- Must only be used where the manufacturer specifies this exact part number: 12781.
Installation & Operation Notes:
- Installation should be performed by a qualified HVAC technician.
- Reference the controlled equipment's service/installation manual to confirm the required capacitor ratings and proper terminal connections before energizing the system.
- The provided sources do not include detailed wiring diagrams or safety procedures; follow equipment documentation and standard capacitor handling practices appropriate for HVAC service.
Maintenance & Troubleshooting:
- This capacitor is typically replaced when diagnostics indicate a run capacitor is out of specification or when motor operation issues are traced to the dual run capacitor (diagnostic procedures are not provided in the supplied sources).
- If issues persist after replacement, confirm the installed capacitor matches the required MFD and voltage ratings and that all connections are correct per the equipment documentation.
Certifications & Compliance:
- Manufacturer listing states UL & cUL for these capacitors.
User Reviews & Q&A Summary:
- Review themes commonly describe it as a correct replacement capacitor that restores cooling operation when a failed capacitor is replaced.
