I have a lasko ceramic heater. It was working fine one minute then I turned it off and when it got chilly again, I tried turning it on but it wouldn't even beep, let alone turn on.

Try taking a can of compressed air and spray in the vents in the front and the back of the heater. The heater has a sensor that gets dusty and causes it to shutoff to prevent overheating.

The heater should function properly once the dust is blown off the sensor.

Good luck!

mine does the same thing every year. I just clean out the dust from the vents on the back of the heater so the heater can breath otherwise it could get too hot and the safety fetcher kick in and makes the heater stop working.

Blow the dirt off the filter in the back... then shut it down for 5 min. it should then work..

SOURCE: Won't turn on. It gave me a beep when I plugged

Have you cleaned the filter that's on the back? This has happened to me, and I just took the filter out and cleaned it, and it worked fine after.

I just fixed my Stanley Lasko 675900 FOR GOOD and would like to tell the world how to fix it!

1. Remove the front plastic grill. The bolts are torx heads with a center pin. You may be able to find a torx head driver with the center pin but I improvised. I Used a dremel tool with a small rounded diamond bit to grind the center pins out of each screw so I can use a standard torx head driver on the screws.
2. Remove the heating element. These should be Phillips screws.
3. Blow out the dust from the back side of the heating element. (be careful with the fragile fins)
4. put it all back together and it should work just fine.
5. (optional at your own risk!) I believe the small gadget attached to the top of the heating element with the white wire is the limiter. You can use pliers to slide the unit out of the element and either move the unit further toward the center area, or cut the device out completely with wire cutters and then splice it back together. If you do this REMEMBER TO CLEAN THE BACK OF TH HEATING ELEMENT EVERY MONTH TO PREVENT A DUST FIRE!

I hope this work for you and good luck!
