Potential Failure Points In Your Electric Furnace

Nothing lasts forever--but with the right maintenance, your electric furnace can last for several decades. If you want to extend your furnace's life, you should know where the most likely points of failure are, then repair or replace those components before they cause an outage. With electric furnaces, most failures are due to an electrical problem, but that doesn't mean the electric components are the only things you need to watch out for. 

Mechanical Failures

Moving parts are the bane of most household appliances, especially large ones like your furnace. Of critical importance in this case is the fan and its motor, as without the fan your furnace will do little more than heat itself and not your home. While your fan can be replaced, it's better to avoid the hassle by keeping it functional for as long as possible.

Watch for signs that your fan motor is working harder than normal, such as excess noise or excess heat. These problems usually result from drag on the drive rod that supports the fan blades. If the blades of the fan become coated in dust or debris, this can also push your fan out of balance, which results in excess drag on the motor that may cripple your furnace. Cleaning out the area around your fan and its motor will help prevent premature breakdowns and keep the furnace running.

Electrical Failures

By far the most common type of failure in an electric furnace, electrical failures can range from faulty wiring to corrosion, or they may simply mean a damaged heating element. If one of your electrical components fails, begin your investigation into the problem by shutting off the breaker, both at your electrical box and on the furnace itself.

With time, any wiring will become worn, and the humid air in moist climates can compound that problem. Look over the wiring for signs of wear or discoloration, such as from exposure to heat or moisture. You should look for similar problems on your furnace's heating element, but in this case signs of discoloration are often an early warning that the element itself is close to shorting out or fracturing and should be replaced.

You can probably handle simple cleanings and replacements on your own, but any component should be replaced by a professional. This will ensure that the new part is compatible with the old furnace and functions correctly. If you need any help with your electric furnace, get in touch with HVAC professionals at a company like Comfort Heating & Air Conditioning, LLC.

About Me

The Comfort of Home

When I married my amazing husband ten years ago, I moved into the brick, ranch home he already owned. Immediately, I was thankful that the house was equipped with a central heating and air conditioning unit. This once efficient system kept me cool during the hot summer days. It also allowed me to remain warm in my home during the cold winter nights. Now, our air conditioning unit is twenty years old. Because of its age, the system has started to malfunction. Recently, my husband contacted an HVAC contractor about installing a new system at our home. This kind technician patched our old system to give us time to contemplate what type of new unit we want. On this blog, I hope you will discover the ways an HVAC contractor can help you continue to enjoy the comfort of your home.
