A fuse in a control pack of a hot tub is a safety device that is designed to protect the electrical components of the hot tub from damage due to an overcurrent




  • An overcurrent occurs when too much electrical current flows through a circuit, and it can happen for a variety of reasons, such as a short circuit or a malfunctioning component. When the overcurrent occurs, the fuse will "blow," or break the circuit, to prevent further damage to the hot tub's electrical system.


The control pack has multiple circuits, each have their own designated fuse, in order to protect them from overcurrent.





  • A fuse is typically a small metal or ceramic device that contains a piece of wire or filament that melts when too much current flows through it. Once the fuse "blows," the hot tub's electrical system will shut down and will not work until the fuse is replaced with a new one.


It's important to check the fuses regularly, if one is not functioning, you may need to replace it. And also make sure to check the user manual or consult our team or a professional technician to know the correct type of fuse and the amperage of the fuse required for the hot tub control pack.
