This Memory IC is a board-mounted integrated circuit that stores control settings and diagnostic data for the appliance's main control board, helping the unit retain programming and error history. What it does

• Stores configuration, calibration, and diagnostic codes used by the control board
• Helps the appliance retain user settings after power interruptions
• Can prevent recurring faults caused by corrupted memory data
• Associated with error codes, display issues, or loss of saved settings

• One Memory IC

• Board-level component: soldering skills and tools required
• Disconnect power and follow ESD (electrostatic discharge) precautions before handling
• Verify board compatibility and orientation before soldering

This fixed cement resistor is a durable through-hole resistor used in appliance control circuits to limit current and stabilize voltage, helping electronics run safely and reliably. What it does:

• Provides a fixed resistance value in control and power circuits to limit current flow
• Helps protect sensitive components from current spikes and contributes to stable operation
• A failed or burned resistor can cause loss of function, intermittent operation, or blown fuses
• Commonly mounted on control boards or chassis where higher power dissipation is required

• One fixed cement resistor as shown

• Disconnect power and unplug the appliance before attempting service
• Discharge capacitors and wait for components to cool before handling the board
• Replace with the exact resistance and wattage specification; do not substitute without verification

This is a replacement KRA103M transistor used on appliance control electronics to regulate and switch electrical signals. Replacing a faulty transistor can restore reliable operation of electronic circuits and controlled components. What it does:

• Switches and regulates current on the control board to allow proper function of electronic circuits
• Helps control power to components that rely on the board's signals
• Corrects symptoms such as intermittent control response, components not powering, or erratic electronic behavior
• Small electronic replacement; requires proper handling and mounting to ensure reliable contact

• Disconnect power to the appliance before servicing to avoid shock or damage
• Use ESD-safe handling to protect the transistor and the circuit board
• Installation typically requires soldering; inspect surrounding components and board pads for heat damage when replacing
