New 75000btu beacon Morris heater humming noise?

I just installed my new 75,000 BTU beacon Morris heater. When the thermostat is off and the heater is not running there is a constant humming noise coming from the PCBoard. Is this normal or is something wired incorrectly. The humming noise is quite annoying.

I would think if it was wired wrong it wouldn't work correctly. You said the pc board is humming. Are you sure it's the board humming and not a transformer. Or is there a transformer right on the pc board. Can you see the board ?
