Why Do Furnaces Stop Working?
Furnaces can stop working for several reasons. Older systems may fail as they reach the end of their lifespan, while others might develop issues due to worn-out components. Some common causes include:
- Power issues – Tripped circuit breakers or blown fuses.
- Thermostat malfunctions – Incorrect settings or dead batteries.
- Dirty air filters – Clogged filters can restrict airflow and cause shutdowns.
- Pilot light issues – Gas furnaces require a lit pilot light to function.
- Component failures – Problems with the blower motor or ignition system.
Common Furnace Problems
Here are some common furnace issues that homeowners encounter:
- Not turning on – This can be due to thermostat issues, power problems, or a faulty ignition system.
- Blowing cool air – If your furnace runs but doesn’t produce heat, the blower motor or other components might be malfunctioning.
- Making strange noises – Banging, squealing, or rattling sounds often signal mechanical issues.
- Short cycling – If your furnace turns on and off frequently, dirty filters, thermostat malfunctions, or airflow issues could be the cause.
Troubleshooting Your Furnace
If your home is getting colder and your furnace isn’t turning on, try these steps before calling for repairs.
1. Check for Power
- Even gas furnaces need electricity to operate. Check the breaker box for tripped circuits or blown fuses.
- If your furnace has a power switch, ensure it’s turned on.
2. Inspect Thermostat Settings
- Make sure the thermostat is set to “heat” mode.
- Increase the temperature a few degrees higher than room temperature.
- If your thermostat runs on batteries, replace them.
3. Change the Air Filter
- Dirty air filters restrict airflow and may cause your furnace to shut down.
- Check your filter and replace it if it’s clogged with dust and debris.
4. Check the Pilot Light (For Gas Furnaces)
- If the pilot light is out, follow your manufacturer’s instructions to relight it safely.
- Ensure the gas valve is turned to the “on” position.
- If you smell gas, leave your home immediately and call 911 or the FortisBC emergency line at (800) 663-9911.
5. Call a Professional for Help
- If troubleshooting doesn’t fix the issue, a technician can diagnose and repair the problem.
- Persistent issues may mean it’s time to consider a furnace replacement.
Preventing Furnace Problems
Regular furnace maintenance can help prevent unexpected breakdowns. HVAC professionals can:
- Inspect and clean components.
- Check for wear and tear.
