HECHICKEN,
The odds are the FLAME SENSOR needs cleaned or is bad, or the flames are not igniting and getting to the flame sensor heated up. Is there a code? A certain number of flashes? What brand is it?
Here's how it works, the igniter lights the gas and each port should light in a certain order, then when the final flame at the opposite end of the ignitor heats up the FLAME SENSOR it should be fine. BUT if the flames don't make it to the FLAME SENSOR it will try again if it fails 3 times it will shut off the gas valve. OFten the Flame Sensor get what I'd call a glaze on it, cleaning it will put you back in business. The FLAME SENSOR is an important safety sensor, usually looks like a long nail with a wire going to it. If the flames are not going to each hole, they may be sooted up if the propane tank got low, could be dust, cleaning the tubes is more complicated and a gross mess if it's black and sooted up and you might want to call someone to clean it and check the pressures and orfices if the FLAME SENSOR isn't the problem. Turn it to EMERGENCY heat on the thermostate to check to see if it's lighting all of the tubes. Flame Senors are not expensive.
Hey I found a video on YOU TUBE that will be better than me explaining. Picture is worth a thousands words. Don't use sand paper on a flame sensor, use seel wool. Avoid touching the ignitor some are fragile.
Good luck and please be careful!
