When winter’s chill sets in, the last thing you want to face is a furnace blower not working. It’s a common yet frustrating issue that can leave your home uncomfortably cold. At Trammell Heating & Air, we understand how crucial a functioning heating system is for your comfort and safety. 

In this guide, our HVAC company in Athens, GA, will explain common issues with furnace blower operation and when repairing a malfunctioning furnace blower is necessary. 

Common Causes of a Non-Working Furnace Blower

Understanding why your furnace blower is not working is the first step toward solving the problem. Here are some common furnace blower motor problems you might encounter:

Malfunctioning Thermostat

Sometimes, the issue is as simple as a thermostat not communicating properly with your furnace. This miscommunication can prevent your furnace from turning on or cause it to heat inconsistently. Regularly checking your thermostat’s batteries and settings helps it control your furnace properly.

Dirty Air Filters

Clogged filters can restrict airflow, causing the blower motor to overheat and shut down. Not only does this reduce your furnace’s efficiency, but it can also lead to increased energy bills and costly repairs if the blower motor sustains damage from overheating. Changing your air filters regularly, typically every 90 days, can help prevent these issues.

Faulty Blower Motor

Essential for pushing air through your ducts, a malfunctioning blower motor can halt furnaces entirely. Symptoms of a faulty blower motor include weak airflow, strange noises, or no air coming from your vents at all. It’s important to address these signs early to avoid further damage to your furnace.

Tripped Circuit Breaker

A tripped breaker can cut power to your furnace, leading to a furnace blower not working. This can happen if the system is overloaded or there’s a sudden surge of electricity. Frequent tripping may indicate a deeper electrical issue within your furnace or home’s electrical system, requiring a professional evaluation to guarantee safety and functionality.

Tripped Circuit Breaker

A tripped breaker can cut power to your furnace, preventing the blower from operating. This often happens when the system is overloaded. Checking your home’s electrical panel and resetting any tripped breakers can quickly solve this issue and restore power to your furnace.

Worn Blower Belt

Older furnace models often use a belt-driven blower motor. Over time, this belt can wear out, become loose, or break, leading to a non-working blower. A telltale sign of a worn blower belt is a high-pitched squealing from the furnace. Replacing the belt is a straightforward fix that can restore functionality to your blower.

Blocked Air Vents

Sometimes, the problem isn’t with the furnace but blocked or closed air vents throughout your home. Furniture or curtains can block vents, restricting airflow and putting unnecessary strain on your blower motor. Ensuring all vents are open and unblocked allows for proper air circulation, reducing stress on your furnace and preventing potential blower issues.

Troubleshooting Tips for a Faulty Heating System Blower

Before calling in the professionals, there are a few troubleshooting steps you can take to possibly remedy a furnace blower not working:

  • Check your thermostat settings: Confirm that your thermostat is on “heat” and that the temperature setting is higher than the current room temperature.
  • Inspect and replace air filters: A clean filter can make a significant difference in your furnace’s performance.
  • Reset your furnace: Sometimes, a simple reset can kickstart your blower motor back into action.

If these steps don’t resolve the issue, it might be time to call in a professional for furnace repair to diagnose and fix the problem.

Trammell Heating and Air: Frequently Asked Questions About Furnace Troubles

The average lifespan of a furnace is around 15 to 20 years, but several factors can influence this. For a more accurate estimate on your specific furnace, call Trammell Heating and Air at 770-925-5506 for a professional assessment. We offer free, no-obligation quotes for heating and cooling system replacements.

Furnaces don’t always go out with a bang, but there are warning signs to watch for. These include:

  • Strange noises: Clanking, grinding, or unusual humming noises could indicate failing components.
  • Inconsistent heating: If your home isn’t heating evenly or struggles to maintain a comfortable temperature, your furnace might be struggling.
  • Increased energy bills: A less efficient furnace will work harder to maintain warmth, leading to higher energy costs.
  • Pilot light issues: If your gas furnace has a constantly flickering or extinguished pilot light, it’s a sign of trouble.

If you notice any of these signs, don’t wait! Call Trammell Heating and Air at 770-925-5506 for prompt service and prevent a complete breakdown.

Furnaces have several components that can wear down over time. Some common failing parts include:

  • Igniter: This component lights the gas burner, and if it malfunctions, the furnace won’t ignite.
  • Flame sensor: This safety feature ensures the pilot light is on, and a faulty sensor can prevent the furnace from operating.
  • Blower motor: The blower motor circulates warm air throughout your home. If it fails, you’ll lose heat.
  • Heat exchanger: This crucial component transfers heat from the combustion chamber to the air. Cracks or damage can lead to safety hazards and require immediate attention.

Dirty air filters are a leading cause of furnace problems. A clogged filter restricts airflow, reducing efficiency and causing the furnace to work harder. Make sure to replace your air filter according to the manufacturer’s recommendations.

Replacing clogged air filters is a simple task you can often handle yourself. However, if you’re facing other furnace issues, call Trammell Heating and Air at 770-925-5506 for expert diagnosis and repair.

The heat exchanger is often the most expensive component to repair or replace in a furnace. Because it’s vital for safe operation, any issues with the heat exchanger require immediate attention from a qualified technician.

If you have any concerns about your furnace, don’t hesitate to call Trammell Heating and Air at 770-925-5506. Our experienced technicians can diagnose the problem and provide you with the best course of action.
