Question about Hayward 100,000 BTU Pool Heater H100ID1 - Above Ground
It would seem that the thermal protection is kicking in because eiter the unit is overheating or one or both of the sensors are faulty.
You obviously know where the water pressure switch is, so follow the red wire from the switch to the heat exchanger. There are 2 identical "nuts"(temperature sensors) with a yellow wire connecting them. Once the unit has shut down open the it. Remove the red wire from the water pressure switch and also the red from the air pressure switch. Measure the resistance between these 2 wires. They should measure close to 0 ohm. If not then one of them is open circuit and may need replacement but you will need to test each individually to determine which one.
This in no way proves a faulty temperature sensor. It just means the unit is shutting down due to overheating.
Make sure there are no obstructions to the air flow in or around the unit as this could also cause overheating. Since this unit was working before and is not a new installation I'd recommend replacement of the temperature sensors.
