Description

This replacement transistor restores proper switching and control on compatible appliance control boards, helping the unit run reliably and preventing intermittent failures. Use this transistor to replace a damaged or non-responsive switching component. What it does:

• Acts as a switching element on the appliance control/inverter board to enable motor, compressor, or heater control
• Can stop symptoms such as no-start, intermittent operation, or loss of specific functions when a transistor has failed
• Transfers control signals and helps regulate current flow for associated circuits
• Works as a direct replacement for the failed transistor on the original board

What's included: One replacement transistor Install notes:

• Only install on the matching control board and orientation
• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the transistor and PCB with anti-static precautions when possible
