The part number **0011260060** is a specific electronic component primarily associated with **Haier** and **Fisher & Paykel** appliances. It is a **Power Module** (or Power PCB) used in washing machines and washer-dryer combos. --- ### 1. Component Overview The power module acts as the "brain" of the appliance's electrical system. Unlike the display board (user interface), this board handles high-voltage distribution and executes the physical commands of the wash cycle. ### 2. Technical Specifications | Feature | Description | | :--- | :--- | | **Part Type** | Main Power Control Board (PCB) | | **Manufacturer** | Haier / Fisher & Paykel | | **Voltage** | Typically 220V - 240V (Region dependent) | | **Application** | Front Load Washing Machines / Washer-Dryers | | **Key Functions** | Motor control, heating element activation, pump operation | --- ### 3. Key Electronic Functions This board contains several critical sub-circuits that manage the machine's hardware: * **AC to DC Rectification:** Converts incoming wall power into stable low-voltage DC (typically 5V or 12V) to power the onboard microprocessors and sensors. * **Motor Inverter Circuit:** Many units using this board feature brushless motors. The board uses **IGBTs** (Insulated-Gate Bipolar Transistors) to control the speed and direction of the drum. * **Relay Switching:** High-current relays are present to turn the water heater and the drain pump on and off. * **Sensor Interfacing:** The board processes signals from the NTC (temperature sensor), pressure switch (water level), and door lock assembly. ### 4. Common Failure Symptoms If this electronic part fails, the appliance may exhibit the following issues: 1. **No Power:** The machine does not turn on despite being plugged in. 2. **Error Codes:** Specific codes (e.g., Haier "E1" or motor-related errors) often point to a communication failure with this board. 3. **Incomplete Cycles:** The machine stops mid-cycle, fails to drain, or refuses to spin. 4. **Short Circuits:** Tripping the household circuit breaker when the machine starts. --- ### 5. Maintenance and Safety > **Warning:** Electronic power modules store high-voltage electricity in capacitors even after the unit is unplugged. * **Static Protection:** When handling this part, use an ESD (Electrostatic Discharge) wrist strap to avoid damaging the CMOS components. * **Visual Inspection:** Look for "cold solder joints," charred components, or leaking electrolytic capacitors if attempting a repair.
