Can a burnt out circuit board be a problem?
A burnt-out circuit board can be a costly repair, and is the ultimate consequence of poor hot tub maintenance. Routine maintenance is the best way to avoid expensive issues such as circuit board malfunction.
Why does my hot tub keep Tripping the circuit board?
If the GFCI holds, then you have found the cause of the GFCI tripping. It will need to be replaced. If you have everything unplugged (including the main pump) and it still trips, then there may be an issue with the transformer that is soldered or plugged into the circuit board. If the transformer plugs into the board it can be easily replaced.
What to do if hot tub pressure switch is miscalibrated?
If you don’t confirm water is moving in the hot tub and through the heater do not proceed with the next step as in doing so may burn out the heating element. To check to see if the pressure switch is defective or miscalibrated, please do the following: Power down the circuit board.
What should the voltage be on a hot tub circuit board?
If you DO have 220 volts across both hot wires coming from the house, then next measure the voltage across both heating element pins. You should see 220 volts. If you do not, then the circuit board is faulty and will need to be replaced or sent to us for repair.

When to send a circuit board to repair?
Give it a quick diagnosis. Sure signs of damage include burn marks, cracks and melted components. Once you determine the circuit board has malfunctioned, consider sending it to a repair service.
