Amana-Goodman 2820007S Collector Box Assy

The Amana-Goodman 2820007S Collector Box Assy is a critical OEM furnace replacement part engineered for high-efficiency condensing gas furnaces. This assembly is specifically designed to manage the collection and drainage of corrosive acidic condensate within the secondary heat exchanger system. It provides a precise fit for Amana, Goodman, and Daikin gas furnaces, including specialized compatibility with the GMPN120-5 and GMN120-5 model series. Constructed from durable, heat-resistant composite materials, the 2820007S ensures a leak-proof seal, preventing moisture infiltration that can lead to inducer motor failure or manifold pressure issues. For technicians performing HVAC furnace repair, replacing a cracked or warped collector box with this genuine factory component restores the structural integrity of the combustion air circuit. Prioritizing HVAC part compatibility with this factory-authorized assembly ensures optimal pressure switch performance and prevents safety circuit trips during high-demand heating cycles.

• Precision OEM Fit: Eliminates the need for field modifications, ensuring a direct match for Amana-Goodman furnace models.
• Corrosion Resistance: Engineered to withstand the acidic nature of flue gas condensate for long-term reliability.
• Improved Pressure Delta: Helps maintain accurate vacuum pressure readings for the draft inducer and pressure switch.
• Reduced Callbacks: Using genuine HVAC replacement parts ensures factory-spec drainage and prevents recurring water leakage.

What causes a collector box to need replacement?
Repeated thermal expansion and contraction can cause the composite material to crack, while clogged drain ports can lead to water backup and system lockout.

Is the gasket included with the 2820007S assembly?
This assembly typically includes the mounting flange and ports, though it is standard practice to verify the condition of the secondary heat exchanger interface during installation.

Will this work with 120,000 BTU GMPN models?
Yes, this specific collector box assembly is indexed for the 120k BTU chassis found in the GMPN and GMN series.
