Experiencing a furnace clicking but not turning on can be a frustrating ordeal, especially during the colder months in Atlanta. While it's a common issue, understanding the reasons behind why your furnace is clicking but not turning on can help you take the right steps toward a solution.
Troubleshooting the Thermostat
The first thing to check is your thermostat. It might be clicking yet failing to trigger the heating. Ensure it's set to 'heat' mode and the temperature is above the current room temperature. Incorrect settings or a malfunctioning thermostat can be a primary reason for the furnace clicking but not turning on.
A common culprit is the ignition system. For older furnaces, check if the pilot light has gone out. Here's a brief guide to handling this:
- Turn off the furnace: Ensure your safety by powering down the furnace.
- Locate the pilot light: Found near the furnace's bottom.
- Gas valve check: Ensure the valve is on.
- Find the reset button: Near the pilot light, it's usually colored red or blue.
- Inspect the pilot light: Check if it's lit.
- Relighting steps: Turn off the gas, wait, set it to 'pilot,' ignite with a lighter while pressing the reset button, then release and set the valve to 'on.'
If you're not comfortable with these steps or the pilot doesn't stay lit, it's time to call a professional.
Air Filter Issues
A blocked air filter is another reason why the furnace is running constantly or not turning on at all. Replace a dirty filter by:
- Locating the filter: Usually in the blower compartment.
- Turn off the furnace: Safety first.
- Remove and replace the filter: Slide out the old one and insert a new one that matches the specifications.
Regularly changing your air filter, especially during high usage or if you have pets, is vital for efficient heating in Atlanta.
Checking the Blower
A non-responsive blower can lead to a furnace making noise but not producing heat. If the blower motor is faulty or the belt is damaged, it's a signal for professional help.
Electrical issues, such as a tripped breaker or a blown fuse, can also be the reason your furnace is struggling. A quick check of your home's electrical panel could reveal and resolve this issue.
