My hot tub is a blue ridge spa it has a gatsby circuit board and I can not get the thing to stop overheating no matter what I set the temp to it just goes up to the highest point and then it shuts itself down. Have new senors and new heater..

Does this have a burnt spot on it

I'm not familiar with that spa but I would guess a stuck relay on the circuit board or a bad temp sensor (thermostat).

how do u fix a stuck relay

You could try to tap on it with the back of a screwdriver - I'm not sure which one it is. Some people will solder a new relay on the board or replace the board, which can be expensive.

Remember I am just guessing on the stuck relay!!!
