Hi, I have a Dimplex Loxley LXY15 and the lighting effect won't work. The heater is working, I have changed the bulbs and they are sufficiently tightened but still no joy.I take it there is a PCB in this appliance with a fuse in it, can anyone throw any light (pardon the pun) on the subject and what is the easiest way to remove the back cover, thank you.

The pcb will need changing it's accessed from the front,the glass has to be removed there are 2 quadrant strips held in by 3 screws a side

Light bulbs only require a simple switch to operate - a PCB control would make the fire overly complex and overly costly.

If your bulbs are of the screw-in type [ES] then consider that the central contact of the bulb may not be making contact with the central contact of the lamp holder.

If you slightly bend a holder's spring contact it may be a solution - be sure to have it unplugged - make yourself a small hook - use a mirror to look down the hole if necessary.

I offer this suggestion because it's happened to me - not all bulbs have the same dimension and the central contact can become bent and no longer touch a shorter replacement bulb.

But I only guess...

Good Luck..., November 2016
