Identifying Problems With Your Furnace's Heating Element

The heart of your furnace's efficiency lies in its heating element. But how can you tell if it's failing?

Here are some of the common signs of a faulty heating element in a furnace. Understanding these signs can help you identify when it's time to call a professional for a thorough inspection and necessary repairs.

Inadequate Heating

If your furnace isn't providing enough heat, the heating element might be the culprit.

Increased Energy Bills

A struggling furnace often consumes more energy. If your bills are rising without a change in usage, the heating element might be causing system strain.

Frequent Cycling

If your furnace turns on and off more frequently than usual, it could be due to a malfunctioning heating element struggling to maintain the desired temperature.

Age of Furnace

Older furnaces are more prone to heating element issues. If your furnace is over 15 years old, wear and tear on the heating element is more likely.

Unusual Noises

Rattling or buzzing noises can indicate a loose or damaged heating element.

Burning Smell 

A distinct burning smell when the furnace runs could signal an overheating element, often due to dirt accumulation or electrical issues.

Common Causes of Heating Element Issues

If you want to learn how to tell if a heating element is bad in a furnace, you need to know the most common causes of this problem. 

Several factors can contribute to a malfunctioning heating element: 

• Faulty wiring, often due to age or poor installation, can disrupt the power flow, causing your furnace to underperform or stop working altogether. 
• Corrosion, a common issue in older systems, can also impede the heating element's functionality.
• Regular wear and tear are inevitable, but without proper maintenance, it can lead to premature breakdowns. 
• Furnace sequencer issues can also affect the heating element's efficiency. The sequencer's job is to regulate the heating elements' operation, ensuring they don't overload your electrical system. If it fails, it can cause the elements to malfunction.
• A faulty limit control, which prevents overheating, can also lead to heating element issues.
• Dust and debris accumulation is another factor that can affect the heating element, leading to inefficiency and potential fire hazards. 
• Environmental factors, such as humidity and temperature fluctuations, can also impact the heating element's performance over time.

Troubleshooting and Professional Help

If you suspect your heating element is bad, the first step is to check for visible signs of damage like burn marks or corrosion. However, diagnosing and repairing these issues often requires professional expertise. An HVAC expert can examine the system and consider factors in heating element issues, such as:

• Thermal Stress: Repeated heating and cooling cycles can cause thermal stress, leading to cracks or breaks in the heating element.
• Electrical Surges: Unexpected electrical surges can damage the heating element, reducing its lifespan and efficiency.
• Improper Sizing: If the heating element is not correctly sized for the furnace, it can lead to inefficiencies and potential malfunctions.
• Ventilation Issues: Poor ventilation can cause the heating element to overheat, potentially damaging it or triggering safety shut-offs.

Remember, dealing with electrical components can be dangerous, whether on a furnace or other HVAC system. It's always safer and more efficient to seek help from experts like Watson Heating & Air for professional repair.
