It does sound like a bad blower motor but the power that is supplied to the motor comes from a solid state control board which could be the problem.

try cleaning the flame sensor .

What is the model number? I have an SLP98 (installed on 11/29/2011).... and if I take the cover off the front of the furnace the panel that has the fancy "Lennox" badge on it) you will see two clear round windows about the size of a half dollar (one high on the furnace box and one lower on the blower box.) If you look downward into the window on the blower box you can see a red LED display that will sometimes flash error codes like E228 (one character at a time). If your model has something like this, let me know. I've done some DIY fixes recently out of necessity....and their easy.....and several technicians confessed they didn't know much, if anything, about the newer high effieciency Lennox gas furnaces.

double check your wiring. R terminal on the furnace will provide 24 volts to the t-stat. W terminal in the t-stat will send 24 volts back to the furnace W terminal to turn on the heat. G terminal in the t-stat will send power to the G terminal in the furnace when the t-stat is switched to fan on. Y terminal in the t-stat will send power to the Y terminal in the furnace which in turn will send 24 volts to the A/C outside. The C terminal in the furnace should be connected to the c terminal in the A/C outside as well as to the T-stat. Check the fuse again
