ICP 1091257 Fan Blade

Understanding the 1091257 Specifications

A replacement fan blade must match the original dimensions and airflow design to move air correctly. The specifications for part number 1091257 provide the key details you need to check against your existing blade.

Every measurement on this blade serves a specific mechanical purpose:

• Diameter: 18". This is the total width across the blade tips.
• Rotation: CCW. This stands for counterclockwise. The blade must turn in this direction to pull or push air the right way.
• Dimensions: 1/2 inch on the intake side. This spec defines the physical size and position on the intake side of the assembly.

How to Confirm a Match

When you hold an old fan blade, confirm the physical ratings and numbers before attempting a swap. An incorrect size or rotation will hurt cooling performance and strain the motor.

Use these general match checks to ensure your replacement is suitable:

• Specs: Match the label on your old part to confirm ratings.
• Size: Ensure it fits the same space inside the outdoor cabinet without rubbing the coil or grill.
• Connections: Verify that the mounting setup and fittings match the original design.

Signs of Failure and Safe Replacement Steps

Fan blades can crack from stress, bend from storm debris, or wobble out of balance over time. A bent or cracked blade often causes heavy vibration, rattling, or poor cooling. If your fan hums but will not spin, remember that a bad capacitor is often the cause rather than a broken blade or motor.

If the blade itself is damaged and needs to be replaced, follow these steps to work safely:

1. Turn off power at the household breaker and pull the outdoor disconnect switch.
2. Test the unit with a meter to verify that power is fully disconnected.
3. Take a photo of the old part, its mounting position, and its wiring before you remove anything.
4. Remove the top fan grill to reach the blade assembly.
5. Loosen the mounting screw holding the blade to the motor shaft and carefully pull the old blade free.
6. Place the new blade into position, secure the hardware firmly, and spin it by hand to confirm it clears the housing.
7. Reattach the protective grill, restore power, and monitor the unit as it starts.

Read your old part

1. Locate the part number stamped or printed directly on your old fan blade.
2. Check that the part number matches 1091257.
3. Measure the diameter across the blade tips to confirm it is 18".
4. Check that the rotation is CCW (counterclockwise).
5. Confirm the dimensions detail of 1/2 inch on the intake side matches your original setup.
