Pilot Assembly with Thermopile
The thermopile is a series of thermocouples that generate millivoltage through the Seebeck effect when heated by the pilot flame. Over time, oxidation or soot buildup on the probe reduces its efficiency, causing the millivolts to drop below the gas valve's hold-in threshold, which snaps the gas supply shut for safety.

Gas Control Valve (Honeywell/Resideo)
This specific model series often utilizes a Resideo gas control valve known for a high rate of internal electromagnetic failure. Even if the thermopile provides a correct signal, the internal logic board or the magnetic solenoid inside the valve fails to maintain the open position for the gas plunger, resulting in intermittent or total pilot loss.

Combustion Chamber Thermal Switch
If the water heater's intake air filter is obstructed by dust, oxygen levels in the combustion chamber drop, causing the burner to overheat. This triggers the thermal cut-off (TCO) switch, which breaks the electrical circuit between the thermopile and the gas valve, immediately extinguishing the pilot to prevent a fire hazard.
