If your furnace isn’t turning on, don’t worry; we have some simple troubleshooting steps for you to try. With winter here, it’s time for your furnace to work hard this season and the next. As a homeowner, there’s nothing worse than expecting a warm and cozy home only to find your furnace unresponsive.
Before you panic and call your Pickerington Heating & Cooling professionals, remember that several common issues could be causing your heating system to malfunction. Here’s a straightforward troubleshooting guide to help you identify and fix the problem.
Check the Power Source If Your Furnace Isn’t Working
First, check the power source. As the saying goes, “With great power, comes great responsibility.”
Jokes aside, there are two main power sources to look at, depending on your furnace type: the circuit breaker or the gas/oil supply.
The Circuit Breaker: If your furnace runs on electricity, check the circuit breaker. It may have tripped, cutting power to your heating system. Look at your electrical panel for any switches that are in the “off” position or between “on” and “off.” Sometimes, a breaker might look like it’s on but is actually in the middle position.
To fix this, reset any tripped breakers by flipping them fully to “off” then back to “on.” If the breaker trips again, there might be an electrical issue that needs a professional’s help. Also, be aware that circuit breakers can wear out over time, so if this happens often, consult a professional about whether to repair or replace the breaker.
The Natural Gas or Oil Supply: If your furnace uses fuel, it needs a steady supply to operate. Issues like a closed valve or an empty oil tank can stop your furnace from turning on. You can safely check if the gas valve is positioned correctly, but if you suspect a problem with the gas pressure, it’s best to call in the professionals.
Check the Thermostat If Your Furnace Isn’t Turning On
First, let’s check the thermostat, as it’s the control center for your HVAC system. If your furnace isn’t starting, the thermostat might be the easy fix you need. Make sure your thermostat is set to “heat” and that the temperature setting is higher than the current room temperature, allowing your heating system to kick in.
Sometimes, the thermostat may not work properly. Check the batteries and replace them if necessary. If your thermostat still isn’t responding, it might be time to call an HVAC technician for a proper diagnosis.
Check the Air Filters If Your Furnace Isn’t Turning On
Next, don’t forget about your HVAC system’s air filters. A clogged air filter can significantly impact your furnace’s performance. When the filter is dirty, it restricts airflow, which can cause the furnace to overheat and shut down as a safety precaution. If you haven’t resolved the issue yet, checking the air filters is a smart move.
If the filter is dirty, simply replace it. Make it a habit to change the air filter every 1-3 months to help your HVAC system run efficiently and extend its lifespan.
Check if the Ducts Are Blocked If Your Furnace Isn’t Turning On
Did you know that blocked ducts can stop your furnace from working properly? When airflow is blocked, the furnace may shut down as a safety measure. For example, if anything has fallen into the ductwork, it could trigger a safety mode that prevents the furnace from turning on.
This safety feature helps prevent carbon monoxide poisoning in your home. While this situation is rare, it’s important to address any obstructions as soon as possible for your safety.
Check the Drain Pan If Your Furnace Isn’t Turning On
Modern furnaces have safety features, including a drain pan that collects moisture. If it gets too full, it can trigger a switch that stops the furnace from operating. If you’re still having issues, locate the drain pan (usually under the furnace) and carefully empty it if it’s full.
If the drain pan fills up often, this could indicate a drainage problem in your HVAC system, and it’s time to give us a call.
Let’s Wrap It Up
Having a furnace that won’t turn on can be frustrating, but you can often resolve it by following these troubleshooting steps. By checking the circuit breaker, thermostat, air filter, ducts, drain pan, pilot light, and fuel supply, you can usually identify and fix the problem yourself.
