Whenever your gas furnace stops pumping out the heat, try to sort and troubleshoot the problem yourself by following the pros’ five furnace troubleshooting tips. You can also call a furnace repair professional to fix the issues.
Circuit breaker
Check your circuit breaker panel at home and look for a circuit that controls the furnace. If it is in the off position or the middle, just put it back to the on position. The best way to do this is to throw the switch up to the off position and then throw it back to the on position. Ensure the correct labeling of your appliances to the individual circuit breakers in the circuit breaker panel.
Confirm that the furnace gets power
You must check to see whether your furnace is getting electricity. Many thermostats have a switch for the fan that shows whether it is on or auto. Make sure to throw the switch to the on position. If the fan switches on, then you have solved the problem. If the fan does not come on, your furnace has other issues. Get professional help to troubleshoot the issue ASAP.
Battery check
Many thermostats are usually wired to the house’s electrical system. Some use batteries instead. Those thermostats that use batteries will flash to show low battery. Replace the batteries, and you will have fixed the problem completely. However, we have found that most people do not check the signal of the battery symbol on the thermostat.
Furnace filter
One of the most common problems that furnace owners face is filter-related failures. This happens more often because furnaces owners forget to check the filters after regular intervals. Filters help clean in cleaning the air that is entering the furnace. A clogged or dirty filter will not allow air to flow freely. This can cause heating and pressure to build up in the furnace.
However, the newer furnaces are more efficient, especially since they are practically sensitive to this problem, thereby shutting down the entire system well before the clogged filter causes any more trouble. In furnaces that do not have this feature, they will run at a significantly reduced efficiency and will not produce enough heat.
Set the thermostat to heat
Although mentioning that you should be sure to set the thermostat to heat may sound foolish, you will be shocked to know that people don’t usually have their thermostat set correctly. The first thing to do to troubleshoot your furnace is to check that the thermostat has been set correctly. Many thermostats are required to be set to the heat mode manually. It is only natural that this switch is turned off for many reasons, such as during dusting or simply accidentally switching it the other way.
Conclusion
From what we have seen in the above five furnace troubleshooting tips from the pros, it is easy now to identify the common problems and how to try to troubleshoot them yourself before actually calling any professional.
