Dealing with a malfunctioning gas furnace can be a real downer, but fear not! Every problem has a reason and, more importantly, a solution. In this article, we’re diving into ways to troubleshoot your gas furnace to get it back on track and keep your home comfortable. Let’s get into it!
A Troubleshooting Guide For Your Gas Furnace
1. Check The Fan
Ensuring the efficient operation of your gas furnace begins with the proper functioning of its crucial component – the fan.
The thermostat is the control center for your heating system, so head over to the thermostat and ensure the power is turned on by turning the fan to the ON position on your thermostat. If something is still off, check to see if the circuit breakers on the electrical panel have been tripped to the OFF position. Additionally, verify that the SSU (Service Switching Unit) light switch on the gray box near the furnace is also set to ON to supply power to your furnace.
2. Check The Settings
If your gas furnace is not delivering the expected heat, the issue could be as simple as forgetting to set your thermostat in the HEAT position. So, what you can do is simply double-check that the settings are in the correct position. Also, while you’re at it, see if your thermostat’s temperature setting is higher than your indoor temperature. If the setting is too low, the furnace may not activate.
3. Check The Air Filter
The next step in troubleshooting your gas furnace is to check the air filter. This is a common culprit behind many heating issues. A clean air filter is vital for optimal furnace operation, as a dirty or clogged filter can impede airflow, reducing effectiveness or even causing your gas furnace to shut down. If your air filter is dirty, it’s essential to clean or replace it.
You’d also want to ensure the air registers (supply or return ducts) around the house are plugged in. Like air filters, if these air registers are blocked, it can disrupt airflow, make your furnace work harder, and potentially lead to overheating issues.
If you need more clarification about the condition of your air filter and air registers, it’s advisable to have a professional inspect them for you.
