This inverter motor control board manages variable motor speed to enable smooth, efficient operation of the appliance. Replaces a failed inverter to restore proper motor control and reduce erratic motor behavior. What it does:

• Controls variable-speed motor operation and converts power for the motor drive
• Helps maintain steady motor speed during cycles for consistent performance
• Often replaces a faulty inverter causing motor stalls, error codes, or loss of drive
• Can resolve intermittent operation, humming, or motors that won't start

• Disconnect power before attempting replacement to avoid shock or damage
• Handle the control board by its edges and avoid touching components or connectors
• Verify connector alignment and secure mounting; confirm all wiring matches original
• If you see corrosion or other damaged wiring, inspect and repair harnesses before powering up

This replacement fan motor circulates air inside the appliance to maintain proper airflow and temperature. Use it to restore normal cooling and ventilation when the original motor fails or runs intermittently. What it does:

• Drives the appliance fan blade to move air for cooling, defrosting, or venting
• Commonly replaces motors that hum, run slowly, or won't start
• Helps stop uneven temperatures, inadequate cooling, or frost buildup caused by poor airflow
• May reduce abnormal vibration or noise when the motor has worn bearings

• Disconnect power to the appliance before starting any repair
• Handle the motor and wiring carefully; match connectors exactly to avoid damage
• This part may require removing panels, brackets, or the fan blade for access—keep fasteners organized
