Four Symptoms of a Bad Capacitor on a Gas Surface

The gas furnace in your Melbourne, FL home might just have the easiest job. Considering the Florida heat and humidity, you probably don’t use your furnace that much. Unfortunately, this makes it harder to spot the issues that often pop up.
For example, how can you tell you’ve got a bad capacitor? What are some of the bad furnace capacitor symptoms, and what should you do to fix them?
In this post, we’ll take a closer look at the role the capacitor plays in your gas furnace, guiding you on how to tell when professional heating repair in Melbourne, FL, is necessary.
How the Gas Furnace in Your Melbourne Home Works
Few homeowners are interested in learning how the appliances in their home work. Take the gas furnace, for instance. For most homeowners, their focus is on enjoying warm air whenever they turn on the furnace. However, how is all of this made possible?
Basically, when you switch on your furnace, the pilot ignites the gas and allows the burners to warm the air. The fan then distributes the warm air throughout your Melbourne home.
That fan contains a motor, which has a capacitor inside. Since your gas furnace can use up quite a bit of energy, the capacitor’s function is to regulate the amount of electricity the motor receives.
In short, the capacitor acts like your furnace’s battery. It stores the extra energy required to jump-start the furnace’s motor and blower. If it develops even the slightest issue, your gas furnace won’t be able to heat your home sufficiently.
How To Tell You Have a Bad Capacitor
With all the moving parts your furnace has, it can be hard to pinpoint the issue. Fortunately, there are a few bad furnace capacitor symptoms that’ll help guide you.
1. Furnace Humming Noises
Anytime your capacitor isn’t working as it should, your furnace may start making a strange, low-humming noise the moment you turn it on. In extreme cases, the noise could continue indefinitely.
2. Intermitted Furnace Cycling
Does your gas furnace go off shortly after you’ve switched it on, only to come on once again in quick succession? It probably has a faulty capacitor.
Sometimes, when you operate a furnace with a bad capacitor, it will quickly overheat. When this happens, your unit’s limit switch will turn it off to prevent potential damage.
3. Weak Blower Motor
Since the capacitor powers the blower motor, one way to determine if it has a problem is to observe how the motor is running. The motor might be weak, causing it to run slower. As a result, you’ll start experiencing fluctuating fan speed or a delayed fan start.
4. Burning Smell
A burning smell coming from any appliance is never a good sign. If that appliance happens to be your gas furnace, chances are your capacitor has developed an electrical issue. The wires that power it could either be corroded or frayed.
Fixing a Bad Capacitor
Knowing what the bad furnace capacitor symptoms are is only the first step. What you need to figure out next is what to do about them.
Turn off Your Furnace
Start by switching off your gas furnace the moment you notice any of the symptoms we’ve shared above. It is especially crucial to do this before attempting to conduct a visual inspection of your capacitor. In fact, for extra safety, you should turn off the circuit breaker as well.
Conduct a Visual Inspection
Sometimes, the issues you’re experiencing could be the result of something other than a bad capacitor. One way to know for sure is to conduct a visual inspection. Check for signs of damage, such as a leak, bulging top or bottom, or a burnt or cracked casing.
