BRC 10a furnace pilot light not working

Hi,

Have a 1981 pop up tent trailer with this furnace. Pilot light has been unable to come on. I have trouble shoot the gas control module and gas line seems to work all the way to the point when the gas enters the pilot assembly. At this point I have shot compressed air through the pilot orifice but can't feel any air coming out on the other side. Is the orifice dislodged or in a closed position? Pics shown via link. Lincoln

  • Its working again. Thanks for the tip on mineral spirits. It was the clogged orifice. Working pilot in pic. Follow link.

  • I had a hard time figuring out which way the knob turned at first. On ours the marker must be at the bottom (not seen) and when it says "Pilot" right side up at the bottom that is "pilot." Turn clockwise to "Off" and counter- clockwise to "On" (which lights the main burner)

    The temp control knob on ours doesn't seem to make any difference. The furnace front gets really hot. A little kid would have to learn that the hard way! You can get some heat by just leaving the pilot lit and no main burner.

    EDIT-found my old thread--see post 1/28/15 at 4:16 on cleaning the pilot orifice.

  • Can't remember exactly, but I had the whole thing apart. I found this article to be useful. Para 6 mentions getting at the pilot orifice but I can't remember if that is what I did.

    You can google for more BRC-10A stuff. I see in the official service manual it just says, "....remove orifice from pilot, clean by blowing out frontwards and backwards with high pressure air and replace."
  • I had to take mine all apart and soak everything in mineral spirits. Then the pilot orifice was able to squirt the spirits ok. There was something else going on too, where you can use your lighter to heat the thermocouple (whatever that is called) before lighting the pilot, but didn't have to once it was all working. Be sure to close the little pilot access flap door thingy as soon as you do get it lit or it won't stay lit long enough for you to go to main burner.
  • That orifice is really tiny- like .001" . Way to small to blow air through- you might try soaking it in alcohol.
