Has your furnace suddenly just stopped working? There may be a number of different reasons why a furnace will suddenly just stop working. Some of these reasons may be for simple causes which can be corrected without calling up an HVAC service. Hal Mechanical would like to walk you through the basics, and help you troubleshoot and correct the reason as to why your furnace is not starting up. At the end of these steps, if it still will not start, then you have a bigger problem that will require an HVAC technician. When your furnace fails to start up, there are steps you can take to see if you can get the furnace running again. Follow these steps to help troubleshoot and possibly get your furnace up and running.
Check Furnace Circuit Breakers
You first step to determine why your furnace suddenly stopped working is to check the breakers. Sometimes the breakers to the furnace may be tripped. Even a gas furnace requires some power to start up the furnace. To restore your furnace, it may be as simple as resetting a breaker. However, it is not very common for the furnace breaker to trip. If it did, then this may be a sign of a problem such as overheating. If the breaker did trip, monitor your furnace and if it trips again have the furnace inspected by a professional.
Check Thermostat Settings
Another component to check is the thermostat. The thermostat may have been shut off inadvertently or its setting has been adjusted. Things happen, how is often the question. Therefore, if your furnace is not starting up the problem may be the thermostat. In some cases the thermostat may develop a malfunction and need to be replaced. However, that is not very common.
Change or Clean Dirty Air Filters
A furnace may fail to start due to dirty filters. You will want to check the intake filter which should be changed out about every four weeks. However, there is another filter that is often forgotten. The furnace has it’s own filter that can also become so dirty it clogs up the heating system. Check your furnace’s filter and make sure the filters aren’t the reason why your furnace will not start.
Inspect Furnace Pilot Light
One reason why the furnace may have failed to start is that the pilot light may have gone out. The pilot light is a small blue flame that helps to heat up the burners. When the pilot light goes out you can attempt to relight the pilot light. If the pilot fails to relight, this can point to a gas or fuel flow problem which is why the pilot light went out, and why the furnace will not start up.
