This part is out of stock right now, so it cannot be added to the cart.
This motor spins the fan to move air across the condenser coil. If the fan stops turning, heat builds up quickly, causing the cooling equipment to overheat and shut down.

What the Condenser Fan Motor Does
The condenser fan motor plays a critical role in the cooling cycle. It draws or pushes air across the condenser surface to remove heat absorbed during operation. Continuous airflow keeps internal operating pressures within safe limits.
When this motor fails, heat cannot escape. The equipment will trigger internal safety controls or overheat, leading to unexpected shutdowns.
Dimensions and Physical Specs
When verifying an old motor labeled 12292701, check the physical dimensions to ensure the replacement fits inside the housing and mounting assembly.
The dimensions for this part number are:
- Height: 3.25 in
- Length: 8.0"
- Width: 4.4 in
How to Match a Replacement Motor
Matching a condenser fan motor requires checking electrical ratings and mechanical setup against your old unit. Never install a motor with mismatched power ratings.
Use these standard match rules when comparing replacement motors:
- HP: must be the same.
- RPM and volts: must be the same.
- Rotation and shaft: match, or pick a reversible motor.
Troubleshooting and Safe Replacement
A fan that hums but will not spin is often caused by a failing capacitor rather than a dead motor. A capacitor costs less to replace, so check its condition before removing the motor.
If the motor itself has failed, follow these safe service guidelines:
- Shut off power at the breaker and pull the disconnect switch. Test the lines to verify no voltage is present.
- Discharge the capacitor using an insulated tool before handling any wire connections.
- Take a photo of every wire connection on the old motor to record the exact layout.
- Remove the mounting hardware and carefully detach the fan blade from the shaft.
- Install the replacement motor, secure the mounts, and move wires one at a time to the matching spots.
- Remember that a new motor often needs a new capacitor rated specifically for it.
Read your old part
- Locate the manufacturer data tag on your existing condenser fan motor housing.
- Check that the part number stamped on the metal casing reads 12292701.
- Compare the physical size to the listed specs: height of 3.25 in, length of 8.0", and width of 4.4 in.
- Verify that the horsepower, voltage, and RPM ratings on the label match your replacement requirements.
When to call a pro
Hire a licensed HVAC technician for any step you are not sure you can do safely. If you encounter line voltage wiring issues or cannot safely test for power, stop work and contact a licensed professional.
Questions
Why is my condenser fan motor humming but not spinning?
A fan that hums but will not spin is often a bad capacitor, not a bad motor. A capacitor costs less, so check it first before replacing the motor.
What ratings must match when choosing a replacement condenser fan motor?
The horsepower (HP), RPM, and volts must be the same as the original part. The rotation direction and shaft dimensions must also match, or you should select a reversible motor.
Do I need to replace the capacitor when installing a new motor?
A new motor often needs a new capacitor rated specifically for it. Always check the rating requirements listed on the new motor.
What safety precautions are required before replacing this motor?
Turn off power at the breaker and the outdoor disconnect, then test for power before touching anything. A capacitor can hold a charge even with power disconnected, so it must be discharged with an insulated tool.
