Keep your Goodman ARUF25B14AB air handler running reliably with genuine OEM replacement parts from Repair Clinic. The ARUF25B14AB is a two-ton uncased upflow air handler from Goodman’s ARUF series, designed to pair with Goodman heat pumps and air conditioners. As an uncased unit the ARUF25B14AB requires a field-supplied cabinet or plenum enclosure like the evaporator coil, drain pan, and blower assembly are the serviceable components within the unit itself, accessed by opening the field-supplied enclosure rather than removing a factory access panel. Repair Clinic stocks genuine Goodman OEM parts for the ARUF25B14AB including the Goodman air handler blower motor parts, Goodman air handler capacitor parts, and Goodman air handler control board parts.

The Goodman ARUF25B14AB is an uncased air handler without a factory sheet-metal cabinet where the installer provides the enclosure, plenum, or closet installation. Service access requires opening the field-supplied enclosure rather than removing a factory access panel. The blower motor and run capacitor are the most frequently replaced components on the ARUF series. In heat pump applications, where the blower runs year-round in both heating and cooling modes, the run capacitor accumulates more wear per season than in a cooling-only installation.
A motor producing grinding or squealing noise has worn bearings. Schedule replacement before complete bearing failure. A motor running at reduced speed or failing to start almost always has a failed run capacitor rather than a failed motor winding. Test the run capacitor first before ordering a motor replacement as the capacitor costs a fraction of the motor and produces identical symptoms when it fails.
The run capacitor provides the phase-shifted current that enables the PSC blower motor to start and maintain rated speed. A capacitor that has drifted below its rated microfarad value causes the motor to run hot at reduced speed as reducing airflow across the evaporator coil and potentially causing coil icing in cooling mode. Annual capacitance testing before the cooling season extends motor service life significantly.
The ARUF25B14AB control board manages blower speed sequencing across heating, cooling, and continuous fan modes as well as safety switch monitoring. A board fault typically presents as the wrong blower speed in one specific operating mode, or failure to advance the cycle sequence after a valid thermostat call.
The drain pan collects condensate from the evaporator coil during cooling operation. A pan that overflows continuously has a clogged condensate drain outlet. Clear the drain before replacing the pan to confirm the pan is cracked rather than simply overflowing from a blockage.
The ARUF25B14AB is a two-ton Goodman uncased upflow air handler and the 25 in the model number identifies approximately 25,000 BTU two-ton capacity within the ARUF uncased series.
The ARUF25B14AB is a two-ton unit while the ARUF37C14AB is a three-ton unit. The blower motor and coil assemblies are sized differently between these two tonnage classes and they are not interchangeable.
Loud noise from the ARUF25B14AB is most often caused by a blower wheel that has accumulated debris and is running out of balance or a motor bearing that has worn through its lubricant. Clean the blower wheel before ordering a motor replacement.
The ARUF25B14AB is an uncased air handler. The filter is installed in the field-supplied return air plenum or duct rather than inside the unit itself. Keeping the filter clean is critical to prevent the evaporator coil from becoming clogged with airborne debris.
