Re: its -20C outside, and my furnace isn't kicking in. help?
does it have a thermocoupler? that's what senses the flame and tells the regulator to keep the gas flowing. Sometimes the ingnitor works as the same piece.
Last winter my ignitor needed replaced, the old one's crack easily and won't get hot.
Mine acted up again last weekend, the tube from the regulator that has gas for the pilot flame (first thing lit by the ignitor) was clogged a little, there was a small jet opening when I took it apart...
It's really easy to pull the burners out of mine, two screws and I can get it out to blow air through it. A little rust or dirt will really clog the lines. After your furnace tries to light once or twice it will go into "lockout" and you need to reset the power to it..
