York S1-028-17090-000 Drain Pan

The York S1-028-17090-000 is the OEM 2-row N-coil drain pan, 14.5 size for select York evaporator coil and air handler assemblies, supplied under York's Source 1 parts line. The drain pan sits under the evaporator coil and catches the condensate that forms when warm, humid indoor air is cooled below its dew point, then directs that water to the drain connection and out of the system. An N-coil gets its name from the N-shaped arrangement of its coil slabs, and the 2-row designation refers to the number of tube rows in the coil, so this pan is specific to that coil configuration.

York lists drain pans by coil style, row count and size, and the numbers are close together, so the number matters. The related S1-028-17091-000 is the 2-row N-coil 17.5 pan, S1-028-17097-000 is the 2-row N-coil Up 17.5 pan, S1-028-17096-000 is the 2-row N-coil Up 14.5 pan, S1-028-17094-000 is the 3-row N-coil 21.0 pan and S1-028-17098-000 is the 2-row N-coil Up 21.0 pan. Each is a separate part; the 14.5 in S1-028-17090-000 is York's size designation, so compare it with the pan you are replacing and with the row count and style of your coil before ordering.

A pan that is cracked, warped, corroded or chronically clogged will leak, and the result is water at the air handler, a wet insulation and subfloor, mold growth or a tripped float switch. When you swap the pan, clear the primary drain line and the secondary drain, inspect the drain fitting and gaskets, and confirm the condensate trap and any float switch are working before putting the coil back. Support the coil carefully while the old pan is removed, and make sure the new pan seats level and slopes toward the drain so water cannot pool. Pooled water in a pan is the usual cause of algae slime and odors, so a clean, correctly seated pan is as much about indoor air quality as it is about leak prevention.

Key Benefits

• OEM Configuration: Made for York 2-row N-coil assemblies, so the pan matches the coil footprint and drain layout the equipment was built around.
• Stops Condensate Leaks: A sound pan keeps condensate contained and flowing to the drain line instead of onto ceilings, floors and insulation.
• Separate Sizing Options: The 17090 / 17091 / 17094 / 17096 / 17097 / 17098 family lets you choose the correct row count and size for the coil you have.
• York Source 1 Number: Ordering by S1-028-17090-000 avoids the mix-ups that happen when pans differ by only a digit.

Common Questions

• What is this part? It is a York 2-row N-coil drain pan, 14.5 size, the pan that collects and drains evaporator coil condensate.
• How is it different from S1-028-17091-000? The S1-028-17091-000 is listed as a 2-row N-coil 17.5 pan; the S1-028-17090-000 is the 14.5 size. They are separate parts.
• What should I check before replacing the pan? Confirm the coil is a 2-row N-coil, compare the size to the pan you are removing, and check the drain line and float switch so the new pan does not overflow for the same reason.
