Pool Heater High Temperature Faults

A high-temperature fault deserves investigation of the conditions around heat transfer, airflow, water flow and combustion before parts are selected.

What matters during diagnosis

Do not assume the sensor is defective because the display reports a temperature fault.
Restricted water flow, fouling and operating conditions can influence temperature-related shutdowns.
Repeated overheating or limit faults should be diagnosed before continued operation.
Model-specific testing belongs with a qualified pool-heater technician.
