Identifying a Blown Fuse in Anthem, AZ

If you’re at a loss about how to tell if your AC fuse is blown, then you won’t appreciate that many blown fuse indicators could mean something else. When in doubt, let HVAC technicians figure it out.

Air Conditioner Won't Start

If your air conditioner won’t turn on at all, it could be a sign that the fuse is blown. The blown fuse will stop power from reaching the unit at all. If you noticed your air conditioner having electrical problems leading up to this point, it’s very likely the fuse, but an electrical fuse inspection will make it clear.

Smoke or Smells Like Burning

Fuses have a smoky smell when they blow out but it quickly dissipates. If the smell doesn’t go away or you see smoke coming from the fuse box, you may have an electrical fire brewing. Contact emergency services to get the fire under control, then contact professional HVAC technicians to replace the blown fuse.

Warm Air

If warm air blows from your vents despite being on the cool settings, this could be a fuse issue. Some air conditioners have separate fuses on the indoor and outdoor units. When the outdoor fuse blows, it can no longer create cool air, though it will continue to blow air throughout your home.

Frequent Circuit Breaker Tripping

If your air conditioner circuit breaker always trips, it could be that the fuse provides too much power. Circuit breakers trip when excessive power is allowed through the system. This is one of the harder fuse replacement signs to detect since many variables can cause a circuit to trip.

What Causes a Blown Fuse?

Now that you know how to tell if your AC fuse is blown, it helps to know what causes it to happen so you can prevent it from happening again. After an HVAC technician completes AC fuse testing, they can give you a clearer picture of the problem and solution. Until then, general causes include:

  • Overheating: If your air conditioner has to work extra hard to cool down your home due to dirty air filters or other problems, the system may overheat and blow a fuse.
  • Capacitor issues: The capacitor regulates how much energy can flow through the system. If it malfunctions and allows too much in the system, it will likely blow a fuse.
  • Loose electrical components: Loose wires and parts could cause the system to malfunction when they heat up.
  • Too much power: Fuses blow when too much power goes through them. You’ll likely have a tripped circuit board along with a blown fuse.

Should You Call for Repairs?

Fuse continuity checks should be left to the HVAC professionals. It’s possible to test fuse box voltage yourself, but it’s extremely dangerous since you’re handling live electricity. Unless you’re a licensed HVAC technician or electrician in Anthem, AZ, you shouldn’t touch the fuse box on your own. Learn how to tell if your AC fuse is blown so you can know when to call for repairs rather than attempting dangerous DIY projects.

Professionals can inspect the entire system to ensure the blown fuse is the only problem. They may determine that the entire fuse box or breaker box should be replaced for safety purposes or to create a more climate-friendly home. They may also determine that other parts of the air conditioner unit should be repaired or replaced, especially if it recently had electrical issues.
