Re: Flame stays on but only a few seconds by Keith
Post New Message Hi Glenn, if this is the first run of the season, the first thing I would check is for blockage/bug nests in the exhaust tube and burner chamber. This is common if a unit sits all summer without using the furnace. Make sure the furnace is getting between 11 and 14.5 volts and the motor is running at full speed to keep the sail switch engaged. Next I would clean the contacts on the circuit board and blow out any lint in the plug. If it still fails, take the board to an RV shop and have it tested. This shouldn't cost if it's a decent shop. Other causes could be the electrode is out of adjustment or defective, low LP pressure, or defective/holy burner chamber. It's easier to troubleshoot there than from here..... good luck
