I have a charmglow patio heater, Its about 3 to 4 years old. I used it last march, 09
i put in a new tank i could get the pilot lite lit, but not the burner. i then thought it was the regulator and changed that. Nothing, i then changed to another tank same problem
Hello Diaquinta! I believe that since it's been several years since you last used the heater, you should clean out the venturi tube and the burner. Most of the time what happens is insects and spiders get into the burner venturi (tube) and build their little nests and such, and that will block the gas flow from getting into the burner.
Also, since it's been 3-4 years, suface rust could also be the issue. You can use an air compressor and a wire pipe cleaner to get into all the small openings to clear any obstructions in the supply tube (venturi) and the burner itself.
Since the pilot light was able to be lit, you've eliminated the regulator as an issue. The only other thing that might be preventing the burner from lighting, is that the thermocouple may have had the wires connected to it, rust and fall off. You can remove the cover plate behind the control knob (OFF/ON, setting knob) and see if the Thermocouple has the wires attached to it. If not, you can get replacement terminals at the hardware store and restrip the wires and crimp them on.
Some thermocouples have the wires soldered to them, so for those types, you'll have to resolder the wires back onto the thermocouple to get the burner to light.
The purpose of the thermocouple is to make sure that the pilot light is still burning and lit and thus, it allows the gas to keep flowing. When the pilot flame goes out, the thermocouple will cool off and in turn, shut off the gas supply thru the valve on the patio heater.
