Our fridge worked well until one gas bottle ran out of gas.(manual changeover valve, gaslow) turned the second bottle on now fridge doesn't work. It just keeps on clicking trying to light. I switch it off to test for a while to try and reset itself but no it still won't work Cooker works so gas is coming through. Is it just coincidence? The surround of the fridge seemed to get warm yesterday but I thought it was just working harder because for the warm weather. Any ideas please?
