How do you fix a furnace that keeps running?
If your furnace keeps running, there are a few things you can do to fix it. First, check the thermostat to make sure it’s set to the desired temperature and that the fan is set to “auto.” If that doesn’t work, try replacing the air filter, as a dirty filter can cause the furnace to run continuously. If the problem persists, it may be a faulty limit switch or a malfunctioning blower motor.
In this case, it’s best to call a professional HVAC technician to diagnose and repair the issue. Regular maintenance and cleaning of your furnace can also prevent it from running continuously and prolong its lifespan.

What causes a furnace to not stop running?
A major cause of a furnace that runs constantly is a clogged or dirty furnace filter. The filter accumulates dust and other particles that obstruct the airflow, leading to overheating. As a result, the fan continues to run in an attempt to cool down the system. It is crucial to regularly replace or clean the furnace filter to prevent this issue and ensure the proper functioning of the furnace.
How long is too long for a furnace to run?
When it comes to routine furnace cycles and how often the heater runs, there are a few things to consider. Generally, running for 10 to 15 minutes per cycle is considered acceptable.

However, even running every seven or eight minutes may not be a problem, as there could be other factors at play that lead to more frequent cycling.
Ultimately, it’s important to pay attention to your furnace’s behavior and consult with a professional if you have concerns about its performance.
Why is my furnace running without a thermostat?
“`While it is true that your furnace can function without a thermostat, having one can greatly improve its efficiency. A thermostat is a device that helps regulate the temperature in your home by turning the furnace on and off as needed. This not only helps maintain a comfortable temperature, but it can also save you money on your energy bills. However, it’s important to note that the type of fuel used for your heating system can also affect how often the furnace turns on and off.
