AC Breaker Keeps Tripping? Here’s What to Do
Have you noticed that your AC behaves strangely and the AC breaker keeps tripping? It’s a sign that something is not good with your system. Maybe your AC system is overloaded, or there is an electrical fault. Whatever the problem is, you should not ignore it. You must quickly address it and prevent further damage. Actually, it’s about your home safety. In this article, we will discuss common reasons for a tripping breaker and guide you on what steps to take before contacting a professional. Understanding the cause can help you quickly tackle the problem and avoid unnecessary headaches.
What is the role of an AC breaker?
An AC breaker is a crucial safety device in your home’s electrical system. Its job is to protect your home from electrical problems. A breaker prevents electrical overload by automatically shutting off the power when the current exceeds safe levels. This protects your air conditioner and electrical circuits from overheating, short circuits, or even fire hazards. Without a functioning breaker, your AC system could suffer significant damage, and safety risks in your home would increase. So, it’s alarming if it shuts off repeatedly.
Why does my air conditioner keep tripping the breaker?
There are several reasons for this malfunction.
Dirty air filters
Air filters keep dirt and dust out of your AC system. But when they are clogged, airflow is restricted. This seriously overloads the system. It overheats and draws more power, which trips the breaker. Clean or replace your filters regularly, especially during summer, and it will keep your system running smoothly without unnecessary strain.
Refrigerant leaks
Refrigerant is what cools the air, and if there’s a leak, the levels drop, and your AC struggles to keep up. The compressor has to work overtime. Again, it draws too much electricity and the breaker trips. Signs of a leak are poor cooling, ice on the coils, or a hissing sound. You must immediately repair the leak and refill the refrigerant to avoid further damage.
Short circuits
A short circuit happens when wires touch where they shouldn’t, causing a surge of electricity. This is dangerous and can trip the breaker instantly. You may notice a burning smell or see scorch marks near the AC unit. If you suspect this, turn off the system and call a professional to fix it right away.
Faulty wiring
Old or damaged wiring can cause inconsistent electrical flow and lead to frequent breaker trips. If the wires aren’t up to the power demands of your AC, they can overheat and AC trips breaker after 5 minutes. A licensed electrician can check and fix any wiring issues to keep your system safe and reliable.
Faulty AC fan
The fan inside your AC moves air over the evaporator coil and helps expel heat. If the fan motor is faulty or the blades are damaged, it can overheat the system and trip the breaker. You might hear odd noises or notice less airflow if the fan isn’t working properly. Fix it quickly to prevent bigger problems.
Compressor issues
The compressor is the heart of your AC system, and it uses the most power. If it is worn, damaged, or overheated, it starts using too much electricity and trips the breaker. Signs of trouble include loud noises, trouble starting, or warm air from your vents. Don’t miss minor issues and avoid the cost of a full replacement.
Frozen evaporator coil
The evaporator coil absorbs heat, but when it freezes, it disrupts the whole cooling process. This can happen if the airflow is restricted by dirty filters or if there’s a refrigerant problem. A frozen coil forces the system to overwork, and the AC trips breaker after few hours of work. Let the ice melt, then identify and fix the cause to avoid repeat issues.
Troubleshooting tips for AC tripping
When you face this problem, follow these steps to troubleshoot the issue and protect your system:
- Turn off the AC and reset the breaker. The first step is to switch off the air conditioner at the thermostat and then go to your electrical panel. Flip the breaker completely off and then back on to safely reset it.
- Inspect the air filter. It may be simply a problem with restricted airflow. Check the filter and replace it if it looks dusty or discolored.
- Look for ice or blockages. Check the AC unit for frozen evaporator coils or any visible obstructions. If you see ice, turn off the system and let it defrost. Clear away any debris that is blocking airflow.
- Clean the outdoor condenser. Dirt, leaves, and debris can collect around the outdoor unit and reduce efficiency. Use a garden hose or clean by hand to remove buildup and improve airflow.
- Check the thermostat settings. Ensure your thermostat is set to a reasonable cooling temperature and functioning properly. Incorrect settings can strain your system.
If the breaker keeps tripping after these steps, it’s better to call a professional HVAC technician who will investigate the problem further.
When to invite a professional?
Sometimes, an AC breaker that keeps tripping cannot be quickly fixed. It can be a signal of a bigger issue. When do you need professional help?
- If the AC trips breaker immediately after you reset it, it’s time to bring in an expert. It can be an electrical problem, for example, a short circuit or an overloaded system, and it needs professional attention.
- If you notice damaged wires or burnt spots around the unit, don’t try to handle it yourself. Exposed or damaged wiring is dangerous and can even cause a fire.
- Unusual noises like buzzing or humming or odd burning smell are also alarming sighs. These may indicate a motor issue, refrigerant leak, or overheating part that must be examined.
