Why does carbon monoxide only come back into the home some of the time?

Chimneys do not work as well when they are cold than when the weather is warmer. (That whole "warm air rises" and "chimneys are cold in winter" facts of physics) Also with the installation of higher efficiency furnaces that use fans to exhaust eh fumes in the furnace, these furnaces will draw fumes back from a hot water tank or clothes dryer into the home when the furnace is working

Can my gas dryer or may gas “ventless” fireplace or space heater vent CO back into the home?

Your dryer can vent back into the home. A blocked vent with lint is one cause. As mentioned above, a furnace with a direct vent system can pull the fumes back into the home
