About 15 years ago a dimmer switch was installed in our bathroom. It controls a mirror with 7 light receptable. We use 40W in each receptable. I have noticed that the wall plate is warm to the touch after the lights have been on for a short time. The control knob feels normal and appears to be doing its job.
Should I be concerned about the warmth of the wall plate or is this normal?
Thanks for your advice.
