Thermostat
To turn off the furnace, locate the power switch or breaker connected to the furnace and switch it off. This will shut down the furnace and stop it from running.
There is probably a thermostatic control somewhere that shuts it down when some temperature limit is reached, and on again when the temperature gets too low. Alternatively there might be a fault which shows up when the furnace gets too hot.
A furnace by definition provides heat. There must be something that controls that heat; that is that tells the furnace when to fire up the burners and when to shut down the burners. This function is provided by the furnace control system. Usually the control system itself is controlled by a thermostat which maintains the temperature at a preset level on the thermostat.
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.
To turn on a furnace without a thermostat, locate the furnace switch on or near the unit. Flip the switch to the "on" position to start the furnace. Keep in mind that without a thermostat, you won't be able to control the temperature or set a programmed schedule for the furnace to operate.

With winter upon us, the important thing in keeping your home comfortable is making sure that your furnace is in good shape. Without a decent furnace, one that works well and can hold up to any kind of endurance test you put it through in the dead of winter, you can expect to be sharing the bed with the kids every night as they try to stay warm. If you want to make sure your furnace works and keep furnace repair costs down, call your furnace services in for a tune up at the start of winter to prevent breakdowns.
A fan cooler relay in an electric furnace controls the blower motor's speed to optimize cooling efficiency. When the furnace reaches a certain temperature, the relay activates, adjusting the power supplied to the blower motor, which can either increase or decrease its speed. This modulation allows for better airflow and temperature management, ensuring that the furnace cools down effectively without overheating. By using the relay, the system can respond dynamically to temperature changes, enhancing overall performance and safety.
Every hot water heater I've seen has a regulating knob somewhere. Look for it,possibly under a cover.
To shut down a coal furnace, follow these steps: 1) Turn off the power supply to the furnace. 2) Close the air intake and exhaust dampers to restrict airflow. 3) Allow the fire to burn down and the furnace to cool before removing any remaining coal or ash. 4) Dispose of the coal ash properly and clean the furnace as needed.
Remove any stones, put the jewelry into a crucible, and the crucible into a furnace, heat until melted, pour into molds. A blowtorch would do the job as well, ideally oxy-acetylene.
