Heater keeps shutting off !!
I have model 5532, but I think they all have the same problem. There seems to be a safety device in the ceramic heater that turns off if it gets too hot. It "remembers" when this happens as well and will shut off until it is unplugged for 10-15 minutes.
This happens on even lightly used heaters if used in dusty conditions. Dust builds up behind the ceramic heater and the lack of flow causes it to overheat. The unit must be dismantled and the dust brushed/vacuumed out. The good news is that not only will the heater work again, but it will have better airflow too!
To do this, tech support and other people say to "clean the rear grill", but my rear was not dirty. The front grill had some dust that I vacuumed clean, but did not help. In my unit there are no filters before the air goes through the heater element. The problem is in the center of the heater. Taking out the internal fan (four screws on the sides of the squirrel fan box), I could see that the radiator was over half covered in dust. I cleaned that dust out using a shop vac and the problem went away.
Opening the heater was a little tricky, two of the screws were triangle head screws. Once inside, however, it is a simple proceedure to remove the fan. Of course, you should unplug the heater and wait a while before opening it up to make sure there are no electrical charges stored in the unit.

I am currently using a Lasko 5812 heater. The problem is it keeps shutting off, especially in the high setting. How do I fix this?
1. A Tip-Over Switch is built in to prevent operation if the Heater is tipped over.2. A thermal overload protector is built in to prevent overheating.3. If an overheat temperature is reached, the Heater will automatically shut off. It can only resume operation when the user resetsthe unit.To Reset Heater:1. Unplug the Heater and wait 10 minutes for the Heater to cool down.2. After the Heater has cooled down, plug the unit into a 120V~ electrical outlet and follow the operation instructions describedin this manual.
TROUBLE SHOOTING TIPS

Portable Heater keeps turning off
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
2. Remove the heating element. These should be Phillips
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
I hope this work for you and good luck!
