High Limit / Temperature Sensors

The high limit is a safety switch which is normally closed until there is a problem with excessive temperature. Once the temp reaches its set point, it latches open, breaking the circuit. This prevents the heater from meltdown if there is an equipment failure.

If your high limit is tripping within a few minutes of activating the heater CHECK FLOW! Little or no water flow will cause this. If it trips at the end of the heating cycle it's probably because at the end, when the pump turns off, the element is still hot, and the water is hot. The temperature at the element can go up for a few seconds and will sometimes trip the high limit. It's best to replace the high limit if this happens all the time.

These sensing devices are present to protect your hot tub from overheat conditions.
