Amana-Goodman 0130M00074S Pressure Switch

The Amana-Goodman 0130M00074S Pressure Switch is a critical safety component designed for high-pressure monitoring in residential and light commercial HVAC systems. This OEM replacement high-pressure switch operates with a 420-660 PSI trip range, ensuring the compressor is protected from excessive system pressures that could lead to catastrophic failure. As a direct replacement for the 0130M00074, this component is engineered for precise differential pressure sensing and is compatible with various Goodman and Amana heat pumps and air conditioning units. The switch features a single-pole, single-throw (SPST) configuration, typically functioning in a normally closed (NC) position to maintain the control circuit until a high-pressure limit is reached. For technicians performing system diagnostics and repair, this switch provides the exact electrical specifications and mechanical connection required for a reliable fix, maintaining the original equipment manufacturer's safety standards and system performance integrity.

• Direct OEM Compatibility: Engineered as the specific 0130M00074S replacement part for seamless integration into Amana and Goodman systems.
• Precise Pressure Calibration: Features a factory-set 420 PSI cut-out and 660 PSI cut-in range to prevent compressor overheating and mechanical damage.
• Durable Construction: Built to withstand high-cycling environments common in high-efficiency HVAC units.
• Simplified Installation: Standard 1/4 inch female flare fitting and spade terminals facilitate efficient field replacement for HVAC contractors.

Common Questions

What causes a high-pressure switch to trip on a Goodman unit?
A trip usually indicates restricted airflow, failed condenser fans, or overcharged systems. If the refrigerant pressure exceeds 660 PSI, the 0130M00074S opens the circuit to shut down the compressor.

Is the 0130M00074S a manual or automatic reset switch?
This is an automatic reset pressure switch, meaning it will close the circuit once the system pressure drops back below the 420 PSI threshold.

Can I use this switch with R-410A systems?
Yes, the 420-660# rating is specifically calibrated for the operating pressures of R-410A refrigerant applications.
