Motor Quality: Motor size is the key to quality. Over time, it is not uncommon for smaller motors to develop sounds that are irreparable. Below are a few tips that may help determine if that is the case.
Switching: The use of a dimmer or rheostat wall control on the motor will cause any ceiling fan to “Hum”. Ceiling Fan motors need to be run from a switch that has set speeds.
Mounting: Anything not tightened properly may result in amplifying any sounds the ceiling fan may produce. Make sure all screws and light fixture glass are tight.
Wobbling or Shaking
It is considered “Normal” to have a small bit of motion in any Ceiling Fan running on high speed. Blade balancing kits included with most ceiling fans, can reduce or eliminate this motion. Below are a few tips if the ceiling fan wobbles excessively. The easiest test for loose or poor mounting; Give the bottom of the ceiling fan a light push with your finger. On stem mount fans it should come back to center and stop. If the fan keeps moving, follow these tips for excessive motion.
Mounting: The electrical box in the ceiling needs to be metal, and securely mounted to a joist or brace kit. The mounting bracket from the ceiling fan must be tight to the electrical box.Down rod or Stem: On ceiling fans with a down rod or stem. Make sure the groove on the ball at the top of the stem is aligned with the notch on the mounting bracket. There are usually multiple set screws to tighten at the ball and where the stem mounts into the top of the ceiling fan.
Blades: Ceiling Fan blades are matched sets, weighted within a gram of each other. Loose or warped blades can be a cause of wobble. Make sure all screws holding the blades to the irons, and the blade assembly to the motor a tightened properly. To determine if you have a warped blade or bent blade iron: Use a ruler to measure from the tip of the blade to the ceiling. Let the blades pass by the ruler to see if one or more are higher or lower than the rest. There can be a slight difference in height that will not cause wobble issues.
Wiring: Make sure there is power to the ceiling fan and the wall switch is in the “On” position. Follow the wiring instructions included with the fan and double check connections.
Switch housing: The switch housing is the bottom portion of the ceiling fan where the light is attached. Move reverse switch to one side or the other (stuck in the middle makes fan inoperable). Make sure any plug connections are properly inserted. Check either side of plug connections for any wires that are loose or pushed out of the plug.
Wall Switch: When using a wall switch make sure the pull chain on the motor is set to the highest speed.
Smell or Odor: Ceiling fans that give off a bad smell, typically need a new capacitor. Call us for identification.
Remote systems: Make sure the receiver and transmitter are set to the same frequency, and wired according to the instructions. Call us with model number for identification of replacement parts.
