Why Is My Heat Pump Tripping The Circuit Breaker?

Mini split heat pumps are the most state of the art solution for heating and cooling, but they can still have problems from time to time. When a heat pump keeps tripping breaker switches, it’s important to get to the bottom of the issue as quickly as possible. For one thing, a home without a functioning heat pump can become uncomfortable in a hurry, so it’s good to restore service as soon as possible. Further, the problem may be serious enough to cause expensive damage or even safety risks.



One of the most common issues ductless heat pump owners experience is a system that won’t turn on or stay on. In some cases, this problem can be resolved easily without placing a service call. Homeowners can proceed through a series of troubleshooting techniques to diagnose the issue and determine if they need professional heat pump repair. Common causes of heat pump problems include the following:

  • Heat pump units locking up to prevent use
  • Electrical panels with blown fuses
  • Engaged emergency shutoff switches
  • A tripped reset button on the outdoor unit
  • Incorrect settings on the thermostat
  • Circuit breakers in the off position, or tripped breakers

Of all of those possibilities, tripped circuit breakers are among the most common issues homeowners experience with their heat pumps. Try closing the breaker to cut electricity to the heat pump, then turning it back on after a full minute. If that isn’t enough to get your heat pump back up and running, try to get to the root of the problem instead of turning the breaker on and off again every time you need air conditioning.

In some cases, the solution can be as easy as making sure the thermostat is in the right position. If the thermostat is properly configured but your system still won’t start, you might be able to restore function by pressing the reset button on your outdoor unit. Also, look to see if any emergency switches are engaged because that may point to a more severe problem.
