Keep your Trane TWE024C140B0 air handler performing reliably with genuine OEM replacement parts from Repair Clinic. The TWE024C140B0 is a two-ton cased upflow air handler from Trane’s TWE series, designed to pair with R-410A or R-22 outdoor units in upflow configurations. The B0 revision of the TWE024C140 platform shares most blower motor and coil components with the A0 revision. In heat pump applications the blower runs year-round, making the run capacitor a higher-wear item than in cooling-only installations. Repair Clinic stocks genuine Trane OEM parts for the TWE024C140B0 including the Trane air handler blower motor parts, Trane air handler capacitor parts, Trane air handler control board parts, and Trane air handler drain pan parts.

TWE024C140B0: Trane Two-Ton Cased Upflow Air Handler and the B0 Production Revision
The Trane TWE024C140B0 is the two-ton configuration of the TWE cased upflow series, positioned below the three-and-a-half-ton TWE042C140C0 on the same platform architecture. The two-ton blower motor assembly must not be substituted with motors from the three-and-a-half-ton or four-ton TWE configurations. Confirm the full TWE024C140B0 model designation from the data plate before ordering a replacement control board, as the B0 revision may differ from the A0 revision in board programming.
Most Replaced Parts on the Trane TWE024C140B0
Blower Motor for the Trane TWE024C140B0
The two-ton blower motor on the TWE024C140B0 must not be substituted with motors from larger-tonnage TWE configurations. In heat pump applications this motor runs year-round, accumulating more annual hours than in a cooling-only installation. Test the run capacitor before ordering a replacement motor, as a failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
Run Capacitor for the TWE024C140B0
The run capacitor provides the phase-shifted current the PSC blower motor needs to start and maintain rated speed. A capacitor reading more than 10% below its rated microfarad value causes the motor to run hot at reduced airflow. Annual testing before the cooling season catches a weakening capacitor before it fails.
Control Board for the Trane TWE024C140B0
The TWE024C140B0 control board manages blower speed sequencing across heating, cooling, and continuous fan modes and safety switch monitoring. Confirm the full TWE024C140B0 model designation including the B0 revision suffix from the data plate before ordering a replacement board.
Drain Pan for the TWE024C140B0
The condensate drain pan collects moisture from the evaporator coil during cooling operation. A drain pan that overflows continuously has a clogged condensate drain outlet. Clear the drain line before replacing the pan to confirm the pan itself is cracked rather than simply overflowing from a downstream blockage.

Trane TWE024C140B0 Air Handler Parts FAQ
What ton size is the Trane TWE024C140B0 air handler?
The TWE024C140B0 is a two-ton Trane air handler. The 024 in the model designation identifies 24,000 BTU capacity corresponding to the two-ton classification within the TWE cased upflow series.
What is the difference between the Trane TWE024C140B0 and the TWE042C140C0?
The TWE024C140B0 is a two-ton unit while the TWE042C140C0 is a three-and-a-half-ton unit on the same TWE cased series. Blower motor assemblies are sized for their respective tonnages and must not be cross-substituted between the 024 and 042 configurations.
Why is my Trane TWE024C140B0 coil icing up?
Coil icing on the TWE024C140B0 is most commonly caused by a low refrigerant charge in the matched outdoor unit, restricted airflow from a clogged filter or dirty coil fins, or a blower motor running at reduced speed from a failed run capacitor. Replace the filter before inspecting airflow and refrigerant charge.
Are the Trane TWE024C140B0 and TWE024C140A0 parts interchangeable?
The TWE024C140B0 and TWE024C140A0 are successive production revisions of the same two-ton TWE cased upflow air handler. Most blower motor and coil components are shared between both revisions. The control board may differ between the B0 and A0 revisions.
