Key Features:
- Official OEM Trane motor (part number MOT18625)
- Electrical rating: 230V, 1-phase
- Output: 1/4 HP
- Speed: 825 RPM
- Frame: 48 frame

Compatibility & Applications:
- Listed for Trane HVAC equipment (model-specific).
- Must only be used where the manufacturer specifies this exact part number: MOT18625 (or explicitly lists it as the approved replacement for the part numbers above).
Installation & Operation Notes:
- Installation should be performed by a qualified HVAC service technician.
- Reference the unit's service/installation manual and wiring diagram for the exact model to confirm correct wiring, mounting, rotation/airflow requirements, and any required accessories (such as the correct capacitor for that application).
- Manufacturer guidance emphasizes following published instructions and not modifying equipment/electrical wiring outside the manufacturer's requirements.
Maintenance & Troubleshooting:
- Customer reviews commonly describe replacement after a condenser fan motor failure (e.g., overheating/thermal-protection cycling on a non-OEM substitute), with MOT18625 restoring normal operation.
- A recurring theme in reviews is that substitute motors may require different capacitors than the OEM setup; verify capacitor requirements in the unit documentation when replacing a motor.
- If problems persist after installation (overheating, cycling, abnormal operation), use the unit's diagnostic procedures to confirm correct wiring, correct capacitor selection, and proper fan retention/positioning per the equipment documentation.
User Reviews & Q&A Summary:
- Common positive themes:
- "Fits perfectly" / works as expected.
- Prefer OEM performance over some aftermarket "kit" motors (including reports of aftermarket motors cycling on thermal protection).
- Common caution themes:
- Some users report design/installation differences versus the original (e.g., wire/conduit routing not lining up the same).
- One review recommends adding a retainer screw/clip to help prevent the fan from coming off (installation practice note).
- Mixed feedback includes a report of incorrect compatibility advice and a note that capacitor pairing may differ when using substitutes.
