My heater seems like it runs constantly, the first night it came on &amp; off automatically. Not sure why it's not still working that way?

My American Comfort did the same thing, so I returned it to American Comfort in Canada. I believe there was a phone number on the box. I got a brand new unit which has worked perfectly. Excellent customer service. Just gotta get in touch with them.

So far the heater does not turn off by itself. There is a red light the glows to show power is on.

I had a heater like yours and it did not run it. I was so disappointed with the unit, I sent it back and received a refund. BTW, it's made in China.

hello after installing the heater my car sat 12 hours and i had to jump it to get it started so i add a on/off switch to kill the power to the unit when the car isnt running have not had a problem with it sence, other than it doenst put out enought heat

did you turn up the dial to maximum heating temp?.sometimes it gets turned down by error. IF it is all the way up...check the electric going to the heater...(that it is on) IF good..they it burned out....get a new one...

I had the same problem. I first replaced the over protection switch and the hi limit switch. heater then came on and as you have it just ran hot even in air dry, so I replaced the thermostat and the heater still remain hot and brightly glowing. I talked to a repairman and he said to check the heater for a short to ground. It was shorted. Replaced the element that only had one of the ceramic element holders broke. This fixed my problem. I hope this helps.

I'll try to help. The heater has two modes. Either it is on for a pre-set time or it has a thermostat which determines when it is on based on the temperature of the room. When you set the thermostat it will initially show the temperature it is set to and then go to the current temperature. In this case it sounds like the heater is not turning on because it is set to maintain a temperature of 73 and it is already 77 in the room. The thermostat is on the heater so if the room is cold but the heater is in a relatively warm location (say in direct sunlight) then the thermostat will be fooled and you won't get it to perform the way you want. I put the heater in a relatively cold spot in the room and away from the sun and other heat sources. I hope this helps.

The only thing I can think of is incorrect wiring or you have it hooked up to something that is trying to draw more amperage than the unit can handle and it's tripping rather than switching anything on. Perhaps it's a protection circuit? Have you tried hooking it up to something that draws lower power? I had mine wired to a heating pad as a warming pad for a while to start seedlings. Then I wired it into a home made aquarium type heater. I don't get any 'alarms', my unit works perfectly every time. I'd have to see how you wired it and what it's wire to in order to help. Sorry.

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!!

My heater does the same.I had two since the first broke. I think their thermostats just dont work well.

I have not had a problem with mine but definitely call the company and explain to them what has happened. Be firm but not rude in letting them know that you are not satisfied with the performance of the heater. I am sure they will do something to rectify the problem. Good luck.

I found I had to set the temperature a few degrees higher for it to come on. I believe this is because the sensor/antenna is close to the wall. I am trying to remember how the programming works. I just have mine set at 72 round the clock. I will check when back home. But I love this unit! Nice steady heat and electric bill did not go up.

Is the compressor running or just the fan/coil unit after the temperature is reached? Does it cut off after a couple of minutes? If it just keeps running, it sounds like it might have been wired incorrectly, assuming the "Fan" switch isn't in the "On" position (if it is, switch it to the "Auto" position). If it just continues to run for a couple of minutes, I think the thermostat is likely programmed to do that as a (mildly misguided) effort at efficiency by taking advantage of the low refrigerant temperature that lingers a bit after the compressor has shut off. I actually don't have this model (and am not sure why Amazon thinks I do), and I am going from the behavior of the model TX5000Ua that I do have.

Rob- Sorry, But Can't Help You. I Purchased the Heater About a Year ago and Have Given it to a Good Friend. Myself, After trying the Heater Out, I Was "VERY EMPRESSED" !!!. It was the Best Heater We Found, to Heat My Friends Garage, for Our Weekly Card Game. Hope It Helps ? Take care Ken

These t-stats are only rated to run a single heater. You could be overloading it. Try unhooking one and see if the noise goes away

I did a test with my Lasko full circle heater layed it on its side and it still ran. I even let it fall about one inch from the floor and it did not stop running, I let it stay there about a minute. So as far as my heater goes it did not stop running. Other then that I really like it. I hope this helps you out. Have fun !!!

Is it possible you did a temperature over ride by accident? That will trump the scheduled temperature and make the furnace run until the rooms temperature adjusts, or until the next scheduled temperature takes effect. The only thing other than that I can think of is maybe the wiring is wrong?
