Checking The Thermostat And Heater Contactor
You need to find the Heater Contactor in the control box (see picture).
If the heater contactor it is not arced/welded shut and moves up and down freely, then the thermostat needs to be replaced. Thermostats are located in one of two places on a spa, either on the top of the spa (spa sides), or in a control box where the equipment is.
See Thermostats in Spa Parts section. Replace the contactor if it was arced/welded shut.
See contactors in Spa Parts section.
In some cases, both of these will need to be replaced.
NOTE: Contactors arc or weld themselves shut due to "chattering" caused by:
- Low water level in spa
- Pressure switch out of adjustment
- Clogged or old filter
- Solid state thermostats
ONE MORE NOTE: Leaving your jets (jet pump) on for a long period of time will also cause the water to over heat.
