Common causes
A mini-split can trip the circuit breaker when there is an electrical fault or when a component draws more current than expected. Possible causes include a short circuit or ground fault, damaged or loose electrical connections, a defective capacitor in systems that use one, compressor problems, failing motors or a breaker that does not match the system requirements. If the breaker trips immediately when the mini-split starts, it may indicate a significant electrical fault. If it trips after several minutes of operation, diagnosis may require checking system current draw and components.
When to request service
If the circuit breaker trips repeatedly, turn the mini-split off and do not keep resetting the breaker. If there is a burning smell, smoke, sparks, damaged wiring or unusual electrical noise, keep the system off and request professional service. Do not replace the breaker with a higher-amperage breaker or open electrical panels to diagnose the problem yourself.

Frequently asked questions
Why does my mini-split keep tripping the circuit breaker?
Possible causes include an electrical fault, short circuit or ground fault, damaged or loose connections, a defective capacitor in some systems, compressor or motor problems, or a breaker that does not match the system requirements.
What does it mean if the breaker trips immediately when I turn on the mini-split?
If the circuit breaker trips immediately, there may be a significant electrical fault. Keep the system off and request professional diagnosis.
What if the breaker trips after the mini-split has been running for a few minutes?
A breaker that trips after several minutes may be related to electrical current draw or a component that develops a fault while the system is operating. Professional diagnosis is needed to identify the cause.
Should I keep resetting the breaker if the mini-split trips it?
No. If the circuit breaker trips repeatedly, turn the mini-split off and do not keep resetting it. If there is a burning smell, smoke, sparks or damaged wiring, keep the system off and request professional service.
