  • Anonymous Feb 27, 2009

    Low burner stays lit for one minute and then goes out. Full tank of propane. Very frustrating! Probably the last time I buy Charmglo anything.

    Same here. I've used the heater less than a dozen times in 9 months. Now it lights but goes out after 3-5 minutes. What's up with this?

The other day our Aquastar 125 pilot went out. No problem, I relit it. It has gone out several times since then. But when I relight it, it often turns the burner on as if the faucet is running. AF

Safety valve is overheated water.
Sounds like the flow control sensor or other sensors, or pc board are bad.
You need service technician to diagnose problem and replace part.

Or replace whole thing with tank-type heater.

Pilot light burns too yellow and irritates eyes

When a pilot light turns yellowish and fumes heavily it is generally cuased by the flame not getting enough fresh oxygen. If you feel comfortable accessing your pilot light turn off the gas and allow it the heater to cool for 30 minutes. Next look for a small (1/16 diameter) hole in the side of the pilot. There may be a perminately attached metal strip in place covering it partially it this is for adjusting air flow and should not be bent or removed. Now take a bendy straw and gently blow through the hole and see if it dislodges a small bit of dust or hair. Remember gently any pressure over 30psi will damage your heaters componates. Next reassemble and relight the pilot. When it is warm and operational if it is still yellow and fuming call a repair man. Never attempt to adjust pressure or flow by yourself.

I have a Charmglow patio heater. I have taken it apart and cleaned all openings where the gas comes out, but the flame still goes out after 7-8 minutes. It lights fine but will not stay lit for more than...

From what you have described, it sounds like the Thermocouple is going bad and needs to be replaced. As far as not being able to relight the pilot right away is concerned ... that's a safety feature. The control has to reset itself, before you can relight it, if the pilot goes out on it's on. As it did in your care. It usually takes about 2 - 3 minutes for the control valve to reset itself.

As far as replacing the Thermocouple is concerned, it's somewhat of a specialty item, because of it being in a tall patio heater. However, armed with the Model # of your Charmglow Patio Heater, you can probably purchase one from the manufacturer, Chamglow.

Hope this helps.

My heater is cycling on and off it will run for a while and than the red service light comes on for about 4 or 5 minutes than it relights and runs again

Pull the lower front panel and inspect the top of the burner. If there are ashes and debris on top of the burner, especially near the ignitor, then clean it off.

In any gas heating appliance there will be a thermocouple that sense if the pilot flame is lit (lighted?).
You bypass this with the regulator by holding the button temporarily and that allows you to light the main burner. If the thermocouple is bad (not uncommon- they sit in a hot seat all the time), it will disable the gas supply.
The thermocouple should normally measure nearly zero Ohms on a multimeter; if it doesn't, it's bad.
If the thermocouple checks out OK, then the regulator has failed.

Burner on Charmglow patio heater will not stay on.

believe it or not, the propane tank may be too full. The vapor space is taken up and you have very little vapor. Run some warm water over the tank. The garden hose may be enough but if you get no frost line the water will need to be warmer. The warm water causes the liquid fuel to turn into vapor. Do not use boiling hot water. Another thing is oening the valve. Most propane tanks have safety valves. If the gas escapes faster than a normal rate, the valve closes. Open the valve slowlyand lt it burn for about 10 minutes before opening the valve further. It will get better as the fuel is used up and the vapor space in the tank increases. In real cold climates a heater blanket, sleeve is used tho keep the bottle warm. The vapor also creates the the needed pressure to move the gas through the system to the burners. Good Luck-Ned_

Outdoor patio heater won't stay lit

I'm told by Charmglow that the problem is the Thermocouple. iHowever,it took me several calls to get someone to admit this. They are sending a new thermocoupler. My heater is less than a year old and under warranty--but it's a shame things like this happen.

Originally I was told it could'nt be the thermocoupler as they normally last at least 5 years.

Try it--as it may solve your problem as well.
