I have a payne furnace downflow model number PG8DAA when it is turned on the blower runs for a minute or so then nothing happens. I held in the door cut off switch and turned to inducer wheel by hand; the furnace tried to start then. The glow plug came on and ignited the flame but it shut down right away. The inducer wheel seemed to get stuck or have a hard time spinning (plus made a rubbing or grinding noise). The wheel spins freely when the furnace is off with no rubbing noise at all. (as soon as the inducer wheel started to spin by itself I did not turn it by hand anymore)

The windings in the inducer motor are going bad and needs replaced
