120Vac power is present on the control board but no light on the front Keypad nor was able to turn on the fan or Light from the keypad.

So, I replaced the Control board by following one;

However, now I am noticing a beeping sound from the board. I disconnected the Fan, Keypad connection & Lamp connections but still no change.

Both the boards look the same.
120Vac input power is present.
What else should I check?

Am I missing any setting or anything?

Experts;
Your recommendations please,

BYW, Anyone has the wiring diagram of the control board?

Thanks
