The touch operated switch on our LT100 panel that should switch on our 12V, seems to have died. It briefly developed an intermittent fault, not always switching on and now won't do anything. All the various level indicators work and we have power to the fridge which is not switched by the panel. Has anybody experienced issues with one of these? Will I just have to bite the bullet and get a replacement panel, or is there a cheaper fix? Thanks in anticipation.
