The last thing you need when the weather begins to become cold is to experience a malfunctioning furnace that won’t turn on. Refusing to turn on, or turning on then immediately turning off is not an uncommon issue with residential furnaces. Oftentimes, there’s a fairly easy solution. Here’s what you should do if you notice that your furnace is not turning on.
A Clogged Air Filter
One of the most common reasons that a furnace may not be turning on is a clogged air filter. It’s advisable to change your furnace filter once every 30 days to ensure it doesn’t become clogged with dirt, dust, and debris. A clogged furnace filter may cause the furnace to overheat or stop working altogether.
A Malfunctioning Thermostat
A malfunctioning thermostat can be a very common culprit in a furnace not turning on. If your thermostat is old, needs to be replaced, or even has dying batteries, you may notice that it’s not communicating properly with your furnace, causing it to turn on and off without reason. If your furnace isn’t turning on, check to see if your thermostat is working properly.
An Issue with the Gas Line
Sometimes a furnace not turning on is indicative of an issue with the gas line. This could be part of your home’s gas line or an issue with the gas company. If you suspect that your furnace isn’t working due to an issue with the gas connection, call your local gas company for assistance.
It’s Time for Furnace Repair or Replacement
Sometimes a furnace that is experiencing a breakdown, or even a furnace that is on its last legs will start refusing to turn on. This could be a sign that it needs repair or even replacement. If you’ve tried these simple troubleshooting steps and they didn’t work, or if you have a very old or inefficient furnace, you may want to consider replacing the system with something more reliable, powerful, and efficient.
