Quick Fixes for Common Furnace Problems

Is your furnace acting up just when you need it the most? 

Don’t worry you are not alone! Furnaces can run into hiccups, especially during heavy use in the colder months. 

But before you panic and call a professional, some issues can be resolved with quick, simple fixes. 

So what are the common furnace problems and how to address them?

1. Ignition Troubles

If your furnace won’t ignite, you might be dealing with a dirty burner, a faulty igniter, or an insufficient gas supply.

Quick Fix –

  • For older furnaces, inspect the igniter for cracks or damage and clean the burner with a soft brush.
  • Make sure the gas valve is open and the supply line is clear.
  • Replace filters on newer models to ensure proper airflow.

If none of these steps work, it’s time to call an HVAC professional for a detailed inspection.

2. Furnace Won’t Stop Running

Does your furnace feel like it’s running a marathon? It could be due to the thermostat being set to “fan mode” or a malfunctioning fan limit switch.

Quick Fix –

  • Check your thermostat and switch it from “fan” to “auto” mode to ensure the fan only runs when heating.
  • If the issue persists, reset the fan limit switch. If damaged, call a technician for a replacement.

3. Pilot Light Problems

A flickering or extinguished pilot light can spell trouble. Drafts, dirt in the gas tubes, or a faulty thermocouple could be to blame.

Quick Fix –

  • Relight the pilot light if it’s gone out.
  • Check for dirt or debris in the gas tubes and clean if needed.
  • Replace a faulty thermocouple or pressure switch if they are preventing the gas flow.
    If the pilot light burns yellow, contact a technician immediately, as it could indicate a carbon monoxide issue.

4. Thermostat Issues

If your furnace isn’t heating as it should, the thermostat might be miscalibrated or in the wrong spot.

Quick Fix –

  • Reset or recalibrate the thermostat to ensure it’s reading accurately.
  • Replace batteries if it’s battery-operated.
  • Place the thermostat away from drafts or direct sunlight for more accurate readings.

5. Dirty Air Filters

Clogged air filters can restrict airflow, causing your furnace to overheat and shut down.

Quick Fix –

  • Inspect filters and replace them if clogged or damaged.
  • Aim to clean or replace filters every three months, or more often if you have pets or allergies.

When to Call the Pros

If these quick fixes don’t solve the furnace problem, it’s best to call a professional for a thorough check-up. Regular maintenance can also help prevent these issues from happening in the first place.
