furnace electrical failure

Your heating system broke down in the middle of the coldest night of the season. Oh no! Before you call a professional for furnace repair, you need to know what caused your system trouble to begin with. If it’s a result of bad electrical connections, you definitely need to know what went wrong, even it just comes down to a blown fuse. The clock is ticking, and the weather isn’t getting any warmer.

Here, we’ll explain what kinds of electrical problems can sink your furnace’s performance so you can call for help before you’re left without heat at all.

The Importance of Furnace Maintenance

Your furnace has a big job. It’s tasked with keeping your family warm and comfortable during the winter months. With proper maintenance, your furnace will continue to heat your home efficiently for many years to come, helping you save money on utility bills while providing a steady flow of heat throughout your home. If left unattended to, however, your furnace could leave you facing costly repair or replacement bills. Improperly maintained furnaces often have shorter life spans and increased safety hazards. Not to mention, they can leave homeowners without heat when they need it most.

10 Common Causes of Furnace Failure

Wondering what leads to furnace electrical failure? The following are 10 common problems incurred by improperly maintained furnaces:

  1. Clogged filter. Dirty or clogged filters reduce airflow, which ultimately forces the furnace to work harder to circulate air. Clogged filters can also damage the limit switch, which is responsible for controlling the fan. Be sure to clean your filters regularly, or simply swap them out for new ones.
  2. Loose wiring. When your furnace is running, it causes a certain amount of vibrations. Over time, these vibrations can cause internal wiring to become loose, which can eventually lead to an electrical short. A single loose wire can be difficult to find, so it’s best to have regular tune-ups to ensure your wiring stays tightly connected.
  3. Incorrect fuses. It’s essential to equip your furnace with fuses large enough to handle the capacity of your heating system. If a fuse is too small, it will almost assuredly result in electrical problems.
  4. Dirty fuses. Dirt and soot are normal parts of your furnace’s daily life, but it’s important not to let these elements build up. Excessive grime can impede your fuses from being able to connect to the electrical components. To ensure sustained connectivity, be sure to keep your fuses cleaned as part of regular, ongoing maintenance.
  5. Exposure to water. Water and electricity don’t mix. If your furnace is tucked away in a damp place or located near any water leaks, an electrical failure is likely in your future. Seal any leaks to remove excessive moisture that could cause your furnace’s electrical system to fail.
  6. Transformer failure.  Transformers are responsible for converting energy into the correct voltage necessary to run your furnace’s controls, ignition, and timer. If your transformer isn’t functioning properly, it won’t support your home’s electrical system correctly. If you’re unsure about your transformer’s capacity, it’s best to contact an HVAC professional as soon as possible.
  7. Faulty starting capacitor. The capacitor is to your furnace as the starter is to your car. It’s necessary to get the system started. If your capacitor is on the fritz, it may cause intermittent electrical problems. Faulty capacitors can be replaced fairly inexpensively, which should solve the problem.
  8. Faulty blower motor. Motors require a good amount of energy. If your blower motor is failing, it will put additional strain on your power source, eventually leading to an electrical short. A faulty blower motor should be replaced by an HVAC expert.
  9. Failed valves. Natural gas or propane furnaces are equipped with valves that regulate gas pressure. If a valve is malfunctioning and unable to open and close properly, the pressure regulators will not work properly. This can cause the malfunctioning valve to heat up, resulting in an electrical short and a blown fuse.
  10. Thermostat control wiring problems. There are plenty of wires surrounding your furnace, and if someone isn’t careful, he or she could inadvertently move or disconnect the wires that interact with your thermostat. The control board of your furnace has a separate fuse that keeps it from getting too hot. Beyond the surface lies your furnace’s wire frame, which can easily be the culprit for blown fuses and short circuits, particularly if someone erroneously found their way to this thermostat control system and relocated some of the wiring.

When it comes to your home heating system, it’s always better to be proactive, rather than reactive. Furnace electrical failure can leave you out in the cold when you need heat the most. To ensure your heating system stays healthy and happy, schedule regular furnace tune-ups with HVAC professionals.

Furnace 101: Everything You Should Know As a Savvy Homeowner 

Furnace 101: Everything You Should Know As a Savvy Homeowner 

  • Heating
  • Miscellaneous
furnace

The most common source of home heating in the United States is the furnace. But most people don’t understand how this amazing piece of machinery really works.  It’s either out in the garage or in the basement, out of sight and out of mind.

However, if you’re a homeowner, it is important to understand how this heating system works. Why? If your furnace is displaying issues, it’s better to recognize there is a problem and have a general idea of what may be causing the furnace problem rather than have the issue go unnoticed or ignored.  The results could be dangerous and extremely expensive in labor, repairs, replacement and other costs.  

Benefits of Understanding How Your Furnace Works

Homeowners who understand how their furnace works will experience many long-term benefits, including:

  • A longer lasting heating system:  When a homeowner understands how their furnace works, the chances of noticing a problem right away increases.  The more a furnace is inspected and maintained, the longer it will last.  And since this is an expensive piece of equipment for your home, you will want to avoid having to replace it before its time.  
  • Greater energy efficiency:  A furnace that is working at it’s best will produce heat in your home with ease, making your property greener. However, if your furnace struggles to work, it will take more and more energy to produce heat and in the long run, this will cost your more money and put unnecessary stress on the furnace system.  
  • Quicker reaction time to problems: The faster you notice a problem with your furnace, the quicker you can get someone to take a look at it.  This will prevent any hiccups in your heating. The last thing you want is to be stuck in a cold house where the heat isn’t working.  
  • Improved home comfort:  When your furnace works the way it is supposed to, you can be guaranteed a warm, comfortable home all season long.  By paying attention to your furnace and how it is working, you can avoid any major problems during the colder months.  

How Your Furnace Works

The furnace is a remarkable piece of machinery that is responsible for you keeping you and your family warm as the temperature drops outside.  To understand how it does this, we have broken down the process into steps.  Essentially, a furnace heats a home using the six step process outlined here:

 

  • Step 1:  The thermostat senses the temperature in the home.  If the temperature is too low, according to the temperature you set on the thermostat, the furnace burner turns itself on. Sometimes you will hear a clicking sound when this happens.  
  • Step 2:  Once the burner is on, it will continue to run until the temperature set on the thermostat is reached and maintained.  Your furnace is smart and can sense the temperature in the house at all times – as long as it is working correctly.  
  • Step 3:  Now that the furnace is running, what is actually happening inside the device?  The heat produced by the burner circulates inside the heat exchanger, which then transfers combustion gasses to the flue vent connector and then to a building chimney where they are vented outside. These gases belong outside because if they are contained in a small space, such as your home, they produce negative health effects such as eye and respiratory irritation, coughing, headaches, tiredness and dizziness.  

The following last steps are straightforward and explain how a furnace turns a cold house into a place of warmth after getting rid of combustion gases. 

  • Step 4:  The furnace also works as an air filter during this next step.  Using an electric fan, the furnace pulls in fresh, cold air and filters it so that you won’t be breathing in dust and other harmful particles.  Not only that, but the air must be clean when running through the system to keep the machinery in tip top shape. For this reason, it is Important to replace filters every few months.  
  • Step 5:  At this point, the filtered air passes into the plenum, a small, enclosed space.  The hot air rises from the heat exchanger and then circulates throughout the home via air ducts. This heating process continues over and over until the desired temperature is created and maintained throughout the home.  
  • Step 6:  The furnace regulates itself with a blower fan.  The fan is able to turn on and off to regulate the amount of heat produced.  System size is important at this stage.  If a furnace is too large for the area it intends to heat, it will short-cycle.  If it is too small, the furnace will constantly run during the colder months and  in turn use a lot more energy to heat a home than should be necessary.  

As a homeowner, it is your job to understand how something as important as a heater works to heat your home.  Being able to recognize the steps a heater takes to produce heat will help you understand if there is a problem and get it taken care of right away.

How to Stay Warm During a Heating System Breakdown

How to Stay Warm During a Heating System Breakdown

heating breakdown

If you have ever experienced a heating system breakdown in the midst of winter, you know how miserably cold it can get in your house in a short period of time. So you make the call for emergency heating repair and get help on its way. In the meantime, you still need to stay warm while your home slowly tries to turn into an ice castle around you. Fortunately, there are several different things you can do to keep your home warm, even if your heating system is limping along or not working at all. While you may not be as comfortable as you otherwise would, you can at least feel a little better while you wait.

Don’t Wait or It Could Get Worse

When your heat goes out, make the call right away to get someone headed to your home for heating system repairs. If you leave things alone for too long, you could end up with frozen pipes and other problems. You also won’t be comfortable, and that could increase the chances of feeling depressed, unhappy, or even getting sick. Rather than suffering in silence , take comfort in knowing that a service technician has been contacted and is on their way to you as soon as they can get there. If they have a lot of service calls, that could be a few hours. What do you do in the meantime?

Be Proactive for Big Benefits

If you take a proactive stance on your home heating needs, you can find that staying comfortable is more easily achieved. Even when your heating system is struggling, or when it is not working at all, there are ways you can protect yourself and your home against the worst of the chill until a heating technician arrives to get your system up and working again. That can help you eliminate stress and ensure that you will not be spending your time without at least some source of heating that can help you feel better while you are waiting.

Follow These Tips to Stay Warmer While Waiting:

  • Close all doors and windows – When a heating system breaks down, the first thing you want to do is make sure every window and door in your home is tightly shut. That way you reduce the amount of cold air that comes inside and the heat that is already in your house will last longer. 
  • Sealing air leaks in duct systems – If there are any air leaks in your duct systems, seal them off. It is better to have this done beforehand, but that is not always possible. If you can feel air moving, there is a leak somewhere. Finding and blocking it will protect your home and your body temperature.
  • Keep candles handy – Having candles on hand can be very beneficial if your heating is out due to a power outage. But they can also be a good choice when it comes to a heating breakdown. They can easily warm your hands and having them nearby puts off some much-needed heat for the space.
  • Insulate windows – Putting builder’s plastic or another extra surface up in your windows can mean that the cold air from outside does not seep in so much and the warm air in your home is not able to escape as easily. Even double pane windows do not offer complete protection, so add those extra layers.
  • Use your fireplace – If you have a fireplace, either gas, electric, or wood-burning, make use of it. While it will not heat your whole house like your heating system would, it can keep at least one room warm enough to be comfortable while you wait. Then you can avoid the worst of the cold until a heating technician arrives.
  • Use the sun for heat – If the sun is out, make use of it. Open your curtains and blinds on the side of the house where the sun is shining. Allowing the sun to come in the (closed) windows can warm your house up, and make things feel better during a heating system breakdown. Just be sure to keep the blinds or curtains closed if there is not any sunlight, to help hold the heat in as much as possible.

Wear layers of clothing – Dressing warmly is one of the best things you can do if your heating system breaks down. By dressing in layers you not only have more clothing to keep you warm, but layers also trap heat and hold it against your body. That will reduce the chances of you getting too cold, and can make your wait to have heat restored much easier to get through
