If your fan sudden stops working. It may be as simple as the plug itself Here is why. If your plug has Patent written between the prongs, It likely has a hidden fuse inside the plug..... Here is what is hidden inside the blue molded plastic plug... An online fuse with very small limited - 2.5A which means the manufacturer did not want more current than this going into the fan PC board because I guess they didn't design it to handle more though they apparently also allow more to be "drawn" into the unit at least momentarily and then you have a paper weight for a fan because the manufacturer did not create a way to change the fuse..... as you can see in the torn apart plug in these pictures. The fuse is permanently molded into the plug with no provision for knowing if the fuse "blew" or replacing it. ( Very poor desgin from my POV ). The Fuse details: See Patent if you are interested in what I am talking about. The above answer about replacement the plug worked for me on a different Lasko fan.[documento:...

The tolerances on that grill are amazing. I had the same problem and the same solution works: Pull Up on the Grill - I used tweezers and pulled up seting that grill into the groove. My eyes are not good enough to even see the groove but it must be there as I could not get the second grill dog ear into the impression ( right and left ) until I did this pull up exercise.... And don't be afraid of applying a bit of force to get this thing in place. My procedure after a dozen failures to get the last screw in ( four screws involved ) Put one of the left or right short T-6 screws in one of the dog ear tabs but do not totally tighten it down. Then screw in both of the long T-6 screws used to attach the HDD/SSD to the grill. Now use the upward pressure to giggle the grill into the slot until the final unscrewed dog ear tab is nicely centered its impression. Stop and 'Jump for Joy' :-) FInally, put in the last T-6 screw and tighten all of the screws. And one more think: thank and curse Apple for such amazing...
