DIY Furnace Troubleshooting03/06/2015 One of the most important parts of the winter is staying snug and warm. Of course, staying comfortable is critical throughout the year, but during the winter it is even more crucial. Winters in Denver are erratic and the coldest days can often appear on us, sometimes when your furnace is not ready. So, before you ask an expert technician, here are a few things you can check first: Check your filter – unclean filters are one of the most universal causes of unexpected furnace failures. Air has a more challenging time floating through filters once they are filthy or dirty, causing the system to switch off sometimes. The older the furnace, the harder it might be to find the problem, while newer furnaces are designed to pick up on clogged and dirty filters before further issues arise. Replacing furnace filters every month or so can prevent these issues and keep you comfortable. See if your batteries are weak or dead – keep continuous tabs on your thermostat batteries to make sure that there isn’t a flashing low battery light or sign on your thermostat. If there is, it’s time to switch out the batteries on your thermostat. Ensure that your thermostat is set to “heat” – it can be easy to neglect minor things like the settings of your thermostat. Insure this important step, especially if there was a new 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 run 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 sides, change 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 definitely be confused as a real light switch, which is why it is frequently the problem with furnace troubleshooting. Once it’s back On, the system will only take a few minutes to reboot. Walking through these steps is a simple and effective way of confirming the efficiency of your furnace before you give a call to your Denver expert. If there are still issues after you have worked through these steps, you will have a much greater idea on how to notify your [[technicians|specialists|experts}69] on what the problem might be.
