Hot Springs Heater Relay Board 77119 (Formerly 74618) IQ 2020 Watkins

Worked perfectly!! Easy hook up and the hot tub got nice and hot! Wasn't sure if it was going to work or not since they changed it from the original, but it looks like it will be even better!

Great product, fitted it in no time and working very well. The price was very good considering the same part here in New Zealand is $995nzd!Shipping was great, well packaged and no damage whatsoever.

The heat went out in my Caldera matinique 2003. This is exactly what I needed as the old one had fried in the back upon inspection. It works great now. Easy fix.

I have a 2003 Hot Springs Sovereign spa. Never have had a single problem with it, just took care of it and maintained it as recommended by the manufacturer. Then I noticed the water was getting colder. The ozone bubbled properly, all jets and lights worked properly, etc. I initially suspected the heater may have gone out but when I open the inspection panel to take a peek I noticed the unmistakable smell of a circuit board that had fried. I looked closer and found that the issue was the heater relay board as evidenced by visible burn marks. I located this item and decided to give it a go. After about 20 minutes I had the old board out, the new board in and fired back up the spa. After a few hours the spa was back up to my desired temperature. This is a do-it-yourself project for a moderately capable person and requires few tools . You can save yourself a ton of money doing this yourself. Fast delivery, competitive price, exact fit, easy to understand instructions. Very pleased.

It came on time, instructions were spot on.Hot tub works!

Perfect replacement

after no luck with air bubble fixes i looked much closer at the heater board and could barely see a little black on the front... ordered this, got it fairly quickly, pulled the old board and sure enough cooked on the backside. had to modify the aluminum arm thingy (cut a long notch out with a angle grinder cut off wheel). wired everything up and boom - heat, hot springs spa was back up to temp that evening. i had to cut the spade type connectors off the heater wires and strip the ends to plug into the updated board, better connection system though. so all around got a hopefully better built board and heat restored for less money than i was expecting it to cost to repair. instructions are very good as well.

At first I couldn't get heat to work so I called the seller. I sent him a couple pics and within min he helped me troubleshoot the 2 jumpers not being pushed in far enough. Great customer service. Perfect product.Another local spa dealer said I would have to replace all the components at a cost of nearly $1k. This control board worked great. Thank you!
