User Reviews & Q&A Summary:
An OEM replacement motor for Rheem HVAC equipment, used as a condenser fan motor to move outdoor air across the condenser coil and help prevent compressor overheating.
Key Features:
- Motor ratings: 208/230V, 1/5 HP, 1075 RPM
- An official OEM motor for Rheem HVAC equipment
- Rheem describes the matching replacement as a condenser fan motor used to transfer heat to outdoor air and support normal condenser operation
Compatibility & Applications:
- Intended for Rheem HVAC applications where the equipment specifies motor part number 51-23055-11
- The provided sources do not include a definitive model list; compatibility is typically confirmed by matching the unit model/serial and required motor specifications
- Must only be used where the manufacturer specifies this exact part number: 51-23055-11
Installation & Operation Notes:
- Installation should be performed by a qualified HVAC service professional
- Refer to the unit's service/installation manual for wiring, rotation, and mounting requirements
Maintenance & Troubleshooting:
- Rheem describes this component as critical to condenser heat rejection; condenser fan motor issues can contribute to poor cooling and compressor overheating
- Reviews and Q&A commonly associate replacement with a non-running/failed outdoor fan motor; replacing the motor often restores normal condenser fan operation
- If a replaced motor overheats or shuts down (reported by a small number of reviewers), troubleshooting should continue per the unit's service manual to confirm correct application, wiring, and system conditions
User Reviews & Q&A Summary:
- Common themes: direct replacement fit, restores outdoor fan operation, and "works as expected," with multiple buyers noting straightforward installation
- Frequent mentions of good fulfillment experience (availability and delivery speed)
- Recurring Q&A topics: confirming compatibility with specific Rheem model numbers and guidance on extra wiring leads and capacitor sizing/need (handled via support and unit documentation)
- Less common negatives: one reviewer reported overheating/shutoff after a short run time, and another disputed OEM labeling (noting the motor received was branded differently)

It's not OEM and not a Ream motor.
They are selling Protech motors and listed the motor they are selling as OEM. They are not.

Great product, needs better instructions
Great shipping time and the product was packaged securely. After locating a video online I was able to confidently install the motor without issue. I just wish there were better instructions that the simple picture diagram with no writing on it.

Q: Do I need a new capacitor for this motor or use the existing Rheem Capacitor?
Asked by tom 14 years ago
Add your answer
Verified Reply- PexSupply StaffThe manufacturer does recommend replacing the capacitor if the motor is being replaced, but it is not required. The capacitors are easily replaceable so it is suggested to put in a new one when putting in a new motor.
