An air compressor running slow and tripping the breaker is often caused by an aging compressor that has trouble starting and pulls more electricity, causing the breaker to trip. A solution is to have an AC technician install a “hard start kit,” which is a capacitor that gives the compressor motor an extra electrical jolt to get it moving.
Circuit breakers can also trip due to current surges when a motor starts, shorts, ground faults, rusty connections, or extension cords. Additionally, low refrigerant charge can cause the compressor to overheat and trip the thermal overload protection device. Another potential issue is a weak or defective capacitor, which can trigger a tripped breaker if the compressor doesn’t receive adequate starting power.

Common Causes Of Slow Running And Tripping Breaker
When your air compressor is running slow and tripping the breaker, there are a few common causes that you should consider. By understanding these causes, you can diagnose the issue and take appropriate action, ensuring your air compressor runs smoothly and efficiently. The following are some of the most common causes of slow running and tripping breaker.
Excessive Current Draw
One potential cause for a slow running air compressor that trips the breaker is excessive current draw. If the compressor motor draws more current than the breaker’s capacity, it can overload the circuit and cause the breaker to trip. This can happen when the compressor ages and has trouble starting, pulling even more electricity. To resolve this issue, you can have an AC technician install a “hard start kit.” This kit includes a capacitor that provides the compressor motor with an extra electric jolt to get it moving.
Low Refrigerant Charge
Another possibility for slow running and tripping breaker is a low refrigerant charge. If the refrigerant charge is too low, it can cause the compressor to overheat and trip the thermal overload protection device. This can result in the air compressor running slowly or not running at all. To rectify this issue, you should check the refrigerant levels and ensure they are at the appropriate level. If the charge is low, you may need to add refrigerant to the system. It is important to consult with an HVAC professional to properly diagnose and address the issue.
Understanding The Relationship Between Current Draw And Breaker Tripping
How A Circuit Breaker Works
A circuit breaker is an important safety device that protects electrical circuits from overloading and causing damage. It acts as a safeguard by automatically shutting off the power supply when the current exceeds its rated capacity. When the circuit breaker trips, it interrupts the flow of electricity, preventing any potential hazards like electrical fires or damage to electrical equipment.
Motor Starting Current Surge
One of the common reasons behind an air compressor running slow and tripping the breaker is the excessive current draw during motor starting. When the compressor motor starts, it requires a high amount of electrical current to get it moving. This abrupt surge of current can exceed the capacity of the circuit breaker, causing it to trip. It is important to note that this starting current surge is temporary and should stabilize once the motor is up to speed.
Overload Protection Device
Another factor that can cause an air compressor to trip the breaker is an overload on the motor. If the compressor motor draws excessive current due to various reasons such as worn-out components or low refrigerant charge, it can trigger the overload protection device. This device is designed to detect when the current exceeds a safe limit and automatically turns off the compressor to prevent any damage or overheating.
If you are experiencing an air compressor that runs slow and trips the breaker, it is crucial to identify the root cause of the issue. It could be a faulty capacitor, low refrigerant charge, or an overloaded motor. Consulting with an HVAC technician is recommended to diagnose and resolve the problem effectively. They can assess the compressor’s condition, install a hard start kit if necessary to provide an extra electrical boost during startup, or replace any defective components as needed.
Solutions For Slow Running And Tripping Breaker
Installing A Hard Start Kit
If your air compressor is running slowly and tripping the breaker, one possible solution is to install a hard start kit. This kit includes a capacitor that provides an extra electrical “jolt” to the compressor motor, helping it start more efficiently. By giving the compressor motor the extra boost it needs, the hard start kit can prevent slow running and reduce the chances of the breaker tripping. To install the hard start kit, it is recommended to seek the assistance of an AC technician who can ensure proper installation and compatibility with your specific compressor model.
Checking And Replacing Run Capacitor
Another potential solution for a slow running air compressor that trips the breaker is to check and replace the run capacitor. The capacitor is responsible for providing the necessary electrical energy to start the compressor motor and keep it running smoothly. Over time, capacitors can weaken or fail, leading to slow running and breaker tripping. To determine if the run capacitor is the issue, visually inspect it for any signs of damage or bulging. If there are visible signs of damage or if the capacitor fails a capacitance test, it is recommended to replace it. Again, it is advisable to consult an AC technician for proper diagnosis and replacement of the run capacitor.
Addressing Low Refrigerant Charge
Low refrigerant charge can also contribute to a slow running air compressor that trips the breaker. When the refrigerant charge is too low, it causes the compressor to work harder and overheat, resulting in slow performance and breaker trips. To address this issue, it is crucial to have a professional HVAC technician assess and recharge the refrigerant to the correct levels. They will also inspect the system for any leaks that may be causing the refrigerant to escape, leading to the low charge. By addressing the low refrigerant charge, the compressor can operate at optimal levels, reducing the risk of slow running and breaker tripping.
In conclusion, if your air compressor is running slow and tripping the breaker, it is essential to explore these potential solutions. Installing a hard start kit, checking and replacing the run capacitor, and addressing low refrigerant charge can all help resolve these issues and ensure your air compressor operates efficiently and safely. Remember to consult with a qualified AC technician for proper diagnosis and implementation of these solutions.
