To tell if a hot tub circuit board is bad, look for signs like burn marks, visible damage, or a burnt smell on the board. Also, if your hot tub displays error codes, won’t turn on, or certain functions don’t work even after checking fuses and connections, the circuit board may be faulty. Testing with a multimeter can help confirm if components on the board are not receiving or sending power as they should.
