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 have 2 screws on this same model 6221 that will not release.. At least I am assuming they are screws one in the top corner and one in the bottom corner.

Bench test. With heater tore apart, energized, a volt meter connected across the sensor will indicate a voltage when it opens. take note of aproximate temperature and compare with the sensor temp rated value.
It takes a bit of skill to trouble shoot, repair, and put it back together. Toss it out if in doubt.

Either the Overheat switch, or perhaps the Tilt switch is shutting down the unit.

Make certain there is nothing in front of the unit.

Make certain the unit is flat on the floor.

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!
