Question about Lasko 5350 Heater

Open Question

My Lasko Model 5350 ceramic space heater turns off just minutes after it is turned on. The only way I can get it to turn back on is to unplug it for about 15 minutes and then, when I turn it back on, it turns off again after a minute or so. Can this be fixed?

    Same thing here. I took it back. My best guess is the safety device that keeps it from overheating is faulty. My last Holmes did the same thing. I wish they'd remove all the safety features -- I'll turn it off when I'm warm. And for all the stupid people for whom the safety feature was designed -- let them burn up for Darwin!

SOURCE: 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 had the same problem with mine,, I called the 800# and they told me to either vacuum it out weekly or use a hair dryer to blow out the vents, both solutions seemed to have work for me ~ good luck

SOURCE: lasko5840

The 5840 has a problem with dust getting on the heater element and turning itself off after 2 minutes running. HERE IS THE FIX. Unplug the unit from the AC outlet, Then using a can of dusting air ( the kind you use to clean a computer key board) aim the compressed air INTO the middle louver of the upper adjustable heater vent and blow out the dust that has gotten on the heater element. ( You are actually blowing into the unit, clearing off the lint/dust that has gotten on the backside of the heater element that you can not see without openning the entire case).You can see the front of the heater element inside the louvers, It's the shinny metal part that looks like a small radiator.It sits behind the middle louver. After blowing out the dust, shake the entire unit to allow the dust to settle to the bottom of the case. Using a vacum cleaner try to vacum out any dust from the LOWER FRONT intake. Once the dust has been blown OFF the heater element, the unit will work just as new and not shut itself down!

SOURCE: I have a lasko tower ceramic heater that keeps shutting down.

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.

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.

Turn temperature setting all the way up.

I have a Lasko Model 5532 electric heater. It has suddenly started shutting off often. I run it through the reset procedure (unplug 5-10 minutes, then restart) and that gets it going again, but then it...


All of these space heaters have thermal protection units in them. They are safety that shuts the unit down if it starts to overheat.If your fan is operating, then it sounds like the thermal protection circuit is faulty, and you'll need to contact Lasko for a replacement. These units do not have parts that can be purchased due to their UL compliance. Check the fan though, it might be obstructed. I have seen that more than once....Rob
