It's a Comfortmaker C9MPD100J14C. The thermostat is a Honeywell RTH230B.

I think it may be my thermostat failing. This morning, after waking and turning up the thermostat setting to 67, the furnace went through three cycles--of course, with the draft inducer never seeming to turn off. So, I went to the thermostat. It read a room temp of 68, meaning that it should have been waiting for the room to drop temp before kicking on the thermostat. I dropped the setting to 66. The inducer stopped. The room temp returned to the screen as 70.

Side question: Should I lubricate / grease my draft inducer motor?

As it turns out, there was no debris. I cut the power to the furnace, removed the panel, and removed the draft inducer. It is responsible for the whine. I don't know if it can/should be oiled or if the bearing is failing slowly. The rumbling, however, was coming from the exhaust end of the draft inducer where there was a loose bracket.
