I have a duraflame heater. It will run for about 10 min. and shuts off. It is two years old. Why?

Blocked fillter????? We has to use the vacuum to clean ours out and get into the nooks and crannies.. After that it was good to go. I also use different filters now. Went to homedepot and got a heater filter and cut to fit. Much better and it doesnt allow as much dirt to get into the system.

If you are using the remote you might want to check the timer setting. if that is not it I heater has a very good customer service department. here is the website. www.iheaterstore.com/

Either the thermostat is set to low or it may be defective. Also the heater needs some outside air or it will shut off. Good Luck!!

Mine is abut 4 years old and never has any problem until last week, it would stop working in less than a minute by itself and then restarted later. Otherwise, I love this little heater.

It should heat up your tank within a couple hours, maybe you have a faulty heater :(

I have used it by wiring in a water heater timer it works great shuts off completely when I don't want it heating and timer powers it up 1/2 hour before I want the area warmed up then the thermostat on the unit keeps it consistent from there until I have the timer set to de-energize that circuit.

I thought I had the same problem but it started going when the heater comes up to temp. It kind of does it's own thing going on then off a minute after the flame goes out. Then the flame comes on and a few minutes later the blower comes on.My basement is big (30 x 40) with 10 foot ceilings insulated and I leave the heat on #3 about an hour before going down to rehearse (musician) and the temp has come up nicely and the blower goes on and off as needed. It also could be a break in period because you will get a slight smell until you put some hours on the unit. One other hint the blower just can't be turned on but the heater must heat up then it will work. I like the unit and works as expected.

Buy a good heater next time. The one I bought lasted about one year. I heard a lot of stories about these heaters and not good stories either.

It runs for 10 minutes off for 20 back on for 10 . Does this 4 times and then turns off.

There is no automatic shut down so it keeps blowing. The heater has a small red light to indicate its functioning. The light is way too small to glow in a dark room.

I have run the heater all night. Once the temperature is set it will go on and off by itself. In fact I think I have just left it only for several days at a time. You just need to make sure you clean the filter once in a while to help the air flow. Hope this helps.

Mine has been running 24/7 for three months now and there has been no problem. It automatically shuts off when the tank is full, so you don't need a timer. It never gets hot and it is very quiet. I forget about it most of the time until I see the full light on. It works great!

Beverly, you didn't state your model or how old the unit, but one common weak link is the on/off switch may be faulty, the second primary failure mode would be the heater coil/thermostat and would generally be cheaper to buy a new one than try and fix. If you have a handyman around he should be able to check out the on/off switch.

Hello, You might try to unplug it from the wall outlet for a minute and plug it back in again. If it doesnt work try it again. If that doesnt help your control thermostat on the front panel on the unit might be defective. I never liked the Lifesmart Heaters because mine was bought defective right out of the box new. It increased my electric bill too because it ran constantly. I will never buy another one again. If you need a new thermostat control you have to take the whole unit apart. If you have some warranty left on it they might fix it at the factory if you ship it to them. My Lifesmart Heater has a help number located on the back panel or check your owners manual. I hope this helps you out.

I would contact the Lasko company. Mine has given me zero problems, but there are a lot of safety features on the heater. It will shut itself off if any of these problems arise. Sorry, that's all I can suggest.

I have had this running continuously for aweek or more at a stretch. Unless its on high heat setting, it will turn off periodically relating the heat.
