- Other Compatible Models: Same specification 24V engineering machinery from Sinomach Heavy Industry, Longking, Komatsu, Liugong, etc.
Supplementary Notes
- Common Fault Symptoms: Non-engagement of the air conditioner compressor, non-rotation of the fan, or lack of power to corresponding loads are likely due to contact erosion or coil damage in this relay.
- Replacement Note: The 056800-3060 is compatible with other 24V 5-pin relays in the same DENSO series (e.g., 056800-3050/3070) as they share the same pin definition. However, using the original factory model is recommended to ensure long-term stability.
