5 of the most common reasons why your gas furnace won’t start
Are you wondering, “why won’t my gas furnace turn on when I need it to?”. Here are some of the most common things that can stop your furnace from starting:
Check the thermostat to make sure it’s set to “heat”
When troubleshooting your furnace, it’s important to rule out each of these potential causes. Otherwise, you could end up spending money on unnecessary repairs.
One of the most common reasons why your gas furnace won’t start is because the thermostat is set to “cool” instead of “heat.” This is an easy fix – simply turn the switch to “heat” and see if that solves the problem. If not, the next step is to check for a clogged burner.
A build-up of dust and debris can prevent the burner from igniting properly. The last thing you should do is attempt to clean the burner yourself – this is a job best left to a professional.
If the burner looks clean, there may be issues with your gas line. A broken or ruptured gas line will prevent any gas from reaching the furnace, so it’s important to have this checked by a trained technician.
By ruling out each of these potential problems, you can quickly get your furnace up and running again.
Ensure that the furnace’s switch is in the “on” position
One of the common reasons why your gas furnace won’t start is because the furnace switch is not in the “on” position. Before doing anything else, make sure that the switch is turned to the right position. If it is, then check to see if there is an unexpected power outage in your area. If there is, then you will need to wait until the power comes back on before you can use your furnace.
Inspect the furnace filter and replace if necessary
One of the most common reasons why your gas furnace won’t start is because the furnace filter is clogged. The filter traps dust, dirt, and other particles that can accumulate over time, preventing them from entering the furnace. If the filter becomes too full, it can restrict airflow and cause the unit to suddenly overheat.
As a result, the furnace may shut down automatically as a safety measure. To prevent this from happening, it’s important to inspect the furnace filter regularly and replace it if necessary.
Check that there is power going to the furnace by testing the breaker box
One of the most common reasons a gas furnace won’t start is because there is no power going to the unit. This can be easily checked by testing the breaker box to see if the switch for the furnace is turned on. If it is turned off, simply flip the switch and wait a few minutes to see if the furnace turns on. If there is still no power, you may need to check the fuse box for a blown fuse.
Call a technician if you’ve checked all of these things and your furnace still isn’t working
If your furnace still isn’t working after you’ve tried all the troubleshooting tips, it’s time to call a technician. While it’s possible to DIY some furnace repairs, it’s generally best to leave the more complex repairs to the professionals.
A qualified technician will be able to quickly diagnose the problem and make the necessary repairs. They will also be able to properly test your furnace to ensure that it is safe and efficient.
So if you’re having trouble with your furnace, don’t hesitate to call a technician for help.
