Are you experiencing a frustrating issue with your furnace struggling to stay lit? It can be a hassle, especially during the colder months when you rely on your heating system to keep your home warm and comfortable. At Sunbeam Service Experts, we understand the importance of a properly functioning furnace, and we are here to help you find a solution. Let's dive into some common reasons why furnaces may have trouble staying lit.

1. Gas Supply Issues

One of the primary reasons why your furnace may not stay lit is a problem with the gas supply. If the gas valve is malfunctioning or there is a blockage in the gas line, it can lead to inconsistent fuel flow, causing the flame to go out. Our team of experts can inspect your gas supply system, including the gas valve, regulator, and gas line, to identify and resolve any issues.

2. Dirty or Faulty Flame Sensor

A dirty or faulty flame sensor is another common culprit behind furnaces going out. The flame sensor is responsible for detecting whether a flame is present. If it becomes dirty or covered with residue over time, it may not be able to accurately sense the flame, causing the system to shut down for safety reasons. Our technicians can clean or replace the flame sensor as necessary, ensuring proper functioning of your furnace.

3. Clogged Air Filter

A clogged air filter can restrict proper airflow to your furnace, causing it to overheat and shut down. It is important to regularly check and replace your air filter to prevent this issue. Sunbeam Service Experts offers comprehensive maintenance services, including filter cleaning and replacement, to keep your furnace operating efficiently.

4. Ignition Control Problems

Furnaces rely on ignition controls to initiate the heating process. If the ignition control module or ignition switch malfunctions, it can result in the furnace failing to ignite or stay lit. Our skilled technicians can diagnose and repair ignition control issues, ensuring reliable operation of your heating system.

5. Pilot Light Troubles

If your furnace has a pilot light, it is crucial for it to remain lit. A pilot light that keeps going out may indicate a problem with the pilot assembly, such as a faulty thermocouple or blocked orifice. Our experts have the knowledge and tools to troubleshoot and fix pilot light problems, allowing your furnace to function properly again.

6. Improper Venting

Inadequate venting can cause a furnace to shut down for safety reasons. Blocked or improperly installed vent pipes can lead to the accumulation of harmful gases, such as carbon monoxide, within your home. Our team can assess your venting system to ensure it is properly installed and free from obstructions, helping you avoid not only furnace issues but also potential health hazards.

7. Electrical Malfunctions

In some cases, electrical malfunctions can contribute to furnace burnout. Issues such as a faulty thermostat, wiring problems, or a malfunctioning control board can disrupt the ignition process and cause the system to shut down. Our technicians are experienced in diagnosing and resolving electrical issues, restoring your furnace's functionality.
