How to Keep Your Electric Heater Running All Winter Long

Electric furnaces can be expensive to run, even with low-cost electricity in most parts of the country. The main reason is that electric furnaces are programmed to cycle on and off frequently to maintain an even temperature in your home. This saves energy when it’s cold outside, but it might cause you problems if your furnace does not have a “furnace sleep” program which allows the heater to turn itself completely off at times during the night when the house is unoccupied.

If this is happening every once in a while, there may not be much cause for concern (unless you’re paying for power you’re not using but it could pose some serious problems if it is happening regularly. This problem can be caused by a number of different things, but we’ll talk about how to find and fix them below:

Why Does My Furnace Cycle On And Off?

There are several reasons why your electric furnace may turn on and off frequently:

  • The temperature setting on your thermostat may be set too high; lower the temperature and see if that helps.
  • You might have a programmable thermostat that allows you to preheat or cool down the house at certain times of day (this could be useful if you like waking up to a warm home). If this is the case, make sure your “heating” periods take place only when the house will actually need heat.
  • The thermostat might be faulty. If it’s readjusting the temperature every few minutes, or even randomly turning your heat off, you may need to replace it.
  • You may have a furnace which is meant to shut down automatically if its internal components (like filters) get too dirty; see if any lights are on and make sure everything looks like it’s working properly.
  • If the problem just started recently, there may have been a power surge in your area that has broken something within your heater.

How Do I Know What Is Causing The Problem?

There are several signs that will indicate what the problem with your electric heating system is:

  • If nothing happens when you turn on the thermostat, even if the temperature is set low, you may have a broken thermostat.
  • If the heater turns on and immediately shuts back off again, or if your house’s temperature doesn’t change when you adjust it but other appliances in your home start to get colder/hotter, the problem might be with your thermostat.
  • Intermittent problems can be caused by issues with belts, switches and other components which should be checked out by a professional. These problems often happen because of a power surge that damages something within the system.
  • Dusty air causes more frequent cycling due to increased strain on internal components; consider buying an air purifier for better performance.
  • If none of these issues seem to be the problem, you will probably need to contact a professional.

How Can I Fix The Problem?

Depending on the nature of the problem, there are several options for fixing it:

  • If your thermostat is faulty, consider buying a new one or asking. If you can replace it yourself (if you know what to do). And if not, call a technician.
  • If your furnace turns off because its filters are dirty. Make sure to regularly clean them or change them out if necessary. Furnaces that have coils that need to be cleaned manually should only be handled by professionals. Unless you understand how to take care of this yourself. Otherwise, call around for prices on having someone else takes care of this for you.
  • Make sure to check your thermostat’s batteries and replace them accordingly.
  • If you’re sure none of these issues are the problem, it should be safe to say that there is something faulty with your furnace. Call around for a technician who deals in electric furnaces and get an estimate on what it will cost to make this issue go away.


Electric furnaces can be a great source of heat for homes and businesses, especially when oil is scarce or expensive. However, they can also be problematic due to their tendency to turn on and off frequently. As the sensors, they use to gauge temperature become dirty over time.

Often, these issues come from simple problems like dust accumulation or broken thermostats. Rather than more complicated issues with components such as switches. There are several steps that one can take in order to identify and fix these problems: checking your home’s settings. Replacing any faulty parts, and looking into potential power surges. That may have damaged something within your heating system. If none of these things work, contacting a professional usually does the trick!
