If it stays dark, the thermostat has probably lost its 24-volt supply, often from a blown low-voltage fuse on the furnace control board.

They solve different problems. Cleaning is worth doing when there is visible debris at the registers, evidence of rodents or insects, water damage inside the system, or drywall dust left after renovation work.

A musty smell is usually neither, since it normally starts at the evaporator coil or a standing-water condensate pan.
