The Amana-Goodman D4976682 Compressor Overload is a critical safety component designed for precise thermal protection in residential and light commercial condensing units. This OEM replacement part (superseding part number D49766-82) monitors compressor motor amperage and internal temperature, breaking the electrical circuit to prevent winding failure during locked rotor conditions or excessive thermal loads. Engineered for Amana and Goodman HVAC systems, it ensures proper current sensing and reliable cycling under high-stress operation. For field technicians, utilizing this exact HVAC replacement part is essential for maintaining the factory-specified overload trip curve, preventing premature compressor burnout and ensuring consistent system performance. This component integrates seamlessly into existing wiring harnesses, providing the necessary electrical protection to safeguard the heart of the refrigeration cycle during voltage fluctuations or refrigerant flow issues. Key Benefits: Matches OEM specifications for exact Amana and Goodman equipment compatibility. Provides thermal overload protection to prevent catastrophic compressor motor failure. Features a precise current-sensitive design to prevent nuisance tripping while maintaining safety. Simplifies repairs by replacing superseded legacy part number D49766-82. Ensures durable electrical conductivity and reliable performance in high-ambient environments. Common Questions: How do I verify if the D4976682 is the correct overload for my unit? Cross-reference the compressor model number and the existing overload part number on the wiring diagram. This part is the direct replacement for the D49766-82 series used in several Goodman-manufactured chassis. What causes a compressor overload to trip repeatedly? Frequent tripping usually indicates high amperage draw, a failing start capacitor, low voltage supply, or a potential mechanical bind within the compressor itself. Can I bypass this overload for testing purposes? While a technician might momentarily bypass for diagnostics, the overload protector must be installed during operation to prevent permanent damage to the compressor windings.
