internal 3 point plug socket replacement

[Jetty]

I have dual sockets with usb (?) slots in my Leisuredrive Vivante... used mainly for kettle, heater microwave etc. One has gone very stiff to insert the appliance plug and the other impossible. I have read they can corrode. Can the panel be replaced ..2 small screws seem to attach it and is it a job for a complete amateur. Thanks in advance

Thanks. It is almost identical to this but anthracite grey

Replacing a socket like for like is very straightforward - the relevant screws are marked L, N & E. Take a photo of the back of the old socket before undoing the wires.
Only issue is if the conversation company did not leave enough wire to pull socket out 3 or 4 inches.
If you want to be sure that you have done the job right, invest a few £ in a socket tester.
