Daikin-McQuay 403585001 Pressure Switch
The Daikin-McQuay 403585001 High Pressure Switch is an essential safety component designed for heavy-duty HVACR applications where refrigerant pressure monitoring is critical. As an OEM Daikin pressure switch, this SPST (Single Pole Single Throw) control—equivalent to the Danfoss ACB-2UC27 061F9093—acts as a failsafe to protect compressors from catastrophic failure. When head pressures exceed safe operating limits, the switch breaks the electrical circuit, preventing HVAC compressor damage and maintaining environmental safety.
This HVAC high pressure control is engineered for a precise cut-out, making it ideal for Daikin McQuay maintenance in both air conditioning and heat pump setups. Its compact, cartridge-style design ensures compatibility with standard refrigerant lines, allowing for efficient field replacement. By integrating this OEM replacement part, technicians ensure the system operates within manufacturer-specified pressure envelopes, optimizing overall energy consumption and preventing premature component wear caused by system over-pressurization.
Key Benefits:- System Protection: Acts as a primary safety line to prevent compressor overheating and mechanical failure due to high refrigerant pressure.
- OEM Precision: Guaranteed compatibility with Daikin-McQuay equipment, ensuring accurate trip points and reliable performance.
- Durable Construction: Built to withstand the rhythmic vibration and thermal stressors of commercial and residential condensing units.
- Simplified Diagnostics: Standard SPST configuration allows for straightforward continuity testing during routine service calls.
What causes this switch to trip in an HVAC system?
Tripping is usually caused by restricted airflow over the condenser coils, a failing condenser fan motor, or an overcharge of refrigerant. Direct blockages or extremely high ambient temperatures can also spike pressures above the set-point.
Is the 403585001 pressure switch a manual or automatic reset?
This specific model is typically designed as an automatic reset for high-pressure monitoring, though technicians should always verify the system's control logic to ensure the restart sequence is handled safely by the main board.
Can I test the functionality of this switch with a multimeter?
Yes, under normal operating pressures (below the cut-out threshold), the switch should show low resistance (continuity). If the switch is open (OL) while system pressures are within normal range, the internal diaphragm or contacts have likely failed.
