Have you noticed a burning smell, odd noises, the smell of heated air coming out from the furnace or the furnace automatically shuts down without your knowledge? If yes then that’s a clear indication that the furnace is overheating. Modern furnaces are equipped with built-in features that ensure that the system automatically shuts off when it gets overheated. However, even with modern safety measures in place, the fact still remains that an overheated furnace is not good for your home. Overheating is a problem that needs to be addressed as soon as it is detected by an experienced heater repair expert because it indicates that your furnace is overstretching itself to warm your house. If you ignore correcting the problem on time then crucial parts of the furnace will be permanently damaged forcing you to spend more on the repair. Below are the reasons why
your furnace is overheating.
1. Reduced airflow
Proper airflow is crucial for normal functioning of the furnace. If the airflow is restricted, then crucial components of the furnace such as the heat exchangers will overheat. Airflow issues are mainly caused by a dirty or clogged air filter. The main function of the air filter in the furnace is to trap airborne contaminants to prevent them from clogging the ventilation system. When the air filter gets too dirty, then it impedes airflow, forcing the furnace to overwork in order to warm the house. If you have noticed that your furnace is overheating, then the first thing that you need to do is check if the air filter is clogged. If that is the case then you need to replace it with a new one. Air filters in the furnace need to be replaced at least once every month.
2. Mechanical failure
If one crucial component of the furnace has broken down, then the remaining components will be forced to work harder in order to warm the house. If other components of the furnace are overstretched, then they will automatically overheat. To prevent this, then it is important to ensure that your furnace is inspected regularly by a reputable heater service. This way, all parts that have broken down will be repaired or replaced.
3. Too dirty components
If the filter is too dirty and clogged, the chances are that the other crucial components of the furnace such as the fan, evaporator coil or the motor are also filled with dirt. If too much dirt sits on the blower fan, the heat exchanger will overheat because the blower fan is unable to cool it down. If this problem is not fixed on time, then it could lead to multiple equipment failures.
4. Short cycling
If the furnace turns off too soon once you turn it ON, then it is because of short cycling. If this happens repeatedly, then it can stress crucial components such as the blower motor or the heat exchanger forcing them to overheat and in worst case burn out completely. If your furnace is short cycling, then you need to contact a professional heater service immediately to fix the problem
