Just after a bit of advice here guys.. we have a chest freezer in the shed bottom of the garden and last week my other half said she got a shock... though she was a drama queen until I went in it tonight and I got a shock, it feels as if static electricity, just like a zap.. all electrics in the home have been rewired in the last 5 years so all ok there .. the freezer is getting a bit old so if dodgy I will unplug and get a new one
