DIY Furnace Troubleshooting03/06/2015 One of the most critical parts of the winter is staying snug and warm. Of course, staying comfortable is vital throughout the year, but during the chilly season it is even more essential. Winters in Baltimore are erratic and the coldest days can often spring up on us, sometimes when your furnace is unprepared. So, before you ask a specialized technician, here are a few things you can check first: Check your filter – unclean filters are one of the most common causes of sudden furnace failures. Air has a more difficult time passing through filters once they are dusty or dirty, causing the system to switch off sometimes. The older the furnace, the more difficult it might be to detect the problem, while newer furnaces are designed to pick up on clogged and dirty filters before further issues arise. Swapping furnace filters every month or so can ward off these issues and keep you warm. See if your batteries are weak or dead – keep constant tabs on your thermostat batteries to make sure that there isn’t a flashing low battery light or marker on your thermostat. If there is, it’s time to swap out the batteries on your thermostat. Ensure that your thermostat is set to “heat” – it can be easy to forget little things like the settings of your thermostat. Double-check this important step, especially if there was a relevant spike in temperature that may have caused you to turn off the “heat” setting. Check your switches – in your home’s circuit breaker panel, discover the breakers that control your furnace: [Ensure|Guarantee|Confirm]48] that the switch is in the On side. If it is Off or in the middle of the two spots, change the breaker to Off and then reset it to On. The switch that seems like a light switch should also be in the On, or Up, spot. It can often be confused as a real light switch, which is why it is usually the problem with furnace troubleshooting. Once it’s back On, the system will only take a few minutes to reboot. Working through these steps is a straightforward and effective way of confirming the productivity of your furnace before you give a call to your Baltimore professional. If there are still problems after you have made it through these steps, you will have a much better idea on how to inform your [[technicians|specialists|experts}69] on what the problem might be.
