The ZD-95(G)F is a small-form-factor PCB that functions as an AC-DC converter. It is characterized by a robust design tailored for longevity in high-temperature environments (like water heater casings).

Find the feedback loop on your schematic. Test the reference zener diodes, the TL431 precision shunt regulator (if present), and the optocoupler. Additionally, examine the equivalent series resistance (ESR) of the output smoothing capacitors. Intermittent Thermal Shutdown Laptop Motherboard Circuit With Schematic Analysis

Before searching for the schematic, it is important to verify exactly what the ZD95GF is, as part numbers can often be misread or abbreviated on silk screens.
