Daikin-McQuay 073397201 Switch

As a field-hardened technician, you know that keeping older Daikin-McQuay units operational requires precise HVAC replacement parts that match original specifications. The Daikin-McQuay 073397201 is a critical 5 pushbutton switch assembly designed for manual control of fan speeds and operational modes in specialized air conditioning and terminal units. Commonly identified in the field as the McQuay 073397201 OEM switch, this component ensures steady electrical contact and responsive mechanical switching for commercial HVAC systems. Manufactured to meet the specific voltage and amperage requirements of Daikin and legacy McQuay equipment, it serves as a direct OEM HVAC control switch for technicians performing maintenance on PTAC units and fan coils. Note that this 5-button manual switch is often a non-returnable item due to its specific electrical application, and it replaces older versions like the 73397201. For PMRS model PTACs, always verify if a separate interface kit is required before installation. Rely on this genuine Daikin part to restore manual override and multispeed functionality without compromising the control circuit integrity.

• Direct OEM Compatibility: Ensures seamless integration with Daikin-McQuay 073397201 designated systems without field modifications.
• Rugged 5-Button Design: Built for high-cycle manual operation in demanding commercial HVAC environments.
• Tactile Feedback: Provides clear mechanical engagement for speed selection, reducing user error and control board communication faults.
• Standardized Housing: Fits existing chassis cutouts for fast, contractor-grade installations during service calls.

Is this switch compatible with all McQuay PTAC models?
This HVAC pushbutton switch is specific to certain series. If you are working on a PMRS model PTAC, you may need a separate conversion kit or internal wiring harness to ensure full functionality.

Can I replace individual buttons or do I need the full 073397201 assembly?
While the buttons have individual part numbers for color coding, replacing the entire 073397201 assembly is recommended for maximum reliability of the internal electrical contacts.

Will this switch resolve fan speed issues?
If the motor is verified as operational but the unit fails to change speeds, replacing this multispeed manual switch is the standard diagnostic step to restore proper airflow control.
