Common Causes and Solutions
When temperatures drop, the last thing you want is to discover your furnace not kicking on. A malfunctioning furnace can leave you and your family without heat, causing discomfort and potential safety issues. Fortunately, many common furnace problems can be diagnosed and resolved quickly. In this guide, the experts at Element Air Heating and Cooling will walk you through potential causes, troubleshooting tips, and when to call a professional.
7 Reasons Your Furnace Won’t Turn On
There are several possible reasons why your furnace is not turning on, ranging from simple fixes to more complex HVAC issues. Here’s what to check:
1. Thermostat Issues
Your thermostat controls your furnace’s operation, so if it’s not set correctly, your heating system won’t run. Make sure:
- The thermostat is set to “heat” mode.
- The temperature setting is higher than the current room temperature.
- The batteries (if applicable) aren’t dead.
2. Tripped Circuit Breaker
A tripped breaker can cut power to your furnace. Locate your electrical panel and check if the furnace switch has flipped to the “off” position. If so, reset it and monitor for further issues.
3. Dirty or Clogged Air Filter
A clogged air filter can restrict airflow, causing your furnace to shut down to prevent overheating. Replace dirty filters every 1-3 months to maintain efficiency and airflow.
4. Pilot Light or Ignition Issues
If you have an older gas furnace, check if the pilot light is out. For newer models with electronic ignition, listen for clicking noises that indicate ignition failure. If your furnace isn’t lighting properly, you may need a professional furnace repair service.
5. Faulty Flame Sensor
A dirty or faulty flame sensor can prevent your furnace from staying on. This sensor detects the burner flame, and if it’s covered in dirt or corrosion, it will shut down the furnace as a safety measure. A professional technician can clean or replace this component.
6. Gas Supply Issues
If your furnace runs on natural gas, check that the gas valve is open. If you suspect a gas supply issue, avoid DIY fixes—contact a certified HVAC technician immediately.
7. Blower Motor or Limit Switch Failure
If your furnace turns on but doesn’t blow warm air, the blower motor or limit switch could be malfunctioning. A technician can inspect and repair these components to restore proper function.

FAQs
How do I reset a furnace?
If your furnace isn’t kicking on, a reset might help. First, turn off the power to your furnace at the circuit breaker. Then, locate the reset button—usually a red or yellow button near the burner. Press and hold it for about 30 seconds, then turn the power back on. If your furnace still won’t start, you may need a professional furnace repair service to diagnose the issue.
I can hear my furnace click on, but it does not fire up. What should I do?
If you hear clicking but your furnace won’t ignite, the issue could be a faulty ignitor, dirty flame sensor, gas valve problem, or a clogged air filter. Try replacing the air filter and ensuring your gas supply is on. If the problem persists, call a professional to inspect your furnace ignition system and perform necessary repairs.
How much does it cost to replace a furnace blower motor?
Replacing a furnace blower motor typically costs between $400 and $1,500, depending on the model and labor. If your blower motor is making unusual noises, running inefficiently, or not working at all, it may be time for a replacement. Our technicians at Element Air Heating and Cooling can inspect your system and provide an affordable solution.
How expensive is a new furnace?
The cost of a new furnace varies depending on the size, efficiency, and type of system you need. On average, homeowners pay between $3,000 and $7,000 for a new high-efficiency furnace installation. Investing in a new furnace can lower your energy bills and provide reliable heating for years to come. Contact us for a free estimate on furnace replacement.
How can I tell if my furnace ignitor is bad?
A failing furnace ignitor can prevent your system from heating properly. Signs of a bad ignitor include:
- The furnace clicks but doesn’t ignite.
- There’s no heat coming from the vents.
- The ignitor looks cracked or damaged.
- Your furnace cycles on and off frequently.
If you suspect a bad ignitor, it’s best to schedule a furnace repair service. Ignitor replacement is an affordable fix that can restore your furnace’s functionality.
