Lg Range HE903PAWAP Parts

This carbon-film resistor is a replacement electrical resistor used on appliance control boards to regulate current in a specific circuit, helping restore correct circuit behavior and stable operation. What it does:

• Limits or controls current flow in a control or power circuit to protect and stabilize surrounding components
• Helps maintain proper function of the control board circuitry
• A failed resistor can cause intermittent operation, loss of specific functions, error codes, or the appliance not to operate as intended
• Small, passive component that typically fails open, shorted, or out of tolerance

• Disconnect power before servicing and discharge any capacitors on the board
• Handle PC boards and components with anti-static precautions to avoid ESD damage
• Soldering or desoldering is typically required; use proper tools and technique
• Verify correct part placement and orientation per the service manual or board markings during installation

A single variable resistor used to adjust control settings on the appliance's control board. Replaces a worn or faulty control resistor to restore adjustable resistance for proper circuit operation. What it does:

• Provides adjustable resistance for control-circuit functions such as timing or speed regulation
• Can correct erratic or non-responsive control behavior caused by an open or degraded resistor
• Helps stabilize voltage/current to downstream components when the resistor is within spec
• Commonly used when adjustments or user controls no longer change the appliance behavior

• One variable resistor (single)

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the resistor and circuit board carefully; avoid bending leads or applying excess force
• Observe electrostatic discharge (ESD) precautions when touching electronic components
