Restore reliable airflow and system performance from your Goodman ARUF182416AA air handler with genuine OEM replacement parts from Repair Clinic. The ARUF182416AA is a 1.5-ton multi-position air handler in Goodman’s ARUF series; the 18 in the model number identifies the 1.5-ton (18,000 BTU) output class, and the 24 identifies the cabinet width designation. As the smallest common residential air handler output class, the ARUF182416AA blower motor and capacitor specifications differ from larger ARUF configurations; confirm components against the ARUF182416AA specific parts list rather than borrowing from ARUF24 or ARUF30 listings. The Goodman ARUF1824 shortened designation in some catalog searches refers to the same 1.5-ton ARUF platform as the ARUF182416AA. Parts most frequently replaced include the blower motor, run capacitor, control board, and float switch. Browse the full Goodman air handler parts catalog.
ARUF182416AA at 1.5 Tons: Smallest ARUF Output Class and Component Specification Confirmation
The Goodman ARUF182416AA is the 1.5-ton (18,000 BTU) configuration in Goodman’s ARUF series, the smallest capacity class in the residential ARUF platform. The 1.5-ton output class uses a smaller blower wheel and lower motor horsepower than the 2-ton, 2.5-ton, or 3-ton ARUF configurations; substituting a blower motor from a larger ARUF output class produces excess airflow noise and potential coil velocity issues in the 1.5-ton cabinet. The Goodman ARUF1824 designation appearing in abbreviated catalog searches refers to the same 1.5-ton ARUF platform as the ARUF182416AA; parts searches under ARUF1824 return compatible ARUF182416AA components. The 16 in the model number indicates the electric heat strip capacity designation; confirm whether your installation includes the electric heat strips before ordering any heat strip-specific components. The Goodman ARUF182416AA manual documents blower speed tap settings and the drain pan access location. For diagnostic guidance, visit the Goodman air handler troubleshooting section.
ARUF182416AA Component Service and 1.5-Ton Platform Considerations
ARUF182416AA Blower Motor and Capacitor Service at 1.5-Ton Output Class
The ARUF182416AA blower motor circulates conditioned air from the 1.5-ton evaporator coil through the duct system. At the smallest ARUF output class, the motor operates at a lower horsepower rating than larger configurations; confirm the motor specification from the ARUF182416AA parts list before ordering. Test the ARUF182416AA capacitor before condemning the motor; a capacitor drifted out of specification produces blower speed reduction at significantly lower replacement cost. Browse Goodman air handler blower motor parts.
Goodman ARUF182416AA Control Board Fault Diagnosis
The ARUF182416AA control board manages blower speed sequencing and communicates with the matched outdoor unit. Before replacing the control board, confirm 24-volt input voltage at the board terminals; a failed transformer produces board unresponsiveness at lower cost. Browse Goodman air handler control board parts.
ARUF182416AA Evaporator Coil Frosting and Airflow Causes
The ARUF182416AA evaporator coil will frost during cooling operation when airflow through the coil drops below the design threshold. Coil frosting on this unit is most commonly caused by a clogged air filter, a blower motor running below rated speed from a degraded capacitor, or supply or return vents that have been closed. Replace the filter first and test the blower motor capacitor before any refrigerant system diagnosis.
ARUF182416AA Float Switch and 1.5-Ton Condensate Volume
The ARUF182416AA float switch activates when condensate overflows the secondary drain pan. At 1.5-ton output the condensate production volume is lower than larger configurations, but a completely blocked drain line will still trigger the float switch during sustained cooling operation. Clear the drain line before resetting the float switch.

Goodman ARUF182416AA Air Handler Parts FAQ
What tonnage is the Goodman ARUF182416AA?
The Goodman ARUF182416AA is a 1.5-ton (18,000 BTU) air handler. The 18 in the model number identifies the 1.5-ton output class. Blower motors and blower wheels from larger ARUF configurations are not interchangeable with the 1.5-ton ARUF182416AA components; always confirm the model number when ordering these components.
Is the Goodman ARUF1824 the same as the ARUF182416AA?
Yes. The Goodman ARUF1824 designation is an abbreviated catalog reference for the same 1.5-ton ARUF platform as the ARUF182416AA. The 18 identifies the 1.5-ton output class, the 24 identifies the cabinet width, the 16 identifies the electric heat strip capacity designation, and the AA is the revision suffix. Parts searches under ARUF1824 return ARUF182416AA-compatible components.
Are ARUF1824 and ARUF182416AA parts interchangeable with larger ARUF models?
The blower motor and blower wheel are specific to the 1.5-ton ARUF182416AA output class and are not interchangeable with motors from larger ARUF configurations. The run capacitor, control board, and float switch may share part numbers with other ARUF platform variants; confirm against the ARUF182416AA specific parts list before ordering these components from larger ARUF listings.
Why is the ARUF182416AA evaporator coil frosting?
Evaporator coil frosting on the ARUF182416AA during cooling operation is caused by airflow below the design threshold through the coil. The most common causes are a clogged air filter reducing airflow before the blower, a blower motor running below rated speed from a degraded run capacitor, or closed supply and return vents reducing total system airflow. Test the filter, capacitor, and vent positions in that order before any refrigerant system diagnosis.
