The heater in your home can develop problems that prevent it from working reliably. Discover how experts can help you if your house’s furnace won’t stay on during the winter.
Inspect and Service the Pilot Light
The HVAC expert you hire may start the furnace’s servicing by inspecting its pilot light. When it operates normally, the furnace should burn a blue flame. An orange or yellow flame can indicate a problem like a gas leak or that the heater isn’t getting enough oxygen.
Service the Thermostat
The HVAC technician may also inspect the thermostat in your home. When the thermostat stops working, it can cause your heater to cycle constantly and not shut itself off. The heater may also short cycle, meaning it can turn itself on and off more frequently than usual. The technician can repair or replace the thermostat if it has damage like loose or frayed wiring.
Examine the Burners
The burners in your furnace can also malfunction. They can accumulate dirt and dust, causing the heater to make a burning smell when it runs. Dirty burners can also cause the heater to turn itself off. A technician can clean off the burners during your system’s annual furnace maintenance appointment.
Repair the Flame Sensor
If your furnace short cycles, it could have a faulty flame sensor. The flame sensor monitors and verifies if a flame is burning inside of your heater. When it malfunctions, it can’t detect the presence of the flame, causing the furnace to turn itself off prematurely.
Check the Blower Motor
The blower motor powers the fan in your furnace and plays a key role in warm air circulating throughout your house. When it stops working reliably, the blower motor will cause your heater to put out a weaker airflow. It can also cause the motor to overheat and shut down the entire heating system.
Inspect and Replace Power Supply Components
If your heater frequently trips its breaker, it could have damaged or loose wiring somewhere in its system. Frequent breaker tripping not only inconveniences you but also compromises the lifespan of your heater. During the inspection of your unit, the HVAC expert will check the electrical components like the breaker and replace or repair them to prevent this issue.
Inspect and Clean the Outdoor Unit
Your furnace can stop working because of a dirty outdoor unit. The outdoor unit can accumulate debris like grass clippings and dust. This buildup can impede how well the unit draws in and warms air in your home. The HVAC expert you hire can inspect and clean off the outdoor unit during your furnace’s yearly tune-up.
As you can see, HVAC technicians play an important role in making sure your furnace runs effectively and efficiently. If you need a furnace expert to assist with heaters in Bensalem, PA, then contact Hughes HVAC today.
