Relays and contactors control the functions on a hot tub or pool system. They are usually located on the conrol board. They can fail over time. Often when something on your spa doesn’t work it is because the relay or contactor did not work. If you are handy and know how to test for bad relays and contactors, you can replace these and save yourself from buying a complete new board.
Sensors tell your pool or spa if what it is being asked to do is being done. For example the temperature sensor on your spa tells the heater to turn off or on based on the temperature you have programed and the temperature that it is sensing. If it is lower than what you have asked for it tells the heater to turn on. If it is the same as what you want it tells it to turn off.
Sensors fail and are usually very easy to replace. Go to AllPartsPoolandSpa.com, look under sensors, go to the manufacturer of your spa pack, pick out your sensor, order it and when it arrives replace your old one with the new one. Now you are good to go.
