Sooner or later, you’ll encounter a problem with your furnace. Once your heater malfunctions, it’s important to know when to call a professional for help. A tripped circuit breaker or an incorrectly set thermostat are things you can remedy yourself, but many more issues require expert furnace repair services.

Malfunctioning Blower Components

Your furnace’s blower is responsible for circulating the heated air throughout your ductwork to keep your home comfortable. It’s made up of several components, including a motor and a fan. If the blower isn’t functioning properly, the warm air won’t reach all of your living spaces. You’ll need a technician to inspect your blower bearings, belt, and capacitor if you’re experiencing problems.

Faulty Starter

Every furnace has a mechanism that starts the heating cycle. Older ones typically have a pilot light, while newer versions use electrical ignitions. If your starter is malfunctioning, the furnace won’t turn on. Regardless of which type of starter your heater has, you’ll need to have it repaired or replaced if it stops working.

Heat Exchanger Malfunctions

The heat exchanger encompasses a coil of heated tubes. It plays an important role when it comes to heating the air. Without routine maintenance, the heat exchanger can crack or malfunction. You’ll know when this happens because you’ll notice lukewarm air coming from your vents.

Broken Limit Switch

The limit switch ensures efficiency while preventing possible hazards. It detects your furnace’s internal temperature, which allows it to activate or deactivate the blower fan. If the internal temperature reaches a dangerous level, it shuts off the burners. This prevents fires and serious damage. If your limit switch is malfunctioning, your furnace will continuously run.

Malfunctioning Thermostat

Your thermostat detects the temperature in your home and relays that information to the furnace, which initiates the heat cycle. When your thermostat malfunctions, it incorrectly reads the room temperature. This causes the furnace to either run when it isn’t necessary or not cycle often enough to keep you warm. A technician can inspect your thermostat and diagnose any problems with the hardware or software.

Gas Leaks

You’ll notice a slight burning odor when your furnace first comes on after not being used for quite some time. This is a normal occurrence caused by the dust within the heating system burning off. It doesn’t last long. However, if you notice the smell of gas, immediately turn off the gas valve and call a professional for help.
