- Using Wrong Thermostat Setting in the Furnace
Before getting to the conclusion of any problem, one must start from the basics. The owners should, firstly, see the setting of the fan. If the fan is not in ‘auto’ mode, owners must change the settings. Then the search should proceed further to the setting of the thermostat.
After setting the thermostat to ‘auto’, adjust the temperature lower than the room temperature. This will allow the furnace system to shut down. The thermostat will stop calling for additional heat. Now, wait for some time, and see if the furnace fan shuts off.
If the fan shuts down, that means the problem is solved. It also means that the furnace was constantly delivering heat to the house. Another factor of consideration is the cold weather. Generally, the furnace needs to run non-stop to keep your home warm, or you might have set the temperature too high, making the furnace-fan run constantly.
- The Problem with the Fan Limit Switch
Many people are not familiar with the fan limit switch in their furnace. Fan limit switch serves as a safety tool. It will automatically turn off the burner if the temperature gets too high. Sometimes it is the limit switch that gets set to manual override. Or the switch itself is faulty and needs replacement.

Now, if the furnace fan still keeps on running, it requires repair. The problem may be due to some faulty parts of the furnace. In such cases, the repair is the best option. Also, consumers can go for furnace replacement in such cases. Replacing the furnace with a completely new set is the best option here.
