yes, the answer is easy . . . you are burning the oxygen up , and the safety is shutting down the unit . . . had my unit doing the same thing . . . thought the regulator or the pilot system was defective . . . bought a second regulator . . . only when I lit the unit outside after another shutdown , did I read the booklet and finally understand that there is an O2 sensor , that will shut the unit down when the level of O2 is dangerously low . . . I needed to essentially "open a window" to keep the unit running continuously . . . it took some time and experimentation to find the smallest opening to allow an exchange of O2 and not "give away " too much efficiency . . . yes, the answer is easy . . . you are burning the oxygen up , and the safety is shutting down the unit . . . had my unit doing the same thing . . . thought the regulator or the pilot system was defective . . . bought a second regulator . . . only when I lit the unit outside after another shutdown , did I read the booklet and finally understand that there is an O2 sensor , that will shut the unit down when the level of O2 is dangerously low . . .

The heater contains an oxygen sensor that will measures the amount of oxygen in the air. Try ventilating the space by opening windows and/or doors to get a fresh air supply in the space. Tr-light the heater and leave the doors and windows open and see if the heater shuts down again. If so, you've probably a faulty sensor. If the heater keeps going while in a fresh air environment, you need to read the instructions and provide a source of fresh air. Our heater is in a garage and I keep two windows cracked open, one on each side of the space. No problems. We added a smoke/carbon monoxide detector to also monitor the air.

My Community Center has 23 of these units and the only time we could not relite the unit was due to a faulty thermocouple. How large is the space in which you are using your unit? That may be a reason for either the CO2 buildup or thermocouple shutting the unit down. Wish I could guarantee the answers I just gave ...... good luck

It's been several months since we replaced ours, so only going on memory here. There was a 'one minute' button which would heat on high for one minute. If you enter say 530, it should heat for 5 minutes 30 seconds, at whatever power level selected. If it doesn't do that, it's defective. Try entering a time then hit the timer button, which should just time down and sound the alarm when the time is up. If that doesn't work either, you know it's defective. Good luck. (Our control panel worked fine for 10 years.)

There is a troubleshooting guide on page 6 of the owners manual. I used to work for a rental company that rented these out. It could be a number of things from a bad electrical part,a partialy plugged nozzle,bad thermostat.Try the troubleshooting first. It's not an easy thing to try to explain in emails if you don't know much about these units.Does it keep running after you restart it?

If you leave the light on then the power is going thru the unit and the heater coils will heat the water up to temp in say 10 mins or so and you could then "take your shower" ........................... if you forget to go shut it off it will continue to keep the water at the set temp and cost a lot to maintain that temp.Really if you take a shower everday at say 6am then just put the timers on to have the heater come on for 30 mins starting at 5:30am and when you hop in it will be all hot for you and you don't have to mess with it again, it will shut off at 6am and you will have hot water most of the day ...................... the main reason for buying one of these is so you don't have to mess with it???

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

I have two of these heaters and never noticed that problem. I don't think it is normal, maybe the wire got damaged. I would exchange it just in case.

happened to me too...i contacted the seller and they told me that it usually shuts down if it over-heats and should work after some time...but that never happened to mine so i returned it and got a refund...

When mine stopped working, I asked my father (who was a small applicance repairman back in the day) to look at it. He told me it's a "closed system." He couldn't get the unit open to even look at it, let alone repair or replace it. Not sure the manufacturer could help. When I called them about mine, they told me that amazon would replace the whole thing - which they didn't. Amazon told me they don't carry this heater anymore and instead, gave me a refund.

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.

wish I could help, mine is still working fine. My guess is that they are trying to find a more reliable manufacturer for these regulators. good luck

Check the red over load button on the back of the heater. Check the power supply of the outlet plugged into. If that checks out ok, it is defective and you need to return it under warranty.

Yeah had the same issue. Headed up with in 10 mins of use. The manual does mention not to use it for prolonged periods though. Mine didn't last too long after it started heating up

I have the same problem with this heater also. It shuts down after just a few minutes on high and doesn't come back on until it cools down and then you have to manually turn in back on at the lower setting. I am not going to try and fix it but I will solve any future problems with this fan by not ever buying another one and I would not recommend this fan to anyone....It is very annoying!

Good question! Let me know if you find one. This would be an excellent heater if the manufacturer did not use thermocouples that they know are defective. Why do I say that? Because nearly EVERY review that I have read States the same problem. Now I have a heater sitting out in my garage that will not light! I recommend that any person thinking of purchasing this heater buy a Mr Heater instead. They work! If World Marketing would send me a new thermocouple (that works), I would install it.

I have not had that problem with my heater. But it sounds like there may be a small clog in the line near the pilot light.

We tried everything with this heater. Even a new wick. It just doesn't work well and it is VERY smelly, as in the smell of kerosene.good luck

Try blasting the pilot light area with compressed air. If that doesn't work would test thermo-coupler. The thermo-coupler is the piece of metal surrounded by ceramic that sticks into the pilot light. Once it heats up it creates a small amount of electricity which hold open the gas safety valve so if the pilot light goes out the gas shuts off. This is why you have to press down on knob to light it you are manually holding open gas safety valve.
