DIY Furnace Troubleshooting03/06/2015 One of the most important parts of the winter is staying snug and warm. Of course, staying comfortable is important throughout the year, but during the winter it is even more crucial. Winters in Rocky Mount are always changing and the frostiest days can often appear on us, sometimes when your furnace is unprepared. So, before you find a professional technician, here are a few things you can examine first: Check your filter – unclean filters are one of the most common causes of unforeseen furnace failures. Air has a harder time passing through filters once they are filthy or dirty, causing the system to switch off often times. The older the furnace, the trickier it might be to detect the problem, while newer furnaces are meant to pick up on clogged and dirty filters before further problems arise. Replacing furnace filters every month or so can counteract these problems and keep you comfortable. 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 overlook small things like the settings of your thermostat. Verify this vital step, especially if there was a relevant spike in temperature that may have caused you to switch off the “heat” setting. Check your switches – in your home’s circuit breaker panel, find 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 positions, turn the breaker to Off and then reset it to On. The switch that looks like a light switch should also be in the On, or Up, side. It can often be misidentified 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 require a few minutes to reboot. Walking through these steps is an easy and effective way of checking the efficiency of your furnace before you make a call to your Rocky Mount expert. If there are still difficulties after you have worked through these steps, you will have a much better idea on how to notify your [[technicians|specialists|experts}69] on what the issue might be.
