Over time, the wire that runs up the back of the fan behind the blades may come into contact with the blades, and become damaged or severed. This guide is meant to show how to repair the damage.

    • Remove the face plate.

    • Flip the fan and repeat for the 6 screws on the back. They are in the same position as the front.

    • Unscrew the screws attaching the motor/blades to the frame.

    • Unscrew the screws attaching the plastic frame to the motor.

    • The blades cannot be removed from the motor.

    "The blades cannot be removed from the motor."

    Incorrect. The moulded plastic fan blade can be removed fairly easily.


    Once the fan's plastic grills have been unscrewed and removed, grasp the round centre of the daisy-shaped fan blades and gently pull it directly away from the motor shaft. It can also be pushed off from behind, once you get it started. Note that the motor shaft has a flat edge along one side that corresponds with the shape of the hole in the plastic fan blade part. These need to be re-aligned before (gently) pushing the fan blade back on to the motor shaft when re-assembling.

    Over time, airborne particulate accumulates on the fan blades' edges and inside the unseen hollows at the back of its round centre, which faces the motor. The fan's grills also grime up, so it's good to take all the plastic parts off to clean them occasionally. I power wash them with hot water.

Any tips for replacing the "Blue Plug" fuse after it's mysteriously blown in a Lasko box fan?

https://www.amazon.com/fused-safety-Lask...

I could hillbilly wire up a new plug to minimize the wire work, but don't want to start a fire either.

I would also like to know how to replace the plug end after the non-replaceable fuse inside the plug is blown.

Gung Ho - 답글

I don't know bout you but I was able to “pop" my fan blades right off of motor. Now I'm just going to replace plug end and see if it'll work since fixing wires didn't help.

(Yep found fuse was blown. Why would they make the fuse non replaceable when they eventually blow? Wonder how many fans people have thrown out all because of a blown fuse??

Steff Lusher - 답글

So can i replace/wire on different plug?

Many fans made today are designed to last about a year or two depending how long you use it and under what conditions. Fans built 50-years ago had oil ports which allows you to periodically to oil the motor. If a fan is kept clean and lubricated regularly it will last a long time.

If you disassemble most fans and look into the bearing cup, you will see foam rubber or a small piece of felt. Older fans used felt ro fully pack the bearing cup. If you kept the felt moist with oil your fan life will increase.

Japan made fans were the best. They had oil ports. Japan then started to have their fans made in other asian countries. Then oiling became impossible. Thus the life of these fans were shortened.
