Lg Wall Oven RU23LZ21 Parts

This board-mounted transistor FET assembly replaces failed MOSFETs that control power switching on the appliance's electronic control board. Fits directly on the circuit board to restore reliable switching and electrical performance. What it does:

• Switches power to motors, heaters or other high-current components on the control board
• Replaces burned, shorted or open MOSFET transistors that prevent normal operation
• Can address symptoms such as motors not running, intermittent operation, or related error/fault codes
• Helps stop electrical arcing or overheating when the control board's power stage is compromised

• Disconnect power before servicing the appliance to avoid shock or damage.
• Inspect the control board and surrounding components for heat damage before installing.
• Handle the FETs and board by the edges; avoid static discharge—use proper ESD precautions.

This FET transistor pack replaces the power switching transistors used on the appliance control board to restore reliable power switching. It helps the board control motors and high-current circuits more effectively. What it does:

• Switches high-current power for motors, compressors or heating elements on the control board
• Prevents or corrects intermittent operation or failure to start when FETs have failed
• Can cause error codes, loss of motor function, or no power to specific circuits when defective
• Restores proper on/off switching of high-current loads when installed and functioning

• Disconnect power before servicing; verify power is removed to avoid shock
• This part typically mounts to or on the control board; board removal may be required
• Observe ESD precautions and handle board components carefully
