Window air conditioners are heavy, so get some help removing it from the window. Repairing the fan in a window air conditioner can be as simple as giving its bearings a generous shot of a penetrating oil-lubricant, or it may require replacing the motor assembly. The fan motors used in window air conditioners are inexpensive and designed with welded cases and therefore cheaper to replace than to repair. Remove From Window Unplug the unit from the wall outlet and remove the screws holding the side accordion panels and the window unit in place. Air conditioners are heavy, so have a helper hold the unit securely while you remove the mounting screws. This ensures that the unit does not fall out the window. With your helper, slide the unit from the window and set it on the floor where you can work on it comfortably. Remove the screws holding the case in place and slide it off the unit. Be careful when handling the case because the razor-sharp edges of the sheet metal can cut you. Clean and Check Fan Movement Before you begin working on the air conditioner, clean the unit with a shop vacuum.

Your household vacuum will also do the job if it has a wand attachment. Make sure that you vacuum out the inside of the fan motor housing by placing the mouth of the wand against the holes in the ends of the motor's case. ac unit cost calculatorDirt, dust bunnies and pet hair can accumulate inside the motor and keep the motor's rotor from turning freely. using ac unit to heat poolNext, check to see if the fan blade turns easily by hand. average price for an air conditioning unitCheck to see if the blades have become bent and are rubbing against the fan's shroud. These motors produce very little torque when starting and almost any dirt in the bearings or the slightest contact with the shroud around the blade will keep them from running properly.

Check the Motor's Bearings If the fan blades were bent and the shroud around the blade has not come loose, chances are the motor has bad bearings that will need to be replaced. To check the bearings, grasp the blade in your hand and try moving the shaft from side to side. Any appreciable movement confirms bad bearings, and the motor will need to be replaced. If the blades were not bent but do not turn freely, give the bearings a generous shot of penetrating oil. If that frees up the shaft and the blade turns freely, you have probably saved yourself the cost of replacing the motor. Plug the unit in and see if the fan now runs as it should. Unplug the unit again before replacing the case. Replacing Fan Motor Unplug the motor's wiring harness from the control board. Then remove the screws holding the motor in place. Take the old motor with you to the appliance supply store to make sure you get an exact replacement. You can buy universal fan replacement motors based on their fractional horsepower rating and voltage, but you're better off spending a few extra dollars to get an exact replacement motor.

Replace the motor, reassemble the case, reinstall the unit in the window and plug the unit in. 16 used & new from Sold by Cloud 9 Parts and Fulfilled by Amazon. Do it yourself and save.

The A/C fan motor provides the necessary force to rotate the fan inside of the A/C system and blow air into the cabin of the vehicle. The motor is part of the fan unit and comes with a replacement fan. How do you tint tail lights? How do you change cabin air filter? The A/C fan is typically located within the dash, behind the cabin air filter. Automotive A/C fans require a decent amount of lubrication to ensure a long lifespan. Over time, dirt and corrosion settle into the fan motor and decrease performance until the fan can no longer operate. New replacement fans come with a motor and are sold as a package for the specified vehicle.

If the fan is being serviced by the vehicle owner and not a certified technician, it is advised that the fan be thoroughly inspected before a new unit is inserted. A blown fuse may cause a fan to malfunction. Replacing the fan is not advised at this point. While the vehicle is off, the owner should follow the directions specific to the vehicle being serviced, as stated by the manufacturer, to access the A/C fan unit safely. Once the fan has been located, the owner should check to see if it spins smoothly. If there is a large amount of resistance, the fan has reached the end of its lifespan and needs to be replaced by a new unit. A smooth spinning fan that does not function is likely the victim of an electrical issue. It should be serviced by a certified automotive technician who can test the voltage being received by the unit and replace a fuse if necessary.
