The Common Causes of a Broken Furnace

Fixing a broken furnace


As winter approaches, the last thing anyone wants is a malfunctioning furnace. The warmth and comfort provided by a properly functioning heating system are essential during the colder months. When your furnace unexpectedly breaks down, it can leave you in the cold—both literally and figuratively.

Common Causes of a Broken Furnace

In this blog post, we’ll explore some common culprits behind a broken furnace and discuss how CampbellCare, your trusted plumbing, heating, and air company, can come to the rescue.


1. Lack of Maintenance

One of the most frequent reasons for furnace issues is neglecting regular maintenance. Over time, dust, debris, and other particles can accumulate, affecting the efficiency of your heating system. Routine check-ups and cleanings by professionals can prevent breakdowns and ensure your furnace operates smoothly.

2. Dirty or Clogged Filters

Dirty or clogged filters restrict airflow, making your furnace work harder to produce heat. This increased strain can lead to overheating and eventual breakdowns. Regularly changing or cleaning your furnace filters is a simple yet effective way to maintain its functionality.

3. Ignition or Pilot Control Problems

Issues with the ignition or pilot control can result in a furnace failure. Faulty components, thermocouple problems, or issues with the flame sensor may cause your furnace to refuse to ignite. Expert technicians, like those at Campbell Care, can diagnose and fix these ignition-related issues efficiently.

4. Malfunctioning Thermostat

The thermostat is the control center of your heating system. If it malfunctions, it may not signal the furnace to turn on or regulate the temperature accurately. Regularly checking and calibrating your thermostat can prevent unnecessary breakdowns.

5. Wear and Tear on Parts

Like any mechanical system, furnaces experience wear and tear over time. Components such as belts, bearings, and motors can wear out, leading to operational issues. Professional maintenance can identify and replace worn-out parts before they cause a complete breakdown.

6. Gas Supply Issues

If your furnace relies on natural gas, issues with the gas supply can lead to malfunctions. Gas valve problems, a closed gas valve, or a gas line leak can compromise the heating process. Gas-related issues should be addressed promptly by qualified technicians.

When faced with a broken furnace, it’s crucial to have a reliable and experienced team to turn to. With years of expertise in plumbing, heating, and air services, Campbell Care is your go-to partner for furnace repair and maintenance.
