Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

Hi.  I went through the troubleshooting guide and everything checks out right to the last thing listed that is No Spark....then it says to call a technician.  I replaced the ignitor a few years back with a Carlin #41000 and it been fine.  No I have NO SPARK CONDITION.  Can anything else cause this condition besides a bad ignitor?  I'm planning on buying a new one this morning.  Also, I did the "screwdriver" test across the posts of the ignitor while calling for heat.....everything acts as it should except no spark.  I lit a twited up paper bag and tossed it in the chamber then called for it and it fired and stayed lit until it blew out the flame so it has fuel.  Nozzle has been cleaned.  Good air psi and fuel psi.  Both green and yellow lights are lit when they should be.  The thermostat is working properly also.  Thanks!!
