Troubleshooting Your Furnace: What to Expect When It Won't Turn On

Posted on: 23 January 2024

When temperatures drop, the last thing you want to deal with is a furnace that won't turn on. It can be frustrating, especially if you have no idea what's going on. But don't worry; there are steps you can take to troubleshoot your furnace. In this guide, we'll explore some of the most common issues that can cause your furnace to stop working and what you can expect when you call a professional for furnace repair.

Check the Thermostat
The first step in troubleshooting your furnace is to check your thermostat. Make sure it's turned on, set to "heat," and the temperature is set high enough to engage the furnace. If that doesn't work, check the batteries. Finally, make sure the thermostat is properly wired to your furnace.

Check the Air Filter
A clogged air filter can cause your furnace to shut down as a safety precaution. Make sure you change your air filter regularly to ensure proper airflow and avoid a potential furnace repair.

Check the Circuit Breaker
It's possible that your furnace may have tripped the circuit breaker when it attempted to turn on. Look for the circuit breaker panel and make sure the breaker for your furnace is in the "on" position. A tripped breaker can be an indication of a more serious electrical problem, like a short circuit.

Check the Ignition System
If your furnace uses gas, there may be a problem with the ignition system. Make sure the gas valve is turned on, and try lighting the pilot light if it's out. If the pilot won't light and you can't hear a clicking sound when you try, you may have a faulty ignition system that requires professional furnace repair.

Call in a Professional
If you've tried all of these steps and your furnace still won't turn on, it's time to call in a professional. A qualified technician can diagnose the problem and perform the necessary furnace repair. Before you hire someone, do your research. Check their credentials, read reviews, and don't be afraid to ask for references.

While no one wants to deal with furnace repair, knowing what to expect when your furnace won't turn on is important. You can troubleshoot common issues by checking the thermostat, air filter, circuit breaker, and ignition system, potentially avoiding a more serious problem. If all else fails, don't hesitate to call in a furnace repair professional. With a bit of knowledge and a qualified technician, your furnace will be running again soon, and you can enjoy a warm and comfortable winter.
