When summer hits in Cedar Hill, there are certain questions you won’t want to find yourself asking about your air conditioner. First of all, you won’t want to be asking:
“How do I know if my AC fuse is blown in my house?”
Cedar Hill is a friendly Texas town to settle down in, situated just outside Dallas. What isn’t so nice, however, is dealing with extreme heat without an AC. If your air conditioner’s fuse blows when you need it most, then you need to get in touch with the best of Cedar Hill’s AC repair technician talent.
A low-voltage fuse is designed to regulate the electrical currents and circuits in your AC system. This fuse is an integral part of your HVAC system’s control board. If an electrical fault happens, this fuse will “blow” or burn out.
This protocol will protect the other components of your AC from suffering surge damage. However, they’ll still need professional service to get back up and running. Let’s look at the signs and symptoms of a blown fuse, and when they warrant professional service.
Common Signs That Your AC Fuse Has Blown
Visual and physical damage will show the most common signs of a blown fuse. You could see visible breakage in the metal filament, or discoloration on the window by the fuse. Alternatively, you could notice any one of the following three performance issues, all of them indicative of a blown fuse.
1. Your AC Works Harder To Power On
If your low-voltage fuse is blown, you might notice your air conditioner taking longer to power on. Alternatively, it might be failing to power on altogether. In either case, if adjustments to your thermostat fail to make a difference, that could indicate a blown fuse.
2. Your Circuit Breaker Is Tripped by the Blown Fuse Box
A blown low-voltage fuse in your HVAC system could frequently trip your circuit breaker. Notice it tripping every time you turn on your air conditioner? That could be an indicative sign of a blown fuse.
3. Your Air Conditioner Unit Is Failing To Blow Cold Air
Various issues could cause this problem. But what if it’s because of a blown fuse? If so, then your AC will be failing to draw the necessary current it needs to circulate cool air.
Test your thermostat settings. Is your AC failing to respond to the commands you input? Is your air conditioner failing to adjust to different cooling or energy efficiency settings? That could be a tell-tale sign of a faulty low-voltage fuse.
Common Causes of Blown Fuses in Your Air Conditioner
So, you suspect that your AC’s fuse is blown in your house. Now what? How do you determine the culprit of your blown fuse?
Multiple issues could be to blame for your blown fuse. These could include:
- A circuit that’s short or overloaded: Line wire insulation can deteriorate, causing a short circuit; too many connected devices can overload a circuit.
- Electrical power surge in the fuse: Overvoltage bursts can blow fuses, usually from power outages, lightning, or malfunctioning appliances.
- Malfunctioning thermostat or control board: The voltage balance in these two appliances can malfunction, overwhelming your fuse box.
- Incorrect or improper fuse: Your fuse needs to match the amperage of your AC unit; if it’s too high or too low, it could blow.
- A failing HVAC transformer: If your transformer fails, it could send high voltages to your HVAC system’s low-voltage circuits.
- Dirty filters or condenser coils: Neglecting to maintain these components could cause them to clog up with contaminants.
Regardless of the cause, a blown fuse will need prompt service. One small, faulty fuse is all it takes to disable your entire HVAC system. Professional expertise will provide your best bet at getting it back up and running.
