Removing the blower wheel from a Panasonic mini split air conditioning unit can be a delicate task, but with the right approach and attention to detail, it can be accomplished successfully. This comprehensive guide will walk you through the step-by-step process, providing technical insights and expert-level advice to ensure a smooth and efficient blower wheel removal.
Preparing for Blower Wheel Removal
Before you begin, it’s crucial to ensure that the Panasonic mini split unit is disconnected from the power source to prevent any electrical hazards. Additionally, have the following tools readily available:
- Screwdriver set (both flathead and Phillips head)
- Hex key set
- Pliers
- Compressed air (optional)
- Cleaning supplies (water, mild detergent, and a soft-bristled brush)
Removing the Front Cover

- Locate the screws on the bottom of the Panasonic mini split unit. These screws are typically found along the lower edge of the front panel.
- Using the appropriate screwdriver, carefully remove the screws, taking note of their positions for reassembly.
- Gently pull the front cover away from the unit, being mindful of any wiring or connections that may be attached.
Lowering the Drain Pan
- Observe the drain pan, which is not physically attached or secured to the unit. It is held in place by tabs on the bottom, left, right, and middle.
- Carefully disengage the tabs and lower the drain pan to gain better access to the blower wheel and its surrounding components.
Loosening the Set Screw
- Locate the set screw that holds the blower wheel onto the blower motor. This set screw is typically found on the far right side of the blower wheel.
- Spin the blower wheel until you find an opening where you can insert your screwdriver.
- Using the appropriate screwdriver, slowly loosen the set screw, taking care not to strip the threads.
Removing the Evaporator Coil Screws
- Identify the three screws on the left side of the evaporator coil.
- Using the appropriate screwdriver, remove these three screws.
- Once the screws are removed, you can carefully lift the evaporator coil out towards you.
Extracting the Blower Wheel
- With the evaporator coil removed, you should now have clear access to the blower wheel.
- Gently grasp the blower wheel and pull it out, taking care not to damage the bearing located on the left side of the wheel.
Cleaning the Blower Wheel
- Avoid using harsh chemicals when cleaning the blower wheel. Instead, opt for a gentle cleaning solution, such as a mild detergent and water.
- Use a soft-bristled brush to gently remove any accumulated dirt, dust, or debris from the blower wheel.
- If desired, you can use compressed air to blow off any loose particles before using the water-based cleaning solution.
- Ensure that the bearing on the left side of the blower wheel is not damaged or lost during the cleaning process.
Reassembling the Panasonic Mini Split
To reassemble the Panasonic mini split unit, simply reverse the steps taken to remove the blower wheel:
- Carefully reinsert the blower wheel, ensuring that the bearing is properly aligned and secured.
- Replace the evaporator coil and secure it with the three screws on the left side.
- Raise the drain pan and engage the tabs to secure it in place.
- Reattach the front cover and secure it with the screws along the bottom edge.
- Reconnect the unit to the power source and test the operation of the Panasonic mini split.
Remember, it’s essential to take your time and follow the steps carefully to avoid any damage to the unit or its components. If you encounter any difficulties or have additional questions, it’s recommended to consult the manufacturer’s instructions or seek the assistance of a qualified HVAC technician.
