How to fix Electrolux ER9092B flashing display
Introduction
Warning! The circuit is fed directly from the mains. Use an isolating transformer and observe the usual precautions.
This fridge has a PCB manufactured in Italy. The fridge works without said PCB, whose sole purpose is to provide temperature measurement from the freezer and temperature alarm. The PCB has two small microprocessors that are fed from a 5V supply. The 5V supply id derived from the mains by a rectifier bridge and a series capacitor. When this capacitor’s value drops the voltage drops. This is detected by the processors who do a brownout reset. They now draw less current, so the voltage rises, the processors start, voltage drops and the process repeats.
