I just replaced the draft inducer motor/fan. the old one was screeching and difficult to spin.
After replacing the part, the draft inducer starts, and the ignition occurs, but before the blower motor comes on, burners turn off and back on but not all the way on. The draft inducer seems to either be told to stop or is having issues running. It slows down (it is not variable speed) and it continues to try to run for 1-2 minutes until finally the entire system turns off and flashes a code for a soft lockout (max trials for ignition reached)
When the draft inducer first experienced problems it seemed as though it was experiencing a suction blockage, but I can't find any blockage. It also sounds as if there is paper in the inducer fan. I have taken it apart several times and there is no water and no debris.
I would also note that when I install the inducer motor, it is easy to spin by hand, but every time it runs and turns off, it is very difficult to turn until I remove it from the furnace at which point it spins freely again. Please help!
