Did you know that your gas furnace has electrical components in it? Well, it should if it was manufactured in the last twenty years. And if it’s older than that, then you might want to get it replaced by a system that does have electrical components.
The truth is that electricity is useful for more than just our computers and television sets. It’s amazing for short, quick jobs that can be done by a circuit. Ignition in a gas furnace is one of those jobs, and pilot lights are quickly being replaced by an electric ignition.
Since furnaces are so common in our area, we thought it would only make sense to talk about some of the electrical malfunctions that can happen inside of them. And, if any of what we’re about to talk about sounds familiar, you can call our team for expert furnace service in Pasco, WA.
The Capacitors Are Acting Up
The capacitors are required for the system to start up and shut down. They’re literally called “stop” and “start” capacitors because that’s all they can really do. In order for an appliance to turn on or off remotely, it needs a capacitor that can signal to the rest of the system that it’s time to turn on.
If your capacitor is worn out or starting to go, you might hear multiple “clicks” while the furnace starts up, meaning it’s not getting the signal with just one. Also, if your furnace runs for a particularly long time without it being needed, it might be due to a failed capacitor that can’t shut the system down properly.
The Ignition Is Faulty
Contrary to popular belief, most gas furnaces these days use electric ignition systems. These are more efficient, safe, and effective than old pilot lights ever were, and they’re a great innovation.
However, just because your furnace has an electrical ignition system doesn’t mean that it’s impervious to issues. Electrical components can fail just like a pilot light, which can then lead to your heating system failing to start up. Gas furnaces require ignition in order to produce a flame and heat, so without the electrical ignition system working properly, your furnace will be unable to heat your home–full stop.
Thermostat Malfunctions
If your thermostat is acting up, it could be due to an electrical malfunction. The thermostat is vital for complete control over your heating system, and even a minor malfunction could lead to uncomfortable temperatures or wild inefficiencies that can run up your heating bill.
Thermostats are one of the most important components of your heating system, and it’s also universally run with electricity. Just because your furnace operates with gas does not mean your thermostat does too. Even older digital thermostats still require a stable electrical connection with your home’s power grid to operate successfully.
So, if you’re having trouble controlling your heating system, make sure you get your thermostat fixed or replaced.
