Furnaces have a multitude of fuses, and each fuse is important in its own way. And although a blown fuse can be a minor issue that’s easy to fix, there could also be an underlying problem that’s causing it to blow. That issue could be something that needs to be checked out as soon as possible. To identify some common causes for blown fuses, we at Hilliard-Dublin Heating & Air compiled the following list of things that could be wrong with your unit and your fuses.
Possible Reasons For A Furnace That is Blowing Fuses in Your Franklin County, Ohio, home
Wire Damage Or Short Circuits
One probable reason for a furnace that blows a lot of fuses due to the wiring. If the wires are loose or poorly connected, it will cause your furnace to short circuit. Inspecting the wiring in your home is the best method for discovering if this is the cause of your issues. Are the wires damaged? Don’t worry, if you haven’t ever had your furnace inspected, it is an easy, painless process that we at Hilliard-Dublin Heating & Air would be happy to do. Our contact information is below.
Thermostat Wires
If your home’s thermostat is enclosed in a metal frame, it can blow fuses if they touch the metal or have close contact with it. Additionally, it can cause an issue in which the voltage is too high for the wires to manage. If the wires are unable to maintain the voltage, it can blow the control board, and make it so the draft inducer will not start. If this happens, nothing will be able to operate, and your unit will stay off until it is fixed.
Clogged Filter
To maintain a clean and efficient unit, you should check your furnace’s air filter at least every one to three months, depending on the size of your home and what’s inside. If you don’t, the dust, dirt, and debris will build up within your unit and will clog the blower motor, which could shut it down. While the blower motor is clogged up, it can cause fuses to blow because it has to work hard to try to operate. The fuse is also attempting to run, and because it is unable, this increases the chances of a furnace fire. To keep your family safe and warm, and to prevent fuses from blowing, replace your furnace’s air filter frequently, and have one of our friendly technicians come clean out your furnace at least once each year.
Water Leaks
Having an old leak in your furnace is not uncommon. However, if you do not take care of it, it can damage your unit. So if you find any leaks, having a professional look at them is a must. Some homeowners wait to see if the leak becomes worse, hoping it goes away. Unfortunately, they rarely go away on their own, and if you wait too long to call, the issue usually gets worse and leads to bigger and more expensive problems.
So if there’s any sort of issue with water leaking from your furnace, don’t wait to call us. Water contact can create a short circuit and blow fuses.
Failing Valve
Failing valves only apply to homeowners with gas heated furnaces. Your safe valve needs to be able to open and close when necessary. If clogged, the failing valve might be forcing too much heat out or keeping too much heat inside. If it overheats, it can also cause a fire. For this reason, it is essential to keep dust out of your furnace to keep your home and family safe.
