Great,it's always easier to help someone who has the skills to test. As you say it could be a board fault but its quite unusual for that to be the cause of the fault.
You need to start at the gully where the frost drains into when defrosting. Clear all ice away and ensure that you can pour hot water in and let it drain away. It drains through the back of the fridge freezer where it collects in a tray on top of the compressor and then evaporates from the heat of the compressor. Where the water leaves the drain tube to drain into the tray there will normally be a rubber spout, check that it has not welded itself together with the heat of the compressor.
There is a defrost heater and thermal fuse attached to the evaporator inside the the freezer compartment. Test the fuse for continuity https://www.4ourhouse.co.uk/search.pl?query=KGU3201GB%2F07+fuse
Also check the for resistance across the element https://www.4ourhouse.co.uk/heater-defrost/product.pl?pid=923608&query=KGU3201GB%2F07+heater
If the thermal fuse or element are open circuit they will need to be replaced.
Sometimes the build up can simply be caused by a build up of scale in the drain tube causing a blockage and just cleaning it out will solve the problem.
