Add up all the wattages from the lamps that are controlled by the dimmer
that is getting hot. Next, remove the face plate of the dimmer an see what
the maximum wattage is (typ. 600w). If you are exceeding the maximum
wattage, you should reduce the lamp wattage by replacing the bulbs with that
of a lower wattage.

Also, you may find the wattage below the capacity of the dimmer. It is
normal for them to be quite warm when there are several hundred watts of
load.

I have 3 dimmers in my house that are the same model dimmer. Have them
controlling ceiling lights. Two give of very minor warmth generally
during operation, while one gives off so much heat that the screws
holding in the face plate are almost too hot to touch.

Is this likely a bad switch? Just get a new one? Worrisome as it's
housed in a plastic box, not metal.

Thanks.
