Where is the switch to the furnace to shut blower off?
There is a switch, activated when you open the service panel, that kills most power to the unit, including the DI Blower motor. Your furnace should also be equipped with an exterior kill switch, or there's always the good old breaker box. Good Luck!
Gas central heater
The "mother board" or integrated control module is essentially the brain that controls the sequence of operation in your gas fired furnace. It is located, generally, in the blower compartment. That is the bottom of the two compartments of the in the furnace. It looks like a circuit board with all the wires of the furnace leading to it.

filter may not be in correctly. if it is gas, check the pilot, if it doesn't have a pilot, it may be the ignitor. depending on how new your furnace is, it may have a safety feature that won't let it start for some reason. seeing that it will at least start the cycle is a good sign. it may be the filter not placed right. i'm not a furnace expert, just know my experiences. you may want to look at the limit switches as well, they only require a tester to see if they are good. if you own the testers, you probably know what you're looking for.
