There’s nothing more disappointing than heading out to your hot tub for a nice hot soak in the warm, bubbly water only to find that your jets just aren’t working. You turn on your hot tub and nothing happens and you begin to wonder what the heck is going on. In most cases, it’s simply a problem with the spa blower.
Now while that might sound like a major repair, they are actually fairly simple devices and are connected in virtually the same way on all major hot tubs. While you can always call a plumber or hot tub repair technician to your home to do it for you, you can often perform these repairs fairly easily yourself, saving a bucket of money in the process.
What Is a Spa Blower?
Before you embark on a this hot tub repair, it’s helpful to know at least a little bit about how the blower works. It’s a pretty simple unit, consisting of a fan motor and a housing.
Rather than repair a spa air blower, it’s recommended that you actually just replace the entire assembly instead of trying to fix the motor as you won’t see a major cost savings by doing so, and the repair can often be much more complicated than simply replacing it.
A hot tub blower can be either 110V or 220V, depending on the type of hot tub you have. When purchasing a replacement part, make sure you buy the one that matches your hot tub and its electrical requirements.
Spa blowers are usually plumbed in one of two ways. In one type, the air from the blower runs to a manifold and is then distributed to smaller air lines that run to the injector jet fittings. In the other, a channel cavity is adhered to the shell of your hot tub, which has holes drilled in it to allow the air to pass to the water.
This blower features a rubber motor mount that suppresses noise and allows the motor to operate without interference, enhancing durability and performance.
A Word of Warning about Spa Air Blowers
Peanut butter and chocolate. The Captain and Tennille. Rama lama lama ka dinga da dinga dong. Lots of things go together. But two things that absolutely do not go together are water and electricity.
Hot tub air blower repair or replacement means you’ll be working with both of them. If you’re not confident you can do that safely, please call a professional technician.
If you do believe you can do it, you must take a few safety precautions first.
Make sure you cut all electricity to the hot tub before you even begin to remove the covers. Turn off the circuit breakers, unplug any plugs from their outlets, and then double check to make sure there is absolutely no power running to your hot tub before you begin.
