Why is my Tiger River Sumatran Hot Tub not heating but jets and light are working?

If your Tiger River Hot Tub is not heating, but the jets and light are working, it could be due to: * **Integrated Pressure Switch:** Check for clogged filters. The integrated pressure switch will reset once water flow through the heater is restored. If the heater frequently trips, call for service. * **Circulation Pump Thermal Cut-Off:** Inspect for clogged filters or air locks in the plumbing. To reset, disconnect power to the spa and allow the circulation pump to cool down. The thermal cut-off will reset when the pump has cooled and power is reapplied. If it continues to trip, call for service.
