Frequency conversion drive board for compressors compatible with VNX1116Y and VNB1113Y Key benefits Restores frequency conversion control for compatible compressors, enabling variable speed operation and smoother motor starts. Reduces mechanical stress during startup and shutdown by providing controlled acceleration and deceleration. Helps maintain more stable compressor operation, which can improve system responsiveness and reduce nuisance trips. Designed for direct replacement use with the listed compressor models, simplifying or maintenance tasks. What this part does Acts as the frequency conversion drive board for refrigerator compressors, providing the electronic control needed to vary motor frequency and speed. Controls power delivery and timing to the compressor motor to achieve stepless speed changes and stable running conditions. Compatibility Specifically compatible with compressor models VNX1116Y and VNB1113Y. Intended as a replacement drive board accessory for refrigerators and refrigeration equipment using those compressors. Important attributes Function: Frequency conversion drive board for compressor speed control and motor drive. Form factor: Compact PCB drive board designed to match the mounting and electrical connections of the original unit for straightforward replacement. Construction: Built as an electrical control module suitable for installation in refrigeration systems; uses standard electronic components and connectors common to compressor drive boards. Performance: Provides stable frequency conversion control to enable smoother starts, regulated motor speed, and consistent operation of compatible compressors. Installation and use Intended for technicians or experienced service personnel familiar with refrigeration electrical systems. Install as a direct replacement for the original drive board on compressors VNX1116Y or VNB1113Y following standard safety practices and power isolation procedures. Practical applications and scenarios Household refrigerator : a failed drive board on a home refrigerator compressor that uses model VNX1116Y to restore variable frequency operation and recover normal cooling performance. Commercial refrigeration maintenance: Service technicians replacing a damaged drive board in display case or walkin cooler compressors using VNB1113Y to equipment to steady operation. Equipment refurbishment or parts stocking: Keep on hand as a spare drive board for workshop inventory when servicing refrigeration units with the compatible compressor models. Notes Verify compressor model number before ordering to ensure compatibility. Installation should be performed with power disconnected and by qualified personnel.
