Amana-Goodman 20171802S Horizontal Elbow

The Amana-Goodman 20171802S Horizontal Elbow is an OEM replacement component engineered for high-efficiency HVAC condensing units. Serving as the direct functional successor to the 20171801, this elbow is critical for maintaining the integrity of the secondary heat exchanger’s condensate drainage system. Manufactured from robust, chemical-resistant polymers, it withstands the corrosive nature of acidic condensate, preventing leaks that often lead to pressure switch trips or cabinet corrosion. This HVAC drain elbow features precise tolerances to ensure a gas-tight seal when integrated into the collector box assembly. For technicians performing Goodman furnace repair, utilizing this factory-authorized part ensures the unit maintains its original AFUE rating and operational safety. Its rigid construction simplifies installation in tight horizontal applications where standard PVC fittings may lack the necessary clearance or heat resistance. Replace damaged or brittle elbows with this OEM Goodman part to restore optimal fluid dynamics and prevent moisture-related system shutdowns.

Key Benefits

• Direct Cross-Reference: Engineered as the exact replacement for the discontinued 20171801 model.
• Optimized Drainage: Smooth internal radius reduces surface tension to prevent condensate backup.
• Factory Precision: OEM specifications ensure a secure fit with existing horizontal drain lines and collector boxes.
• Industrial Grade Material: High-density construction resists cracking under thermal cycling and chemical exposure.

Common Questions

Is the 20171802S compatible with all Goodman horizontal furnaces?
This elbow is specifically designed for 90% AFUE and above condensing furnaces. You should verify your specific model number against the parts manual to ensure this elbow matches your collector box configuration.

Can I use standard PVC cement on this horizontal elbow?
While the material is compatible with several adhesives, it is typically secured using specialized clamps or high-temperature RTV silicone as specified in the service manual to maintain a service-accessible seal.

What are the symptoms of a failing condensate elbow?
Look for water pooling in the burner compartment, evidence of rust on the furnace floor, or intermittent "limit switch open" or "pressure switch" error codes caused by backed-up drainage.
