Why Does My AC Keep Blowing Fuses & Tripping Circuits?

Why Does My AC Keep Blowing Fuses & Tripping Circuits?

When it comes to problems with your air conditioning unit, you shouldn’t ignore electrical issues. If you have an AC system that continues to blow fuses or trip circuits, the inability to receive proper cooling isn’t your biggest concern. Electrical issues can be very dangerous and should be addressed with the help of a licensed, experienced HVAC technician. When systems are prone to overloading and short-circuiting, homeowners run the risk of long-lasting damage to home appliances and the potential of an electrical fire. When you have an HVAC electrical problem, call on the experts at Frymire Home Services to quickly get to the root of the problem and perform the correct repair.

What Causes an AC to Blow a Fuse or Trip a Circuit?

Identifying why your AC is blowing a fuse or tripping a circuit should be done by a professional as there are various reasons why this could be happening. Most often, this HVAC electrical issue is caused by:

  • Low refrigerant. Low levels of refrigerant require your AC system to use more energy to cool your home. This increase in energy requirements can trip your system. 
  • Loose electrical connections. Temperature changes can cause wires to expand and then contract. These changes can loosen connections in your breaker box, leading to tripped circuits and blown fuses.
  • Fuse box, circuit, or central power issues. Electrical overloads from problems with your fuse box, circuit, or central power supply can trigger a fuse to blow or trip a circuit. You may be tempted to swap the fuse for a larger one, but this is NOT what you want to do. Reach out to a licensed HVAC technician to diagnose the electrical issue and correct it safely and appropriately.
  • Cooling system capacitor problems. Your AC’s capacitor works with the system’s condenser to manage the proper input and output of electrical currents. If the capacitor is faulty, it can lead to blown AC fuses.
  • High temperatures and dirty filters/condenser coils. Higher temperatures mean your system will have to work harder and longer to sustain your home’s target temperatures. If your system’s filter isn’t free of clogs and debris, the extra pressure required for the system to circulate air can blow a fuse or trip a circuit.

You can avoid most AC issues by staying on top of your annual AC maintenance. Get your AC tuned and ready for the heat of a Dallas summer by acting promptly when you see something amiss!
