The question of whether or not your heater is experiencing electrical issues honestly depends on how much of your system uses electricity. If you’re using an entirely electrical heater, then the chances of any heating issues being electrical are pretty high. If you use a wood-burning furnace, the chances are significantly lower. For the purposes of this article, however, let’s just assume that you’re using a standard forced air system like a gas-burning furnace. Let’s examine the ways in which you can tell that a problem in that kind of system is electrical.
Regardless of what is wrong with your heating system, the very first thing you should check is the thermostat. The thermostat is the core of your heating system, and about as close to a brain as it can get in terms of control function. If the thermostat malfunctions, the whole system often malfunctions.
Check the display on your thermostat and see if everything being displayed is correct. If the settings and temperature all appear to be right, then that’s a good sign. However, it is still possible that the electrical connections between the thermostat and the heating system have weakened somehow. You won’t be able to confirm that one way or another on your own. You’ll need to have a professional HVAC technician to open up the thermostat in order to confirm any issues inside it.
Many older combustion systems made use of a standing pilot light, which was a gas powered flame that burned continuously underneath the system and served as the ignition source. More modern systems, however, tend to use electrical ignition systems that are more efficient. If you know that your heating system uses one of these modern electrical ignition pilot lights, check to see if the system is actually attempting ignition. If an electrode or heating element has burned out, then the system has no way to actually start.
