If your furnace is not working, common causes include a dirty air filter, thermostat problems, ignition failure, or a faulty flame sensor. Some issues are simple to check, while others require professional furnace repair to restore heat safely.
For homeowners in Papillion, NE, losing heat during winter can quickly become uncomfortable. At Andy’s Heating and Cooling, our technicians diagnose furnace problems, identify faulty components, and recommend the appropriate repairs.
Recently, our team helped a Papillion homeowner whose furnace needed a new flame sensor. After replacing the faulty component, the heating system returned to normal operation.
What Are the Most Common Reasons a Furnace Stops Working?
A furnace not working properly can have several possible causes. Understanding the common warning signs helps homeowners know when professional service may be necessary.
Common furnace problems include:
- Dirty furnace filter: A clogged filter restricts airflow and may cause the system to overheat.
- Faulty thermostat: Incorrect settings or a malfunctioning thermostat can prevent the furnace from starting.
- Bad flame sensor: A dirty or faulty flame sensor can cause gas burners to shut off shortly after ignition.
- Ignition problems: A failed igniter may prevent the furnace from producing heat.
- Electrical problems: A tripped breaker or faulty internal component can interrupt furnace operation.
If basic checks do not restore heating, a qualified technician can inspect the system and identify the underlying problem.
Why Is My Furnace Not Turning On?
When a furnace is not turning on, check the thermostat first. Make sure it is set to Heat and the requested temperature is higher than the room temperature.
Next, confirm that the furnace has power and check whether the circuit breaker has tripped.
If the furnace still refuses to start, the problem may involve the ignition system, thermostat wiring, or another electrical component.
Avoid repeatedly resetting a furnace that continues to malfunction. Professional diagnosis can help identify the issue without unnecessary part replacements.
Why Is My Furnace Running but Not Heating?
A furnace not heating properly may have an ignition problem, restricted airflow, or a faulty flame sensor.
A common complaint is a furnace blowing cold air even though the blower continues running. This can happen when the burners fail to ignite or shut down unexpectedly.
In a gas furnace, the flame sensor helps confirm that a burner flame is present. If the sensor cannot detect the flame correctly, the system may shut off the gas supply as a safety measure.
A damaged or dirty flame sensor can therefore prevent the furnace from maintaining heat.
How Did Andy’s Heating and Cooling Repair a Furnace in Papillion, NE?
A homeowner in Papillion, Nebraska, recently contacted Andy’s Heating and Cooling because their furnace wasn’t working properly.
Our technician arrived and performed a diagnostic inspection to determine why the heating system was malfunctioning.
During the inspection, the technician identified the problem: the furnace needed a new flame sensor.
Fortunately, the replacement flame sensor was available in our technician’s truck stock. This allowed the repair to be completed during the same visit without waiting for a replacement part.
After installing the new flame sensor, the furnace returned to full functionality, restoring warmth and comfort to the homeowner’s property.
This repair demonstrates how identifying the correct faulty component can help resolve a heating problem without unnecessary replacements or upsells.
Why Does My Furnace Keep Shutting Off?
A furnace that starts but shuts down shortly afterward may have a flame sensor problem, overheating issue, or another malfunction.
Possible causes include:
- A dirty or failing flame sensor
- A clogged furnace filter
- Restricted airflow
- A malfunctioning thermostat
- Problems with internal safety controls
A faulty flame sensor can cause the burners to shut off shortly after ignition, even if the furnace initially starts normally.
If your furnace is not working consistently or repeatedly stops heating, schedule an inspection instead of repeatedly restarting the system.
A technician can check the flame sensor and other components to determine what is causing the shutdown.
