2476D Dimmer Problem

Had a power surge and one of the 2476D switches is making a high pitch sound. Tried to reset to no avail. Is the switch done?

There's a feature built into newer dimmer switches that checks for wiring issues or incompatible loads and sounds an alarm if either are found when power is first applied. If you change the load to a standard, line-voltage incandescent then power-cycle it, if the alarm doesn't sound, then you know the previous was an incompatible bulb or transformer.
