I am replacing my bathroom extractor fan which is a S & P 250/100 which has a timer with the silent version that does not have a timer. The old one has 4 wires red/blue/yellow/earth but the new on only has connectors for the live and neutral. Can anyone help me with the wiring here?

There are two possibilities here,

1. it is a mechanical failure i.e a part of the linkage has broken leaving the switch in the on position, did you see anything obviously wrong with the old switch?

2. It is an electrical failure either overload or arcing when the switch is being operated sometimes welding the contacts together. This can happen if the light is a fluorescent tube or ring type, which in combination with the fan start up, can cause this situation. If this is the case you need a higher current rated switch.

Please remember to rate this solution.

SOURCE: Nothing to attach a ground wire to.

ground wires are normally attached to the electrical conduit or box grounded means to earth in electrical terms so any ground terminal available can be used hope this helps

double check under cover there is usually a blue and white for light & red and white for fan. probably tucked under housing to far to see

SOURCE: The 3-way dimmer switch has 4 wires; 1-red,

Incoming white - outgoing white This is the neutral, which just passes through without connecting to the switch
incoming black - switch black the hot wire provides power to the switch
switch red - outgoing red a traveler, will have power when toggle is one position
switch yellow - outgoing black
the other traveler, will have power when toggle is in the other position
incoming bare - switch green - outgoing bare the switch is grounded and it passes through

OK .. the thick black and white are the power for the fan , are there also white wires on the lamp sockets ..??
The thick black wire should connect to the black wire on the switch.
The small black wires connect to the red and blue wire on the switch .. two small black wires each .. that should give you a position for 2 lights , and 4 lights, on the step switch .. but there should be white wires from the lamp sockets connected to the thick white from the fan .

please respond .
