I keep my heater on 72 degrees and after several hours, on its own, it goes up to 90 degrees and then stops running. has anyone else had this problem?

I've had this problem. The safety shutoff engages when the cord gets too hot. I changed the setting from large room to medium room so that the heater draws less watts and this fixed the problem, cord no longer gets hot and heater no longer shuts off. For some reason, most heater manufacturers do not use a high enough gage cord for their products to be run at full power for more than a few minutes at a time.

Hello Jackie, to be honest it's a small margin for error with this heater. My heater still works and some times the temperature settings work. And when it does, it's because I have somehow lucked -up in getting it to work. Sorry, I'm sure this was of no great help; good luck

My first guess is the thermostat. (Look for the dial). If you want your heater to stay on, turn the dial up just a bit. If you want it cooler, turn the dial down. If the heater is tripping a circuit or GFI in a nearby bathroom, unplug something. Other than that, I can't help.

Mine heated my 5 gallon tank in a few hours. Something is probably wrong with it if it's been on for 48 hours. Try returning it.

Contact customer service I have heard they are very good about replacing defective units, mine is still working without any problems. I have read about complaints of heater unit failing, I'm crossing my fingers my unit is still working okay.

I took the heater to work, an 80'x 100' building. In about a half hour it was around 50, and about an hour later we had 60 plus and the would automatic shut down at preset temp.

It operates like a furnace with temperature control. It turns itself on and off as needed, depending on the room. I have not got it out yet this year, but I don't remember it turning itself off after 8 hours. that would have been a problem for me. I really do like the heater a lot. I hope it performs well this winter like it did last year. Good luck.

Hi,Mine first did that when it was first installed. The temp was set to high. I unplugged the unit and not turn it back on until the next morning and it has been great since then.

I had mine on for an hour or so, and it got hot, but did not overheat. Sorry, Wish I could help.

Mine seems to keep warm forever. After the whole 24 hours it didn't shut off. Maybe this is defective?? (though I am happy it does not shut off.)

Hi Jason, I ran the heater at 70 deg for over 2 hours...nothing to get burned with. Heaterwill shut off when you reach desired temp. Only blower will run. There is a wooden "lip"that over hangs the grate and one below it. If my kids were young I would buy this.

If you set it to 73, it should turn off when the ambient temperature is 75. The temperature you see on the display when you're not adjusting it is supposed to be the room temperature. I do know from personal experience that this heater has a lot of problems and is not one that I would buy again.

Not sure, my heater works as instructions indicate. I would unplug it and let it sit for awhile. The button at the top takes a firm press, the heat indicator will cycle higher and higher and then all the way back to cold after many presses. Disconnecting the power for awhile should reset it to default 78 degrees. Mine is a 25 watt heater, so it will only heat a small tank that is in a room not overly cold. Good luck!

I sent it back, it didn't work well at all! I tried for several days to adjust the high and low temperature settings, but when then heater was on it wouldn't shut off and it would overshoot and when it was off, it wouldn't turn back on. I had it in a 10 gallon tank. UL....??

You need to make sure you shut it off at the switch. It seems to cycle the heater briefly on an off until the switch is off.
