Furnace Kicks On Then Shuts Off
Furnaces are a common appliance found in many homes in colder climates. They are responsible for heating up the air in the home and keeping it at a comfortable temperature. However, when a furnace kicks on and then shuts off without completing its cycle, it can be cause for concern. This type of problem is often caused by a number of different issues, ranging from a dirty air filter to a malfunctioning thermostat. In order to determine the cause of the problem and resolve it, it is important to understand the symptoms and potential causes of a furnace that kicks on and then shuts off.
Common Causes of a Furnace Kicking On and Then Shutting Off
The most common cause of a furnace kicking on and then shutting off is a dirty air filter. The purpose of the air filter is to remove dirt, dust, and other debris from the air before it is heated and then circulated throughout the home. If the air filter is clogged or dirty, it can restrict the air flow, causing the furnace to overheat and shut off. Other common causes of a furnace turning on and then off include a malfunctioning thermostat, a malfunctioning blower motor, or a problem with the furnace’s electrical system.
How to Diagnose the Cause of a Furnace Kicking On and Then Shutting Off
In order to diagnose the cause of a furnace kicking on and then shutting off, it is important to start by checking the air filter. If the air filter is clogged or dirty, it should be replaced with a new one. If the air filter is not the cause of the problem, then it may be necessary to check the thermostat, the blower motor, and the furnace’s electrical system. If these components are found to be functioning properly, then it may be necessary to call a professional for further diagnosis.
How to Prevent Your Furnace from Kicking On and Then Shutting Off
The best way to prevent your furnace from kicking on and then shutting off is to keep the air filter clean. Air filters should be inspected and replaced at least once every three months, or more often if the furnace is running frequently. Additionally, it is important to have the furnace serviced regularly by a professional to ensure that all of the components are functioning properly.
Conclusion
When a furnace kicks on and then shuts off without completing its cycle, it can be a sign of a number of issues. In order to determine the cause of the problem and resolve it, it is important to understand the symptoms and potential causes of a furnace that kicks on and then shuts off. The most common cause of this problem is a dirty air filter, but it could also be due to a malfunctioning thermostat, blower motor, or electrical system. To prevent the problem from occurring, it is important to keep the air filter clean and have the furnace serviced regularly.
