Will try to keep this brief. I have 2007 Hymer B544 The Fridge is Dometic RM7655L. after the winter I found that I could not turn on the fridge at all. No lights on display, no ticking to light gas , absolutely nothing. I have checked and replaced the external. 12v relay. I have metered the 240v supply at the PCB and there is power. I am suspecting the PCB may be faulty. any suggestions would be greatly appreciated.
