The Goodman 20201902 is a genuine OEM 23-inch condensate drain hose tube designed for the AMH950704CXAB high-efficiency gas furnace. Cut to the factory 23" length, it routes condensate from the collector box to the drain trap or exit port with the correct reach and bend, preventing sags that trap water. A properly sized OEM tube eliminates the drainage restrictions that trigger pressure-switch and lockout faults.
At a precise 23-inch length, the OEM 20201902 drops in without measuring or trimming. Generic bulk hose must be cut to length and can collapse under the furnace's negative pressure, causing slow drainage. The genuine OEM tube guarantees the right length, diameter, and flexibility for trouble-free condensate flow.
Easy (1 of 5). Straightforward swap — power off, disconnect the old 23" tube, seat the new one at both ends, and secure clamps. Roughly 15 minutes, no special tools.
