Thanks for the previous answer. I was doing some troubleshooting and inadvertently touched the exposed aluminum portion of the fan. I got an electric shock. Measured the voltage between the metal part of the fan (and every one of the 3 wires on the connector) and they were all at 120 volt AC level with reference to the metal cabinet even when the machine was off. Every additional LOW voltage sensor directly connected to the main board was also at the same AC potential. On the other hand, the AC operated devices, water valves, heaters, etc were not showing any voltage with respect to ground. Continuity between cabinet ground and plug is OK. Wall outlet "polarity" is also OK. It looks like AC is present in the DC circuits, is that normal? Thanks in advance, Abel

ANSWER Hello Abel. No, there shouldn't be 120 volts AC at the DC components. You may need to replace the Main Board Assembly EBR32846821. Hope this helps.
