Most control boards to run the fan continuously .. Although the concept is open if the fan is warm, but not rotated to rotate slowly and loudly, then maybe the blower motor is bad, which show the border .... Limted return possible, if not bad, but not yet the question of the fan .... even a small chance to implement the capacitor is bad for the engine and the motor is a good thing if you have a new capacitor, but this is .... rare, is likely to be called a contract, are not typical "do it yourself repairs ,,,,,,,
The end of the race more of a manual reset, which means that you must press the call button on it. The odds are somewhere on the fan blade fan box, or fitted with a fence. The limit switch is open, if it could not move enough air through the heat exchanger and a fire. Fan failure can slip V-belt. If the fan motor was not hot, and convert to verify that the motor is probably defective and needs to be replaced. Replace the capacitor run with him. Could just a bad capacitor. If it's just a bad capacitor, you can not change an engine, but he will replace it with an equal or higher qualification.
The end of the race, if their actions the airflow is not sufficient, so that the temperature in the furnace to be very high.
It is adjustable, works on the principle of the thermocouple.
Hopefully it will be restored in a few minutes.
But sometimes not reset itself, then you need to change.
It's really easy to change, are among others, two screws and two of her son.
Even more important is what was the motive for the opening.
These include:
Fan motor broken
Dirty air filter
dirty evaporator coil in drive A / C
something that blocks the entry
Shops are also closed
-Something else that the restriction of air causes
Good luck!
