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 winter it is even more necessary. Winters in Carlsbad are always changing and the chilliest days can often appear on us, sometimes when your furnace is not ready. So, before you call in a specialized technician, here are a few things you can examine first: Check your filter – grimy filters are one of the most widespread causes of unforeseen furnace failures. Air has a more challenging time traveling through filters once they are filthy or dirty, causing the system to switch off on some occasions. 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 troubles arise. Replacing furnace filters every month or so can counteract these troubles 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 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 small things like the settings of your thermostat. Verify this vital step, especially if there was a recent rise in temperature that may have caused you to change the “heat” setting. Check your switches – in your home’s circuit breaker panel, find the breakers that run 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 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 definitely be mistaken for a real light switch, which is why it is often the issue with furnace troubleshooting. Once it’s back On, the system will only need a few minutes to reboot. Working through these steps is an easy and effective way of confirming the efficiency of your furnace before you give a call to your Carlsbad expert. If there are still issues 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 trouble might be.
