It’s a dark and cold afternoon. You notice it feels a bit chilly inside, so you dial up the thermostat expecting to feel some heat—except nothing happens. Oh no! When your furnace stops working, especially during the chilly months in Indiana, it can be a source of significant discomfort and concern.
But what do you do when your furnace stops working? It starts by taking the steps to take to troubleshoot and potentially resolve the problem—or to know when it’s time to call in a professional. This guide will walk you through the essential steps to take when your furnace stops working, ensuring you stay warm and safe during Indiana’s colder seasons.
Start with the simplest solution by checking your thermostat. Make sure it’s set to “heat” and the temperature is set higher than the current room temperature.
You’ll also want to consider the type of thermostat you have. If it’s a programmable thermostat, ensure that it’s set correctly for the day and time. Sometimes, incorrect programming can prevent the furnace from turning on when you need it.
Battery replacement is another simple fix to consider. Many modern thermostats are battery-operated and may malfunction or not read temperatures accurately if the batteries are low. If the screen is blank or displaying a low-battery symbol, replace the batteries.
Finally, if your thermostat is a smart or Wi-Fi-connected model, troubleshoot that it’s properly connected to your home network. Loss of connectivity can disrupt the control over your heating system
Sometimes, a simple adjustment or battery replacement is all that’s needed.
Can a dirty filter stop your furnace from working? Absolutely! A dirty or clogged filter is a common culprit for furnace problems.
Over time, furnace filters accumulate dust, pet hair, and other debris, which can significantly impede airflow. This restriction of air movement can lead to several issues:
The good news is that checking and replacing your furnace filter is a straightforward task. The filter is usually located near the blower unit and should slide out easily. When replacing the filter, ensure it’s the correct size and type for your furnace, and that it’s installed in the correct orientation (look for arrows on the filter’s frame indicating airflow direction).
Blocked or closed vents can lead to system imbalances that not only affect the comfort of your home but can also strain your furnace. Here’s what you need to do to make sure that you have good airflow:
Sometimes, the issue could be as straightforward as a tripped circuit breaker. Check your home’s electrical panel and reset the furnace’s circuit breaker if necessary. If the problem persists, call us to diagnose and repair the issue.
The color of the furnace flame can indicate various issues. It should be blue with a small yellow tip. If it’s mostly yellow, it could indicate a ventilation problem, which requires professional attention.
If your furnace is older, its efficiency could be diminishing. Older furnaces might need more frequent repairs or might be nearing the end of their lifecycle. Keep in mind that your furnace will likely last around 20 years.
If the above steps don’t resolve the issue, or if you’re uncomfortable performing any of these checks, it’s time to call us at Area Sheet Metal Heating + Cooling. We can diagnose and fix more complex problems, making sure that your furnace operates safely and efficiently.
