You do not want your furnace to ever break down, especially during one of the coldest days of the year. It may happen during your time as a homeowner, and when this happens, you should know what to do, as you may be able to make the repair yourself, especially if it's something minor and simple. Read on for three things to check before calling out a furnace repair technician. Before doing any type of work on your furnace, always turn the power and gas off to your system to prevent injury.
1. Check The Air Filter
The air filter can give you all types of problems, especially if it's full of debris, dust and dander. Pull out the air filter and remove it from the housing. Inspect it thoroughly and check to see if it's full. You can hold it up to the light to see if it's full - if you don't see any light through it, then you know that it may need to be changed. A full filter is also going to feel heavier. Remove the old, dirty filter and replace it with a brand new one. Install the filter the same way you removed the old one. You'll have to hit the reset switch on your furnace in order to turn it back on.
2. Check The Flame Sensor
If the flame sensor is too dirty, it will shut your furnace off. You need to find the flame sensor and inspect it to see if it's dirty. Use a fine-grit piece of sandpaper and wipe it across the flame sensor to clean off any of the grime. Once it's clean, you'll have to hit the reset button on your furnace.
3. Check Inside The Furnace
The inside of your furnace can accumulate with dirt, dust and dander, which can cause your furnace to work improperly. Turn off your furnace and inspect inside the main panel. If you see a lot of debris and dander, use a shop vacuum to clean out the interior as much as possible. Clean up where you can reach with the vacuum extension hose, but try not to get too close to the motor. When finished, close the panel and turn it back on to see if this helped get your furnace working properly again.
Before you call a professional furnace repair technician, check the above first to see if they helped to repair your furnace. If your furnace is still not working properly, call a professional for help. For more information, contact companies like Washam Plumbing Heating & Air Conditioning.
