DIY Furnace Troubleshooting03/06/2015 One of the most critical parts of the winter is staying cozy and warm. Of course, staying comfortable is vital throughout the year, but during the chilly season it is even more necessary. Winters in Marshalltown are erratic and the frostiest days can often spring up on us, sometimes when your furnace is not ready. So, before you ask a professional technician, here are a few things you can examine first: Check your filter – unclean filters are one of the most widespread causes of unexpected furnace failures. Air has a more challenging 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 find the problem, while newer furnaces are created to point out clogged and dirty filters before further problems 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 indicator 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 little things like the settings of your thermostat. Double-check this vital step, especially if there was a recent spike in temperature that may have caused you to turn 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 spot. 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 seems like a light switch should also be in the On, or Up, position. It can definitely be mistaken for a real light switch, which is why it is often the problem with furnace troubleshooting. Once it’s back On, the system will only take a few minutes to reboot. Going through these steps is an easy and effective way of checking the efficiency of your furnace before you give a call to your Marshalltown expert. If there are still difficulties after you have made it through these steps, you will have a much wider idea on how to notify your [[technicians|specialists|experts}69] on what the problem might be.
