Daikin-McQuay 910181935 Capacitor

Daikin Applied 910181935 is a 1.5 MFD 440V motor run capacitor designed for use in commercial HVACR systems to support stable motor operation in condenser fan motors and blower assemblies. It is commonly used in Daikin Applied equipment where consistent phase shift and reliable torque characteristics are required for efficient performance. The 440V rating provides solid electrical tolerance for continuous-duty applications, making it suitable for rooftop units, air handlers, and similar HVAC systems.

This capacitor helps maintain proper motor starting and running performance by stabilizing electrical flow, which supports consistent airflow and overall system efficiency. It is typically used as a replacement part during service repair or preventative maintenance to restore OEM-level operation. Correct microfarad matching is critical to ensure proper motor function and to avoid performance issues.

Key benefits:

• Supports stable condenser fan and blower motor operation
• Maintains consistent HVAC airflow performance
• Designed for 440V commercial HVAC applications
• Compact size for straightforward field replacement
• Helps restore system efficiency during maintenance or repair

Common questions:
Technicians often ask if the microfarad rating must match exactly — it does, and 1.5 MFD should be matched precisely. Another common question is compatibility, so voltage and capacitance should always be verified against the original equipment specifications before installation.
