A broken furnace is one of the most frustrating things homeowners can face. The unfortunate truth is that we all have to deal eventually with maintenance issues related to our heating system. Although you will need to get your furnace fixed as soon as possible, there are some things that you can do to help you avoid costly repairs.
These are the 10 most common furnace issues that you can face. Global International Home experts will help you understand.
A malfunctioning thermostat is a possible cause of unit malperformance. Your thermostat may not be working correctly if the fan is constantly on. This can cause your thermostat to overheat and make your furnace work more inefficiently. You can check this by switching the fan to auto and checking if it runs at all heat settings.
Thermostat Setting and Room Temperature Don’t Match
This problem can be caused if the thermostat parts are dirty. Follow the instructions to clean the inside. A non-digital thermostat may be off-level due to a bump. Temperature and setting issues can also occur. You can fix it by placing a carpenter’s ruler just above the device, and making adjustments until it’s level.
Another possible culprit is a frozen anticipator if your thermostat has a mechanical component. Find the arm attached at the dial. Try gently pushing it in any direction to free it. If none of these solutions work, you should consider the location of your thermostat. It might need to be moved if the thermostat is in direct sunlight, heat or drafts.
A clogged or dirty filter can affect the furnace’s ability to operate, decreasing its efficiency. A clogged filter can also cause damage to your limit switch. You should change your filters once a quarter for peak performance.
The pilot light is crucial to the furnace working properly. Your furnace may have too much carbon monoxide if it is flickering or yellow. A call to your local furnace technician should be made if your pilot light is changing.
Unfortunately, this can be costly. Your furnace will run safely if your heat exchanger separates the warm flame from the cool air. If you heat your home too much or don’t replace your filters regularly, your heat exchanger can crack. Call a furnace technician immediately if your heat suddenly stops working. This will usually require the replacement of your heat exchanger or complete replacement.
A Heat exchanger is the heart of the furnace. This part of the system is responsible for heating the air in a gas furnace. It’s made up of a number of tubes or coils, which continuously loop through the furnace’s airflow in order to heat the atmosphere. The model and type of furnace determines the shape of the coils. You should not ignore cracked heat exchangers. Cracked heat exchanging parts can pose a serious threat to your home’s safety. The gases that are being burned, like carbon monoxide, sulfur dioxide and nitrous oxide could leach into your home and cause illness or death.
Your heaters fan runs on the blower belt (commercial), which is part of the motor. They can occasionally become damaged or frayed. The unit will make a high-pitched, squealing noise while it runs. The fan’s efficiency and performance will be improved by replacing the belt.
Do you notice your equipment turning on often, sometimes after it has finished a cycle? If so, your furnace may be running at an excessive level or a clogged filter. A furnace that cycles frequently will lead to a higher power bill.
If the limit switch isn’t working correctly, the heater might be constantly blowing even though it shouldn’t. It is necessary to have this repaired by a professional technician.
There are a few possible causes. It is important to ensure that your blower does not become clogged. Next, look for a flashing light in your furnace. If the light is flashing red, it is likely that you will need to call an electrician to repair the issue.
The unit’s roller bearings are essential for proper motor operation. Over time, however, they can wear down and may need to be replaced. If your furnace is making a scraping noise, you should immediately turn it off and call a service professional to repair your furnace.
Is there a popping, pinging, or rattling sound coming from your heating equipment? You could have several problems. A loose panel on the furnace can cause rattling. The ductwork can make popping or pinging sounds. It will contract or expand depending on whether your house is being heated or cooled.
