Problem with a Lasko 3440 Floor/Box Fan.

LASKO Five Function Space Heater Fan REMOTE CONTROL LAS001 FREE SHIP

Unplug it. Carefully take off the grill and use a vacuum and/ or a damp cloth to clean the blades etc. Do not soak with water. Just a DAMP cloth on the blades only!!!!

The fan uses security fasteners to prevent dis-assembly. To clean the fan, disconnect power from fan and use compressed air to remove dust.

Take it back to Wal-Mart and get a different one.

Unfortunately, probably not. The motor would only be designed to handle 110v, and it would burn up with 240v applied. You can take it apart and inspect it, hoping maybe for a bad switch, but chances are the motor is, as you say, blown. Sorry to have to relay the bad news.

same thing with my lasko box fan awful oil smell

Replace Fan, order part from Lasko

On the back of the fan there are 6 recessed phillips head screws around the circumfrence of the fan. You must use a longer screwdriver as the screws are set in a couple of inches.

The two screws on the bottom are a little harder to see.

There are also two clips on the sides front cover. Squeeze on the sides gently to release these.

I have one of these. It sounds like you have it on breeze (the 3 wavy lines on the remote) Push that button, then push the run button(first button on the right bottom) for it to run normally. The circle with the blades in the middle(left button on bottom row) will turn the fan from low (1) to (3) high. The icons are the same on the remote and the fan itself. Hope this helps.
