If your furnace isn’t turning on, don’t worry; we’ve got some easy troubleshooting steps for you! With winter almost here, it’s time for your furnace to shine, and as a homeowner, there’s nothing worse than expecting a cozy, warm home only to find your furnace isn’t working.
Before you panic and call your Xenia Heating & Air pros, let’s take a look at some common issues that might be messing with your heating system. Here’s a quick and simple troubleshooting list to help you figure out what’s going on and hopefully get it fixed!
Check the Power Source If Your Furnace Isn’t Powering On
There are two main power sources you should check, depending on your furnace type: the circuit breaker and the gas or oil supply.
The Circuit Breaker: If your furnace runs on electricity, start here. Sometimes, the breaker for your furnace might trip and cut off power. Head over to your electrical panel and see if any switches are in the “off” position or caught somewhere between “on” and “off.” It’s actually pretty common for a breaker switch to look like it’s on when it’s really in the middle!
To fix it, just reset any tripped breakers by flipping them all the way to “off” and then back to “on.” If it trips again, there might be an underlying electrical issue that needs a pro’s help. And remember, circuit breakers can wear out over time, so if this keeps happening, it might be smart to chat with a professional about whether you need a repair or replacement.
Check the Natural Gas or Oil Supply: If your furnace runs on fuel, it needs a steady supply to work. Any hiccups with the fuel supply, like a closed valve or an empty oil tank, can keep your furnace from turning on. It’s safe to check if 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 Powering On
First things first, let’s take a look at the thermostat. It’s really the command center for your HVAC system! If your furnace isn’t kicking on, the fix might be as simple as adjusting the thermostat. Check if it’s set to “heat,” and make sure the temperature is higher than what’s currently in the room. This gives your heating system a chance to warm things up to your comfy level.
Sometimes, the thermostat itself can act up. It happens! If that’s the case, check the batteries and swap them out if needed (depending on your thermostat model). If it’s still not responding, it might be time to call in an HVAC technician for a proper check-up.
Check the Air Filters If Your Furnace Isn’t Powering On
Next up, have you checked your air filters? It might seem like a small thing, but a clogged filter can really mess with your furnace’s performance. When the filter gets dirty and filled with dust, it restricts airflow, causing the furnace to overheat and shut down for safety. So, if you haven’t checked this yet, it’s a smart move to do so! Just swap out the dirty filter for a new one. And remember, changing the air filter regularly—ideally every 1-3 months—can help your HVAC system run better and last longer.
Check the Ducts If Your Furnace Isn’t Powering On
Now, let’s talk ducts! Did you know blocked ducts can stop your furnace from working properly? If airflow gets blocked, it might send a signal that something’s off, causing the furnace to shut down. For example, if something falls into the ductwork, it could trigger some furnaces to go into safety mode and not turn on. Certain furnaces are designed this way to protect you from carbon monoxide poisoning. Your safety is super important, so it’s always best to check for any blockages right away.
Check the Drain Pan If Your Furnace Isn’t Powering On
Another thing to check is the drain pan. Modern furnaces have a safety feature where if the drain pan collects too much moisture, it can trip a safety switch and stop the furnace from running. If you’re still having issues, find the drain pan (it’s usually below the furnace) and empty it if it’s full of water. Also, if you notice the drain pan filling up a lot, that could indicate a drainage issue with your HVAC system. If that’s the case, it’s time to give us a call!
So, let’s wrap it up!
Dealing with a furnace that won’t turn on can be super frustrating, but usually, you can sort it out with some easy troubleshooting. By checking the circuit breaker, thermostat, air filter, ducts, drain pan, pilot light, and fuel supply, you can often pinpoint and fix the issue yourself.
