Air conditioner is a “life-saving appliance” in summer and winter, but frequent tripping not only ruins the user experience but also can lead to safety hazards to circuits.
In this article, the most common reasons behind air conditioner circuit breaker tripping will be discussed and some practical tips provided to assist you in troubleshooting at the earliest and ensuring electrical safety.
Air conditioning circuit overload
Air conditioning belongs to high-power appliances (especially when starting cooling/heating).
If high power consuming devices such as refrigerators and microwave ovens are connected to the same circuit at the same time,
and the total current exceeds the rated value of the circuit breaker (such as 16A, 25A), overload protection tripping will be triggered.
Solution: Use a separate circuit for the air conditioner to avoid sharing it with other high-power appliances.
Air conditioning leakage fault
Leakage in air conditioner or in circuit will lead to tripping of leakage protection circuit breaker (model with “reset button”).
Common errors are: water into the wiring board of the air conditioner’s outdoor unit, short circuit or aging of the circuit
The impact of unstable voltage on air conditioning
Excessive voltage fluctuation is another common reason for tripping of air conditioning circuit breakers.
Unstable power grid or high or low voltage causing abnormal air conditioning operation initiates circuit breaker protection.
A voltage regulator can be installed. A voltage regulator can provide a stable voltage and avoid air conditioning damage from voltage fluctuation
Internal malfunction of air conditioner
Electrical component faults in the air conditioner, such as compressors, motherboards, fan motors, etc., also trip circuit breakers.
When there is a short circuit or overload in the air conditioner, the circuit breaker automatically switches off the power to prevent accidents.

Air conditioning aging and equipment lifespan
As air conditioning is used over long periods, its internal systems gradually degrade, especially the core elements such as electrical components, compressors, and motors. Gradual aging of these components not only weakens the overall operation of the air conditioner, but may also lead to more frequent malfunctions.
Particularly when the air conditioner circuit becomes worn out gradually, there will be unstable current fluctuations, which can quickly cause repeated tripping of the circuit breaker. Unstable current over the long term can speed up the degradation of other essential components, even influence the cooling performance of the air conditioner, raise energy consumption, and reduce the service life of the equipment. Therefore, regular maintenance and regular inspection of the internal electrical system of the air conditioner are necessary to extend the life of the equipment.
summarize
The reasons for frequent tripping of air conditioning circuit breakers may be multifaceted, ranging from circuit overload, voltage fluctuations to air conditioning faults, all of which can trigger tripping.
By regularly checking the status of air conditioning, circuits, and circuit breakers, timely resolution of equipment aging and circuit issues can effectively reduce the occurrence of circuit breaker tripping.
