Several things there:

  • The thermostat may be set too low
  • Inadequate gas supply
  • Malfunctioning thermostat
  • You are losing heat faster then you are adding it. (If the heat loss in the pool is greater than the heat input, the heater might be too small or you may need a thermal barrier). Use a thermal barrier to help prevent heat loss
Keep that the heater should resume heating automatically if the timer turned off the system.

Its possible that you need the User Guide like reference:
- Link 1
- Link 2

Check you troubleshooting items in Support link.

How much time would a technician need to replace a high limit switch on a Jandy Pool Heater?

Thank you for posting your question here on

It should only take a few minutes to actually replace the part; quite a bit longer to diagnose the problem depending on the way the switch failed and overall condition of the heater. It would not be unreasonable to get a bill for an hour to troubleshoot and repair a heater with a defective high limit switch.
