York 7900-7631 Door

As a veteran tech, you know that maintaininig the structural integrity of a furnace cabinet is non-negotiable for combustion safety and high-static airflow. The York 7900-7631 Furnace Door (Upper) is the specific OEM furnace replacement part required for the upper service section of York and Coleman DGAA, DGAH, DGPA, and DGPH series gas furnaces. Built from heat-resistant, high-grade white plastic, this assembly is engineered to provide a tight, positive seal against the cabinet frame, preventing bypass air and ensuring the internal furnace components—including the heat exchanger and burner manifold—remain shielded from dust and debris.

This upper door assembly is more than a cosmetic cover; it is a functional component of the filtration system. It features integrated 16x20x1 filter slots, allowing for standard furnace filter replacement without compromising the unit's seal. When a door is cracked or warped, it often leads to limit switch trips or burner interference. Stepping up to a genuine York 7900-7631 replacement ensures the precise 40 1/2" x 19 1/2" fit required for these specific HVAC furnace units, restoring factory-spec static pressure and operational safety.

• Direct OEM Compatibility: Verified fit for York and Coleman DGAA, DGAH, DGPA, and DGPH series units.
• Critical Filtration Support: Includes dual 16x20x1 filter tracks to maintain optimal indoor air quality and blower protection.
• Industrial-Grade Construction: Formulated from durable, high-impact plastic to resist thermal stress and chemical exposure.
• Precision Seal: Ensures the blower compartment remains pressurized, maximizing furnace efficiency and reducing operational noise.

Which models does this part fit?
This door is the designated upper assembly for York/Coleman DGAA, DGAH, DGPA, and DGPH series furnaces. It serves as the direct replacement for older part numbers S1-7900-7361 and S1-37319802010.
