last night a toilet overflowed on the 2nd floor causing water to run down into the laundry/furnace room . . . since then then furnace will try three times to ignite and stop. It's a carrier weather maker 8000.

I've turned the gas and power off to the unit and let it sit for over 5 minutes, when I turn it back on, the (glow light) turns red and the four gas burners kick on, but only for a few seconds . . . it repeats the process 3 times and stops.

It's now only 50 in my house and we're in single digits outside . . . PLEASE ANY HELP!!
