Furnace help please

furnace works fine this spring. Today, not so much. today I get fan on. Igniter spark but no burner. It tries to light 3 times then shuts down. Nothing visible to check or clean without removal. There is an inspection window on top but the bottom of the fridge is 3'' above. All I can see is full removal inspect and some sort of cleaning. this is a 2002. I'm guessing it's never been removed. Suburban. model unknown. Stove and
wh working fine.

Any help?

Do you have propane at other appliances?


If first time in awhile using furnace then propane system may just need to have flow/pressure established.
Light off ALL stove top burners on high and let them burn
Then try furnace again......might take several attempts to get propane flow to furnace


If furnace worked and then not....probably will have to pull it and do a burner clean up and combustion/exhaust chamber sweep
Sparking proves DC is getting to circuit board OK.

You were correct Biscuit. the DW went to the store and I was able to play with the propane without interference. left the 3 burners on for about five min while trying the furnace. Finally came on. working fine. I thought this was gonna cut our stay short. 45 degrees this am when I got up.

Use a small mirror.

You sly fox, had the same thing with hot water, tip of the hat sir.

Then question for you, is 3 tries then default off an industry standard across all devices?
