DIY Furnace Troubleshooting03/06/2015 One of the most critical parts of the winter is staying comfortable and warm. Of course, staying comfortable is important throughout the year, but during the winter it is even more necessary. Winters in Crystal Lake are erratic and the frostiest days can often appear on us, sometimes when your furnace is ill-equipped. So, before you call in a professional technician, here are a few things you can inspect first: Check your filter – unclean filters are one of the most universal causes of unexpected furnace failures. Air has a more challenging time traveling through filters once they are filthy or dirty, causing the system to shut off sometimes. The older the furnace, the trickier it might be to detect the problem, while newer furnaces are meant to point out clogged and dirty filters before further issues arise. Swapping furnace filters every month or so can prevent these problems and keep you comfy. See if your batteries are weak or dead – keep constant tabs on your thermostat batteries to guarantee that there isn’t a flashing low battery light or sign on your thermostat. If there is, it’s time to replace out the batteries on your thermostat. Ensure that your thermostat is set to “heat” – it can be easy to forget small things like the settings of your thermostat. Verify this important step, especially if there was a new rise in temperature that may have caused you to switch 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 position. If it is Off or in the middle of the two positions, cycle 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, spot. It can often be mistaken for a real light switch, which is why it is usually the difficulty with furnace troubleshooting. Once it’s back On, the system will only take a few minutes to reboot. Going through these steps is a simple and effective way of checking the effectiveness of your furnace before you give a call to your Crystal Lake technician. If there are still difficulties after you have worked through these steps, you will have a much greater idea on how to inform your [[technicians|specialists|experts}69] on what the issue might be.
