Amana-Goodman B1789857 Orifice
The Amana-Goodman B1789857 Orifice is a high-precision R410A .057 restrictor orifice engineered to maintain the performance of residential and light commercial cooling systems. This genuine Goodman replacement part acts as the primary metering device, regulating the precise volume of refrigerant entering the evaporator coil. By ensuring the correct flow rate, this HVAC expansion orifice prevents liquid slugging and evaporator freeze-ups, resulting in superior energy efficiency and temperature consistency. Designed specifically for Amana and Goodman air conditioners and heat pumps, the B1789857 provides the reliable fit and durability required for long-term system health. Whether you are performing a routine repair or restoring a unit during a coil replacement, using this OEM restrictor piston ensures your equipment operates within original manufacturer specifications.
Key Benefits:
- Optimized Efficiency: Maintains the exact R410A refrigerant flow required for maximum SEER ratings.
- System Longevity: Helps prevent compressor damage by ensuring proper superheat levels.
- Exact Metering: Features a calibrated .057 orifice size for highly accurate pressure drops.
- OEM Integrity: A direct factory replacement that guarantees compatibility with Amana-Goodman evaporator coils.
Common Questions:
What is the function of the .057 orifice in an AC system?
The .057 orifice serves as a fixed-bore metering device that reduces high-pressure liquid refrigerant to a low-pressure liquid/vapor mix before it enters the evaporator coil.
Can I use this orifice with R22 refrigerant?
No, the B1789857 is specifically designed for R410A systems. Using it with the wrong refrigerant type can lead to poor cooling performance or system failure.
How do I know if the B1789857 is the correct size for my unit?
Orifice sizing is determined by the tonnage and SEER rating of your condenser and coil. Always refer to your unit's technical data sheet or contact our team to verify that the .057 size matches your specific configuration.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
