Get your Goodman AWUF190516AB air handler back to dependable performance with genuine OEM replacement parts from Repair Clinic. The AWUF190516AB uses the AWUF series designation, identifying it as an upflow-only configuration distinct from the multi-position ARUF series; this distinction matters because AWUF units are designed exclusively for upflow installation and certain drain pan and limit switch components differ from convertible ARUF-series counterparts. The 19 identifies the approximate 1.5-ton output class. The related AWUF190516BA and AWUF240516BA are adjacent designations within the AWUF platform family at different revisions and output classes respectively. Parts most frequently replaced include the air handler control board, blower motor, blower wheel, capacitor, and transformer.

Goodman AWUF190516AB: Upflow-Only Architecture and AWUF190516BA Revision Cross-Reference
The Goodman AWUF190516AB is an upflow-only air handler, distinct from Goodman’s multi-position ARUF series that supports upflow, downflow, and horizontal installation. Because the AWUF series is upflow-only by design, certain drain pan and limit switch components are specific to this fixed orientation and are not interchangeable with multi-position ARUF parts even at the same nominal output class. The AB revision suffix distinguishes this configuration from the AWUF190516BA; most blower motor and capacitor components are interchangeable between the AB and BA revisions, but control board and wiring harness parts should be confirmed against the AWUF190516AB specific listing. The AWUF240516BA represents a different, larger output class (2-ton) within the same general AWUF platform family. For diagnostic guidance, visit the Goodman air handler troubleshooting section.
AWUF190516AB Component Failures and Diagnostic Sequences
AWUF190516AB Control Board Failure Diagnosis
Symptoms of a failed AWUF190516AB control board include failure to start, erratic blower function, or no response to thermostat commands. Before replacing the board, verify 24-volt control power is present at the board terminals; a failed transformer produces identical symptoms at significantly lower replacement cost.
AWUF190516AB Blower Motor and Capacitor-First Diagnosis
The AWUF190516AB blower motor circulates conditioned air through the duct system. A degraded run capacitor reduces motor torque and speed; test the capacitor before condemning the motor, since this is the lower-cost diagnostic step.
AWUF190516AB and AWUF190516BA Revision Compatibility
Most blower motor, capacitor, and transformer components are interchangeable between the AWUF190516AB and AWUF190516BA revisions. Confirm control board and relay board compatibility against the AWUF190516AB specific listing before ordering from BA revision listings, since firmware and connector configurations can differ between revisions.
AWUF190516AB Drain Pan: Upflow-Specific Component Confirmation
Because the AWUF190516AB is an upflow-only unit, the drain pan and condensate management components are specific to this fixed orientation. Do not substitute drain pan components from multi-position ARUF series listings even at a similar nominal output class, since these are designed for different orientation configurations.

Goodman AWUF190516AB Air Handler Parts FAQ
What does the AWUF designation mean and how is it different from ARUF?
The AWUF series in Goodman’s naming convention identifies an upflow-only air handler, designed exclusively for upflow installation orientation. This differs from the multi-position ARUF series, which supports upflow, downflow, and horizontal installation. Because of this design difference, certain drain pan and limit switch components are specific to the AWUF190516AB and are not interchangeable with ARUF series parts.
Are AWUF190516AB and AWUF190516BA parts interchangeable?
Most blower motor, capacitor, and transformer components are interchangeable between the AB and BA revisions within the AWUF190516 platform. Control board and relay board components should be confirmed against the AWUF190516AB specific parts list before ordering from BA revision listings, since firmware and connector configurations can differ between these revisions.
How do I know if my AWUF190516AB control board has failed?
Symptoms of a failed control board include the unit failing to start at all, erratic or inconsistent blower function, or no response to thermostat commands despite confirmed power to the unit. Before replacing the board, verify 24-volt control power is present at the board terminals, since a failed transformer produces identical symptoms at a lower replacement cost.
Is the AWUF240516BA the same output class as the AWUF190516AB?
No. The AWUF240516BA represents a larger output class (approximately 2-ton) within the same general AWUF upflow-only platform family, while the AWUF190516AB is the smaller approximately 1.5-ton configuration. Blower motors and capacitors are sized per output class and are not interchangeable between these two different capacity designations.
