Device is Overheating
Your fan is radiating heat.
The Fan is Dirty
Accumulated dust in the fan blades and rotor can cause the fan to overheat. Inspect these components for dirt and debris that may be obstructing propeller rotation. Clean the fan blades with an air duster. Make sure you spray off all of the dust inside and out. After cleaning, test the fan to see if it still overheats. If so, the motor is likely the issue.
The Fan Needs Lubrication
If the fan’s spinning rotor doesn't have proper lubrication, it can generate friction and heat. Remove the fan grill and bladesand lubricate the inside of the rotor with household lubricant oil or turbine oil.
The Motor Needs Lubrication
If your fan is clean, check the internal bearings for rust. If it is not visibly rusty, the gears or clutch knob may need to be lubricated. After removing the grill and the motor housing, lubricate the gears and the clutch knob with lubricant oil or turbine oil. Rotate the fan rotor by hand and spray again. Do this several times and wait 10 minutes. Turn the fan on to see if it still overheats.
Moisture has Corroded the Internal Bearings
If you see rust on the internal bearings, moisture has corroded them, causing them to seize. Water or moisture should never enter the motor. If these parts have rusted, the fan can only be fixed by replacing them. You can check for rust by removing the grill and the motor housing.
Your blades are making squeaking noises.
The Blades are Rusty or Dirty
If your fan blades are rusty or dirty upon inspection, remove the fan grill and the blades. After removing the blades, clean them thoroughly with mild soap and a damp, but not dripping, cloth or sponge, then thoroughly remove the soap film with clear water. Make sure not to splash water or any other liquid into the motor. Dry and apply lubricant oil or turbine oil to the base of the blades. Then screw the blades back onto the rotor, reattach the grill, and turn on the fan to see if the noise persists.
Screws that Hold the Blades to the Fan are Loose
There is one screw at the center of the base of the blades that holds the blades to the fan. Check to see if this screw is loose and if it is, tighten the screw.
Screw is Rusted/Corroded
Remove the fan grill and unscrew the single screw that holds the blade array to the base. Check this screw to see if it is rusty, warped or stripped. If it shows damage, replace it with a new screw. Replace the blade array and grill.
Fan blades make a rattling sound
Fan Grill is Loose
A loose fan grill can contact the blades and makes noise. Remove the grill ring with a screwdriver and unfasten the grill. Wipe off the grill’s outer ring where it attaches to the fan. Then reattach the grill, being careful to line up the grill and the fan correctly. Replace the grill ring around the grill, making aligned correctly, and insert the screw.
Blade Array is Loose
The blade array not being firmly attached to the rotor can also allow contact between the blades and grill and make noise. Make sure the screw at the base of the blade array is tightened.
Blade Array is Incorrectly Positioned
If the blade array is positioned too far forward or backward it can contact the fan grill and make noise.
Appliance Won’t Power On
Fan blades won’t spin when fan is plugged in and turned on
Fan Needs Lubricating
If the fan blades don’t move after cleaning, turn the fan off again. Spray the fan blade unit and bearing with lubricant oil or turbine oil. Rotate the fan by hand and spray again. Do this several times and wait 10 minutes. Turn the fan on to see if this works.
Remove the grill, the blades, and the motor housing from the fan. Inspect the motor to ensure the two electrical wires are secured to the contacts on the motor. If the wires are loose or broken, you will need to reattach them. To do this strip 1/2-inch of insulation from the ends of the wires and then twist the strands and wrap hem to the contacts.
Verify Cord Integrity
Intermittent or total fan failure can be caused by a pinched or damaged cord. Inspect the cord for lesions or damage of any kind. If the cord is damaged it needs to be replaced. If no damage is found, plug the fan into a functioning electrical outlet, turn on the fan and listen for the motor. If the motor doesn’t make any noise the fan is likely not receiving power and the fuse plug at the end of the cord may need to be replaced.
Appliance Won’t Oscillate
Your fan will not oscillate side-to-side
Stuck or Broken Oscillation Knob
The oscillation knob is located on top of the motor housing. Pushing this knob engages the oscillation assembly causing the fan to move side-to-side. Pulling the knob disengages the assembly and stops the oscillation. If the knob assembly breaks it will prevent any motion. Inspect the knob by removing the fan cage, blades, and motor housing. Turn the fan off and unplug it before removing any components.Ensure the knob assembly makes contact with the internal parts and nothing has broken off or is obstructed by foreign material. If the oscillation knob is compromised proceed to the oscillation knob replacement guide.
Broken Knob Insert
The knob insert attaches to the bottom of the oscillation knob. It has two ball bearings that push out and engage the core gear of the oscillation assembly. Remove the the fan cage, blades, and motor housing. Remove and inspect the insert (including the ball bearings and spring), and gear for corrosion and wear. Ensure the spring still has the ability to push out the ball bearings.
Worn Down Gears
The core gear is the component of the oscillation assembly that directly engages with the threaded end of the gear rod. Remove the the fan cage, blades, and motor housing to inspect the integrity of this gear. Check the gear for obstruction and make sure the teeth are not worn down. If the oscillation gear is damaged replace it.
Inspect Pivot Point
The pivot point is the joint the fan head pivots on. Make sure the pivot point is properly cleaned and lubricated with household lubricant oil or turbine oil. It should be free of debris, dust build up, and rust.
Make sure the cord is not wrapped around the pivot point, inhibiting oscillation.
