Please help. My furnace will come on when it is supposed to, glow plug will glow, then after a few seconds the burners will come on, but they will not stay on. They fire up for about five seconds then shout down. This will cycle a couple of time then the furnace then just totally quits. Ant ideas?

Thanks

Check the air intake and output if you had snow, Mine were all iced up while your out there check the sewer vent if you have that also.. just a thought

The firing and going off in a few seconds usually means the flame detector. You can find a better description of checking and cleaning it than I can give in the sticky at the top of heating forum. Click on heating and air conditioning at the top of the page, and then the sticky. Post back if you still need more help.
