Tis the season to fire up the ol' wall heater; brrrrrrrh, I could have used it last evening. In the past couple years at start up in the fall, I light the pilot light and when turning the gas knob further to its operational position, the pilot light goes out. A few more tries and I finally get it going, BUT, then the unit will completely go out after a few minutes after operation. This usually happens a few times where I re-light everything and it will work for the entire winter no problem.

Last year I replace the thermo-cupler (sp?) thinking this was the problem, but no, the same problem happened where I finally got the unit working. This year, however, I'm having even more problem getting the pilot to stay on when turning the knob to its operational position to fire the whole unit up.

Any suggestions? This unit is about ten years old and even though I've had this problem the last couple/few years, it tends to run fine once I get it going. Thanks in advance.

While the pilot is on (While your holding the button) observe the flame. It should be shooting over to the thermocouple heating the top third of the rod. If this is not the case try cleaning the pilot light with compressed (non flamable) air. If this doesn't work and you have good flame contact your probably looking at another thermocouple or pilot safety (most likely incorporated into valve)
