It's a good heater. If it's broken, you can get it.
We, along with many other tub dealer sell parts for other spas. If you need help finding one let us know. It may be something proprietary, so you should check with your local friendly jacuzzi dealer first. Best to give them the opportunity to help you. You may need them when it's 10 degrees outside.
