Make certain the date and time is appropriate on electronic or programmable models - the system might be on a timer.

By hand check the breaker. Flip it back and forth.
Ensure it is remaining in the "On" position.

The heater is not producing adequate heat. Examine and alter a clogged up filter.
A furnace that has a hard time to produce heat is a various matter from one that has somehow stopped working.
In the case of a poor-performing heater that doesnt warm the house adequately first ensure that the air filter is tidy and in good condition if not brand-new.

In addition to increasing your energy expense the decreased air circulation through your heating and cooling system can cause your heat exchanger to get too hot and shut down too rapidly.
Filters clean up the air headed into the furnace and the heated air sent out back into the home. A dirty stopped up filter limits the airflow eventually causing heat and pressure to develop in the heater.
Newer more efficient furnaces are sensitive to the problem and will often shut down prior to an unclean filter triggers more problem. For other systems the heating system will continue to run however with less heat output and minimized efficiency.
