    My guesses here would be dirty air filter, open (blown) fuse on your control board, or maybe your blower motor. What brand of furnace do you have, as that could help with troubleshooting.
    In any case, first thing I'd try is changing or just removing for now your furnace filter and then shut power off for a couple minutes again to reset it. Then give it a try. Next, is your blower motor working? If it's out, the burner will trip the high limit switch. Also, check any and all fuses that you see on the control panel inside the furnace and make sure they're not blown.

    This is true. We went through this a while ago. However, it turned out to not actually be a dirty flame sensor, but a faulty circuit board that made it act like a dirty flame sensor. Those guys were so sick of coming out here.

    Glad to hear you at least have some heat Joe.

    All good advice. I hate to say it, but if it is the circuit board you could be looing @ about $300 just for the replacement board - not counting "service" fees.

    Check the vents, filter, clean the sensor, and try just running your "fan" (no heat - usually has a setting on your thermostat for this) to see if that is working properly.

    The flame sensors really should be taken out and steel wooled/fine sandpapered about once a year as they do get dirty.

    I've had MANY problems with my furnace over the last few years and it was always either the flame sensor, the ignitor (went out twice), or the circuit board (that one hurt bad).

    well guys, I made it through the night without freezing

    The bedroom stayed 66 degrees with the gas fireplace and the rest of the house only fell to 54

    last night I cleaned the probe, changed the filter, checked all vents and reset the furnace a few times.

    The furnace lights and blows for about 30 seconds and then I get an error message for "Inducer Motor" and after 3 or 4 attempts I get the high limit error

    I guess today I'll call a pro

    Too cold for this man...I had -10F at my place this morning...ughh... I chased a flame sensor issue myself ~2 weeks ago, PITA. My advice, pull-out the Installation Instructions manual and use the Troubleshooting Flowchart. More than adequate to get you to the field-replaceable unit level (part) or a source / fault problem (sensor limit or fail, AC/DC/Amps/ground, etc.). Pretty simple shit...just use common safety practices and common-sense re: power & gas. The down-side, if parts are required you have the "lag" to order/get them on-site.

    I did some digging, and found some similar instances of that error code that turned out to be either the inducer motor or the inducer motor control board. It seems some brand(s) had older setups that used a separate motor and control board, and newer units have the control board built in to the motor. Just a thought as to where to start.
