Daikin-McQuay 067782202 Motor

The Daikin-McQuay 067782202 is a professional-grade 1/8HP replacement motor designed specifically for demanding HVACR applications, including PTAC units and water source heat pumps (WSHP). Engineered for multi-speed versatility, this PSC motor operates across a broad 700-1400 RPM range, allowing for precise airflow adjustment in both commercial and industrial environments. This single-phase component is built to handle 208-230V input at 60Hz, ensuring stable performance in systems requiring a 4-speed configuration.

For a successful field installation, technicians should note that this unit typically requires a 4 MFD run capacitor (specifically part #669241501) for optimal torque and efficiency; the capacitor is sold separately. The Daikin-McQuay 067782202 motor features a compact frame size and durable internal bearings designed to mitigate common failure points like shaft binding and thermal overload. When replacing an existing blower motor, verify lead color coding (typically White for Common, Orange for Low, and Black for High) and check for proper 208-230V HVAC motor alignment to prevent premature wear on the blower wheel or housing.

• Multi-Speed Flexibility: Supports 4-speed operations between 700 and 1400 RPM for tailored system balance.
• OEM Compatibility: Direct-fit replacement for Daikin and McQuay climate control systems, ensuring standard electrical and mechanical interfaces.
• Industrial Durability: Constructed with materials resistant to common HVAC stressors, ensuring high-duty cycle performance in high-occupancy buildings.
• Efficient Power Draw: Designed to maintain a low amperage footprint (nominally ~0.82 Amps) during continuous operation.

What are the symptoms of a failing blower motor in a McQuay unit?
Common indicators include intermittent fan failure, a "ghost voltage" reading at the relay, or a motor shaft that does not spin freely by hand. If you measure an open circuit between the common and speed leads with a multimeter, the internal windings have likely failed.

Does this motor include the run capacitor?
No, this motor is a PSC (Permanent Split Capacitor) design and requires an external 4 MFD / 370V capacitor. Using the old capacitor is never recommended when installing a new motor as it may lead to overheating.

How do I verify the speed settings on the 067782202?
You must match the wiring harness to the system’s controller. Ensure the voltage at the terminal block is within the 208-230V range. If the blower wheel is not properly torqued to the flat of the shaft, you may experience excessive vibration or noise.
