DIY Furnace Troubleshooting03/06/2015 Maintaining complete home comfort during the winter months is one of the top concerns for a lot of people. Sure, you’d like that to extend year-round, but when winter gets its coldest, it feels a little more essential. The scenario normally unfolds like this: your local Orrville weatherperson is predicting the coldest day of the year and your furnace decides to go out. Now there’s no need to panic and call a furnace technician quite yet. There are a couple things you can check on your own before calling them. Ensure your thermostat is set to “heat” – sure, it sounds obvious, but it’s easy to forget to set your thermostat to the correct setting. Whether it’s an inadvertent change while cleaning or you had an unexpected jump in temperatures for a few days and didn’t need your thermostat, double check your thermostat’s setting. Check your filter – one of the most common causes of furnaces turning off unexpectedly is a dirty filter. When furnace filters get too dirty, air cannot pass through them as effortlessly. The furnace can detect this and will shut off the system. If you have an older furnace, it may not detect the problem and cause an even bigger headache. Newer furnaces have been designed to pick up on this issue and have an easier time shutting the system down before it causes any further issues. Getting in the routine of changing your furnace filter every month can ensure you don’t wake up to a frigid house. Weak or dead batteries – if your thermostat works with batteries, check it to ensure there isn’t a flashing low battery signal or another indicator that it’s time to swap out your batteries. Other thermostats run off of your home’s electrical system and don’t have to worry about this. Check your switches – find your home’s circuit breaker panel and find the breaker that controls your furnace. You should be able to see if it is in the middle position or the Off position. If it is, cycle the breaker to Off and then re-set it back to the On position. If at any point you feel uncomfortable with the circuit breaker panel, please consult your local Orrville dealer or an electrician. The other switch to check looks just like a light switch, which could be the issue. It’s your furnace switch and should be in the Up, or On, position. Because of its semblance to a light switch, it can be easily mistaken for one. Once On, give the furnace a little bit to start up as many systems operate with built-in delays. Following these few steps before contacting your local Orrville technician can help you eliminate the easy things, and if there is still a problem, it allows you to provide pertinent information to the technician if they end up coming out. Troubleshooting your furnace doesn’t have to be tough, but ensuring you stay within your comfort zone is key too. There’s no need to take any risks and potentially do more damage to your furnace, so once you start feeling a little unsure, give your local furnace technician at Daniel's Heating - Cooling & Electric in Orrville a call.
