Johnr9q Posted March 9, 2019 Report Share Posted March 9, 2019 On the circuit board at the top left, where the fuze mounts, underneath the right prong that holds the fuze, it is burnt and crispy. I can see a bit evidence of smoke on the cover also. The fuze is also blown and burnt on one end. Can you give me suggestions on how to troubleshoot what caused this?

Johnr9q Posted March 13, 2019 Author Report Share Posted March 13, 2019 I don't know if you can see the pictures of the circuit board and the burnt area here but I'll try. The files were too big to post here and I don't know how to reduce them. https://mail.yahoo.com/d/compose/3004454981 Quote Link to comment Share on other sites More sharing options...
Johnr9q Posted March 14, 2019 Author Report Share Posted March 14, 2019 I tried the process of elimination by unhooking the motor, the controller, the heater and any other wire I could unplug from the circuit board. I then put power to the circuit board and, again, got smoke, sparks and another blown fuse Quote Link to comment Share on other sites More sharing options...
Dnepr Dave Posted March 17, 2019 Report Share Posted March 17, 2019 I am not familiar with Balboa spas, I have a Caldera. But if you have unplugged everything from the control board and it still blows the fuse, I'd say it was a problem with the control board.
