Hello,

My Bryant furnace model 373lav won't turn-on. At first, I can see the one of the stick in front of the burner glowed red followed with the hissing sound of the gas turned on, but nothing happened after that-the furnace did this 3 times and the burner never came on.

* Filter is clean
* My furnace was service back in June, 2009-everything looked clean.

I've reset the interlock located at the panel several times and now nothing happened when I turned on the heater. No glowing stick, no gas hissing sound and the LED stayed solid red.

Please help!

Got it fixed! Found out the furnace gave me an error codes 14 and 34. The flame sensor looked clean, but clean it using sandpapers and that fixed it.
