Your home’s air conditioner is always trying to keep up with the temperature demands of your home. But if your system is dealing with internal issues or the outdoor temperatures are significantly hotter than usual, your air conditioner might end up trying to draw more power than it can actually handle. That’s where AC fuses come in.
In the latest blog post from Sanborn’s Air Conditioning & Heating, we’ll discuss what AC fuses are, how to tell if one is blown, and why your AC fuse might have blown. Contact Sanborn’s today to learn more or to schedule AC services in the Redlands, San Bernardino, or Inland Empire areas.
What is an AC Fuse?
All air conditioning systems have fuses as a way to protect your home from electrical damage and even fires. If an air conditioner attempts to draw too much amperage, the system will redirect the power supply to the fuse to prevent a system overload. This breaks the circuit and prevents damage to your home or air conditioner.
Because fuses are so important in the cooling process, your air conditioner will not be able to run with a blown fuse. If your system’s fuse blows, make sure to have it replaced quickly in order to restore cool temperatures to your home.
How to Tell if Your AC Fuse is Blown
If your air conditioner has a blown fuse, it won’t be able to access power in order to produce cool temperatures. In these instances, you’ll probably notice that your air conditioner is making a humming noise, indicating that the system is still trying to receive an electrical current. The blown fuse will need to be replaced in order for the system to run again.
When you’re dealing with a blown AC fuse, you should always contact a professional to replace the fuse and diagnose the cause. Fuses can be blown due to a number of problems, and if you replace the fuse without addressing the root issue, your new AC fuse will likely blow again soon after replacing it.
What Can Cause an AC Fuse to Blow?
Low Refrigerant Levels
When refrigerant levels are too low, your AC will use more energy in an effort to cool your home. If it tries to use too much amperage at once, it will blow its fuse.
Loose Electrical Components
Over time, electrical connections can loosen, leading to a tripped breaker and blown AC fuse. Electrical connections should be tightened by a professional to ensure that issues do not reoccur in the future.
High Outdoor Temperatures
The hotter the outdoor temperatures, the more energy your AC will need to use in order to meet your temperature demands. Drawing too much energy will blow the fuse.
Dirty air filters can restrict airflow, making it harder for your air conditioner to keep your home cool. The system will attempt to use more energy to cool your home, potentially blowing your AC fuse in the process.
