I have a 3 year old concord 80 plus furnace it starts up and ignites for about 10 seconds then shuts off the blower still runs this repeats for about 2-3 more times then just never comes back on again until I restart. I believe it is the round spiral hot surface ignitor what do you think?

Sounds like a dirty flame sensor. Sounds like you have located the ignitor, on the opposite side from the ignitor there will be a small silver rod, most likely held in place by one screw, remove sensor and clean with sand paper or wire brush, reinstall and let us know if it works. Be sure to shut furnace off before attempting.

Did what you said. Sensor was a little dirty. Seems to be working now. Thanks

No problem at all. Glad you got it fixed!
