If your furnace isn’t turning on, don’t sweat it! We’ve got some simple troubleshooting steps you can try. With winter almost here, your furnace is ready to keep things cozy, but nothing’s worse than expecting a warm home and finding out your furnace isn’t kicking in.
Before you panic and call your Springboro Heating & Cooling pros, remember there are a few common issues that could be causing the hiccup in your heating system. So, let’s dive into a quick and easy troubleshooting guide to help you figure things out!
Check the Power Source
First up, let’s check the power source. There are two main power sources to look at, depending on your furnace type: the circuit breaker and the gas or oil supply.
Think About the Circuit Breaker: If your furnace runs on electricity, checking the circuit breaker is crucial. Sometimes, the breaker for your furnace trips, cutting the power to your heating system. So, take a peek at your electrical panel and check for any switches that are in the “off” position or stuck somewhere between “on” and “off.” You’d be surprised how often a switch can look like it’s on when it’s actually in the middle and not working!
To fix it, just reset any tripped switches by flipping them fully to “off” and then back to “on.” If it trips again, there might be a bigger electrical issue that needs a pro’s attention. And keep in mind that circuit breakers can wear out over time, so if this keeps happening, you might want to chat with a professional about repair or replacement options.
Think About the Fuel Supply: If your furnace runs on fuel, it’s important to make sure it has a steady supply. Any hiccups with the fuel supply, like a closed valve or an empty oil tank, can keep your furnace from firing up. Feel free to check that the gas valve is in the right position, but if you think there’s an issue with the gas pressure, it’s best to leave that to the pros.
Check the Thermostat If Your Furnace Isn’t Turning On
First things first, let’s check the thermostat. It’s basically the command center for your HVAC system, so if your furnace isn’t firing up, the thermostat might be the culprit. Make sure it’s set to “heat” and that the temperature is set higher than what it currently is in the room. This gives your heating system a chance to kick in and warm things up.
Sometimes, the thermostat itself can be a bit finicky. It happens! If it’s not responding, check the batteries and swap them out if needed. If it’s still not playing nice, that’s a good sign it might be time to call in an HVAC technician for a proper diagnosis.
Check the Air Filters If Your Furnace Isn’t Turning On
Now, how about those air filters? Have you given them a look? It might seem small, but a clogged filter can really mess with your furnace’s performance. A dirty filter can block airflow, causing your furnace to overheat and shut down to protect itself. So, if your furnace is still not working, checking the air filters is a smart move.
If you find a dirty filter, just replace it with a fresh one. And remember, changing your air filter regularly is super important—ideally every 1-3 months—to keep your HVAC system running smoothly and extend its life.
Check if the Ducts are Blocked If Your Furnace Isn’t Turning On
Did you know that blocked ducts can also throw a wrench in your furnace’s operation? If airflow gets blocked, it can signal to your furnace that something’s off, causing it to shut down. If something has fallen into the ductwork, that could definitely send your furnace into safety mode and keep it from turning on.
Some furnaces are wired to respond this way to prevent carbon monoxide poisoning. While it takes a few things to happen for this to be a concern, your safety is the most important thing, so it’s best to clear any blockages as soon as you can.
Check the Drain Pan If Your Furnace Isn’t Turning On
Here’s another thing to check: the drain pan. If it’s full of water, it can trigger a safety switch that stops your furnace from running. If you find your drain pan is overflowing, find it (usually under the furnace) and empty it out.
If this keeps happening, it might mean there’s a drainage issue with your HVAC system. In that case, don’t hesitate to reach out to us for help!
Let’s Wrap It Up
Dealing with a furnace that won’t turn on can be a hassle, but usually, you can tackle it with the steps we just talked about. By checking the circuit breaker, thermostat, air filter, ducts, drain pan, pilot light, and fuel supply, you can often figure out what’s wrong on your own.
