I would like to express how excellent this company is. I inherited a house with a 2007 Hotspring Aria hot tub. The spa hasn’t been operated in years and when I turned it on, it ran for about 10 minutes and died. I mean dead died. I knew absolutely nothing about hot tubs but with the excellent diagnosis videos, installation videos and superior phone support, I was able to replace the main control board, heater relay board, heater, circulation pump, the ozonator and all associated tubing. This took 4 1/2 hours over two days (I had to watch videos) but the spa runs like new! I had one question regarding the jumper voltage 18 or 12. I spoke with a technician and he was able to answer my question as well as helping me double check the voltages for the components on the relay board. I am handy with electronics and electricity and am comfortable working with 230 volts. Shipping was fast and as expected. I highly recommend BackYardPlus.On 06/28/2024 by F. R. (verified customer)
These control boxes and their circuit boards do on occasion just grow tired as any outdoor computer could. No worries, we have just the right complete factory replacements as well as the internal parts all from the makers of Hot Spring, Tiger River, Solana, Limelight, and Hot Spot Spas.
