My charmglow patio heater has been working great for all of last year... but this week end it went out and would not light...the tank was still half full
but I changed it anyway...the pilot light will lite but as soon as I let off the knob it will go out...the pilot light is burning a very yellow flame that it has not done before...tapped on the regulator and the heater worked for about 2 minutes....help...I love my heater....
Could be the gas pressure regulator.

Well, I just went out this morning and worked on the heater after it would not light last night. Turns out that a spider or moth set up camp in the pilot light intake housing and plugged up the two small mixer holes that pull in air for the pilot light. This would explain the 'yellow-flame'. I took a punch awl and some compressed air and cleaned out the hole, then re-installed the cover and knob. Lastly, I turned and depressed the knob and the pilot light ignited almost instantly, stayed on when I let the knob up, and the heater turned on normally after that. Good luck, I hope this helps.
