My Carrier Crusader Model- 58SSC090-JC stopped heating yesterday. I have the thermostat on 74, but the house tempereature is 62. I cleaned the flame sensor with sandpaper and now when I turn it on, the blower blows and I hear a click like an ignition, but no flame. After about a minute, the funace just stops!

Look at the ignitor for cracks etc. The ignitor might not be working to allow the gas to ignite.
