Is your furnace refusing to fire up? Don’t panic! We’ve got some simple troubleshooting steps to help you out. With winter in full swing, your furnace is ready to keep you warm and cozy. As a homeowner, there’s nothing worse than looking forward to a snug home only to discover that your furnace has other plans. Let’s get it back in action so you can enjoy the warmth you deserve!
Before you hit the panic button and call your Milford Heating & Cooling pros, take a breath! There are quite a few common issues that might be behind your heating system’s hiccups. So, let’s dive in! Here’s a quick and easy troubleshooting guide to help you tackle some basic furnace issues, pinpoint the problem, and get your warmth back on track!
If You Have a Furnace That Won’t Power On, Inspect the Power Source
The first thing you should do when troubleshooting a problem is to check the power source. After all, “With great power, come great responsibility,” … or so they say.
Jokes aside, there are two main power sources you may need to check depending on what type of furnace you have. These are the circuit breaker or the gas or oil supply.
Think About the Circuit Breaker: If your furnace is electric, it’s time to take a quick peek at your circuit breaker! Sometimes, the power to your heating system can get interrupted if the circuit breaker for your furnace has tripped. Make sure to check your electrical panel for any switches that are in the “off” position or teetering between “on” and “off.” You might be surprised—often, a breaker switch can appear to be in the “on” position while actually being stuck in the middle, leaving your furnace without power. A simple adjustment could get your home toasty warm again!
To resolve this, simply reset any tripped breaker switches by flipping them all the way to “off” and then back to “on.” If the breaker trips again, it could indicate a deeper electrical issue that needs a pro’s expertise. Remember, it’s completely normal for circuit breakers to wear out with time. If this keeps happening, it might be time to chat with a professional about whether a circuit breaker repair or replacement is the best route for you.
Think About the Fuel Supply: If your furnace relies on fuel, it’s crucial to ensure it has a steady supply to keep running smoothly. A simple closed valve or an empty oil tank could be the reason your furnace won’t start. While it’s safe to check that the gas valve is in the right position, we recommend calling in the pros if you suspect any issues with gas pressure. Stay warm and cozy this season!
If You Have a Furnace That Won’t Power On, Inspect the Thermostat
Next up, let’s dive into checking the thermostat—it’s the command center of your HVAC system! If your furnace isn’t firing up, the answer could be as simple as adjusting the thermostat. Take a moment to inspect it: make sure it’s set to “heat” and that the temperature is higher than the current room temperature. This gives your heating system the nudge it needs to warm things up to your desired level. Let’s get cozy!
Sometimes, your thermostat might just decide to play hard to get! It happens to the best of us. First, check the batteries and swap them out if your model requires it. If your thermostat is still unresponsive, it might be time to call in a pro. An HVAC technician can give it a thorough check-up and ensure everything’s running smoothly!
If You Have a Furnace That Won’t Power On, Inspect the Air Filters
What about your HVAC system’s air filters? Have you checked those? It may sound miniscule, but a clogged air filter can severely affect your furnace’s performance. When the air filter is dirty and overloaded with dust particles and other airborne contaminants, it restricts airflow, causing the furnace to overheat and shut down as a safety measure. So, checking on your air filters if the problem has not yet been resolved is a prudent measure.
If your filter is dirty, don’t hesitate to swap it out for a fresh one! Remember, regularly changing your air filter is key to keeping your HVAC system running smoothly. Aim to do this every 1-3 months—it’s a simple task that can boost efficiency and extend the lifespan of your system. Your comfort and savings will thank you!
If You Have a Furnace That Won’t Power On, Inspect the Ducts
Did you know that blocked or obstructed ducts could be the reason your furnace isn’t working properly? When airflow is hindered, your furnace senses something is off and may shut down as a precaution. Imagine this: a stray object accidentally falls into the ductwork, and suddenly your furnace goes into safety mode, refusing to turn on! Keep those ducts clear to ensure your furnace stays in tip-top shape!
Some furnaces are designed with a safety mechanism that triggers a response to prevent carbon monoxide poisoning in your home. While specific conditions need to align for this to happen, your safety is always the top priority. So, when faced with an obstruction, taking swift action to resolve it is the smartest move you can make! Your peace of mind is worth it!
If You Have a Furnace That Won’t Power On, Inspect the Drain Pan
Modern furnaces come packed with impressive safety features! One important element is the drain pan, which collects excess moisture. If it fills up, it can trigger a safety switch that temporarily halts the furnace operation. If you’re still facing issues at this point, take a moment to check the drain pan—typically located beneath the furnace. If it’s full of water, carefully empty it out and get your furnace back on track!
If you’ve noticed your drain pan filling up often, it could signal a recurring issue with your HVAC system’s drainage. Don’t let that worry linger—it’s time to reach out and let us help!

Facing a furnace that won’t turn on can be super frustrating! Thankfully, this common issue is usually fixable with some straightforward troubleshooting.
