Technical Specifications:

• Board Type: Main electronic control PCB
• Input Voltage: 220–240 V AC, 50/60 Hz
• Output Channels: Motor drive (triac), water valve solenoid (2), heater relay, drain pump relay, door lock solenoid, temperature sensor (NTC) input
• Microcontroller: 8-bit MCU (specific variant per production batch)
• Connector Type: Multi-pin plug-in connector (typically 16–24 pin)
• PCB Dimensions: Approximately 220 x 180 mm
• Operating Temperature Range: 0°C to 60°C
• IP Rating: IPX0 (internal board — not exposed to water directly, but conformal coated)
• Compliance: CE, RoHS, REACH

Structural Features:

• Double-sided FR-4 PCB with through-hole and SMD components
• Conformal coating (acrylic or silicone) protecting against humidity and condensation
• Key connector blocks: Main power input, motor triac output, valve solenoid outputs, sensor inputs, door lock output, display/user interface connector
• Diagnostic LED indicators on board for service technician troubleshooting
• EMI filter circuit at power input stage

Material Composition:

• PCB Substrate: FR-4 glass-reinforced epoxy laminate (TG130 or TG150)
• Solder: Lead-free SAC305 (Sn96.5/Ag3.0/Cu0.5)
• Coating: Acrylic conformal coating (UV-curable)
• Connectors: Molex or JST brand locking connectors
• Components: Triac (BTA16 or equivalent), relays (Omron or equivalent), NTC thermistor, capacitors (electrolytic + film), resistors, diodes, optocouplers

Working Principle:
The microcontroller executes the selected wash/dry program by sending timed signals to output drivers. The triac controls motor speed via phase-angle firing. Relays switch the water inlet valves (hot/cold), drain pump, and heater element. The NTC thermistor provides real-time water temperature feedback for closed-loop heating control. The door lock solenoid is energized during wash cycles to prevent door opening. All operations are sequenced according to the program stored in the MCU firmware.

Key Advantages:

• Genuine AEG OEM part — exact pinout, firmware, and component match
• Conformal coated — resistant to the high-humidity environment inside washing machines
• Diagnostic LEDs — enables rapid fault identification during service
• RoHS compliant — lead-free solder, no restricted substances

Applicable Industries / Use Cases:

• AEG washing machine repair and maintenance
• AEG dryer-washer servicing
• Appliance repair technician parts supply

Installation Requirements:

• Disconnect mains power and drain residual water before any work
• Disconnect all wiring harnesses from the old board (photograph connections before disconnecting)
• Mount the new PC-0984-485 board in the exact same screw hole positions
• Reconnect all harnesses to matching connectors — do not force mismatched plugs
• Verify all connections, then perform a test run with no load (empty drum)

Usage Notes:

• Handle by edges only — do not touch component side (ESD risk)
• Store in anti-static bag when not installing immediately
• If the new board fails immediately, check for wiring faults or short circuits in the appliance before condemning the board
• Firmware on this board is not user-upgradable — it is programmed at the factory for the specific appliance model
