old one, ensuring the mounting hole distance (5.5mm) aligns.
   • Connect the electrical wires to the new controller's two terminals, matching the connections you documented earlier.
   • Route the new capillary tube (probe) exactly as the old one was routed. The probe tip (52.5mm) and overall length (55cm) are critical for accurate temperature sensing. Ensure the probe tip is positioned correctly within the refrigerator compartment, usually clipped to the evaporator coil or a specific sensing area. Avoid kinking or damaging the tube.
6. Кайра чогултуу: Алынып калган капкактарды же панелдерди алмаштырыңыз.
7. Күчтү калыбына келтирүү: Муздаткычты кайра розеткага сайыңыз.
8. Сыноо операциясы: Set the temperature control to a mid-range setting and monitor the refrigerator's temperature over several hours to ensure it is cooling correctly.

Маанилүү: The functionality of the temperature controller relies on the capillary tube accurately sensing the temperature. Improper routing or damage to the tube will lead to incorrect temperature regulation.

6. Операция

Once installed, the temperature controller operates automatically to maintain the set temperature. The control knob (connected to the adjustment shaft) allows you to select the desired cooling level. Turning the knob typically adjusts the cut-in and cut-out temperatures of the compressor cycle.

• Температураны жөндөө: Rotate the control knob to increase or decrease the cooling intensity. Higher numbers or colder settings typically mean the compressor will run more frequently or for longer durations, resulting in a colder internal temperature.
• Баштапкы орнотуу: After installation, allow the refrigerator several hours to stabilize its temperature before making fine adjustments.
• Мониторинг: Use a refrigerator thermometer to verify that the internal temperature is within the safe range for food storage (typically 35-38°F or 1.7-3.3°C for the fresh food compartment).

7. Техникалык тейлөө

The WDF26C-EX temperature controller is a sealed unit and generally requires no internal maintenance. However, periodic checks can help ensure its longevity and proper function:

• Визуалдык текшерүү: Periodically inspect the controller and its wiring for any signs of damage, corrosion, or loose connections.
• Capillary Tube: Ensure the capillary tube remains securely in its sensing location and is not damaged or kinked.
• Тазалык: Keep the area around the controller clean and free from dust or debris, which could potentially interfere with its operation or lead to overheating of electrical components.

9. Колдонуучунун кеңештери

• When replacing, ensure the new controller's probe length and terminal configuration match your old one for seamless compatibility.
• Take photos of the original wiring before disconnecting to simplify reassembly.
• After installation, give the refrigerator at least 12-24 hours to reach a stable temperature before making fine adjustments.
