AC Tripping Circuit Breaker? Troubleshoot and Keep Your Cool!

Title: Troubleshooting AC Tripping Circuit Breaker: A Comprehensive GuidePicture this: it’s a sweltering summer day, and you’re relying on your trusty air conditioner to keep you cool and comfortable. Suddenly, your AC unit abruptly shuts off, and you notice that the circuit breaker has tripped.

Frustrating, isn’t it? Don’t panic.

In this article, we will explore the various causes of AC tripping circuit breakers, both non-electrical and electrical, and provide practical solutions to help you troubleshoot the issue. So, let’s dive into the world of AC troubleshooting and get your cool breeze back!

1) Non-Electrical Causes of the AC Tripping Circuit Breaker:

1.1 AC Unit has a Cover:

If your AC unit has a protective cover, it may overheat, causing the circuit breaker to trip.

Ensure that the cover is removed, especially during the summer months, to allow adequate airflow around the unit. 1.2 Dirty Furnace Filter:

A clogged or dirty furnace filter obstructs airflow, leading to reduced efficiency and overheating of the AC system.

Regularly inspect and replace or clean the air filter to keep the system running smoothly. 1.3 Dirty Condenser Coil:

Outdoor debris, such as leaves and dirt, can accumulate on the condenser coil, reducing its efficiency and obstructing proper heat transfer.

Clean the condenser coil regularly to prevent AC overheating and circuit breaker trips. 1.4 Refrigerant Issues:

Refrigerant leaks or an overcharged system can result in an imbalanced cooling process, causing the AC compressor to strain and potentially trip the circuit breaker.

Consult a professional HVAC technician to diagnose and resolve refrigerant-related problems. 2) Electrical Problems:

2.1 Burned Out Condenser Fan Motor:

A burned-out condenser fan motor prevents proper heat dissipation, leading to AC overheating and circuit breaker trips.

Replace the faulty motor and ensure the fan blade is undamaged for optimal cooling efficiency. 2.2 Bad Wiring/Wire Shorted to Ground:

Improper or damaged wiring can cause a short circuit, leading to the AC unit drawing excessive current and tripping the circuit breaker.

Engage a qualified electrician to inspect and replace any faulty wiring. 2.3 Excessive Power Draw from Compressor:

Sometimes, an AC compressor requires additional power during startup, resulting in an excessive power draw that trips the circuit breaker.

Consider installing a hard start kit to manage the power fluctuations and prevent tripping. 2.4 Shorted Out Compressor:

A shorted out compressor can cause an electrical overload, causing the circuit breaker to trip repeatedly.

In this scenario, replacing the compressor is the most effective solution. Seek professional assistance for compressor replacements.

2.5 Defective Contactor:

A defective contactor, responsible for connecting the AC unit to power, can cause frequent circuit breaker trips. Look out for buzzing noises or signs of wear and tear and replace the faulty contactor if needed.

2.6 Weak Circuit Breaker:

Old or weak circuit breakers may fail to handle the electrical load demanded by the AC unit, leading to tripping. Installing a new, appropriately rated circuit breaker can alleviate this issue and ensure a smoother function.

Remember, if you’re uncomfortable or unfamiliar with electrical work, it’s always best to consult a professional HVAC technician or electrician to ensure the safety and efficiency of your AC system. Conclusion:

Though AC tripping circuit breakers can be aggravating, armed with knowledge about the various causes and solutions, you can now tackle these issues with confidence.

Regular maintenance, diligent cleaning, and proactive measures like installing hard start kits can help you avoid frequently tripping circuit breakers. By troubleshooting both non-electrical and electrical problems, you can keep your AC unit running smoothly, providing the cool comfort you deserve, even on the hottest of days.

Stay cool, my friends!
