A broken furnace is one of the most frustrating things homeowners can face. Unfortunately, we all must 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.
#1 THERMOSTAT DOESN’T WORK
A malfunctioning thermostat is possibly due to a unit’s lousy performance. 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 adjusting it until it’s level.
Another possible culprit is a frozen anticipator if your thermostat has a mechanical component. Find the arm attached to 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.
#2 DIRTY AND CLOGGED FILTERS
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. It would be best if you changed your filters once a quarter for peak performance.
#3 FLICKERING OR WEAK PILOT LIGHTS
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.
#4 CRACKED HEAT EXCHANGER
Unfortunately, this can be costly. Your furnace will run safely if your heat exchanger separates the warm flame from the cool air. If you overheat your home 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 a complete replacement.
A Heat exchanger is the heart of the furnace. This system part is responsible for heating the air in a gas furnace. It’s made up of several tubes or coils, which continuously loop through the furnace’s airflow to heat the atmosphere. The model and type of furnace determine the shape of the coils. It would be best if you did not ignore cracked heat exchangers. Cracked heat exchanging parts can seriously threaten your home’s safety. The gases that are being burned, like carbon monoxide, sulfur dioxide, and nitrous oxide, could leak into your home and cause illness or death.
#5 MALFUNCTIONING OR FRAYED BLOWER BELT
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.
#6 FREQUENT & EXTENSIVE CYCLING
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 have a clogged filter. A furnace that cycles frequently will lead to a higher power bill.
#7 MALFUNCTION OF LIMIT SWITCH
If the limit switch isn’t working correctly, the heater might constantly be blowing even though it shouldn’t. It is necessary to have this repaired by a professional technician.
#8 FURNACE ISN’T BLOWING AIR
There are a few possible causes. It is crucial to ensure that your blower is clear. Next, look for a flashing light in your furnace. If the light is flashing red, you will likely need to call an electrician to repair the issue.
#9 BALL BEARINGS THAT ARE NOT WORKING
The unit’s roller bearings are essential for proper motor operation. Over time, however, they can wear down and 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.
#10 FURNACE MAKES RINGING OR RATTLING SOUNDS
Is there a popping, pinging, or rattling sound 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 heated or cooled.
