We have a dimmer switch powering four GU10 halogen bulbs.
The other day, the lighting RCD tripped and I bulb had blown. No problem when I re-set the RCD except that, whilst the switch still turns the (remaining) bulbs on/off, it no longer dims them.
Is there some obvious reason for the loss of the dimming facility?
