Web26 nov. 2007 · 1,939. broken capacitor. This is not a capacitor, it is a varistor that offers protection from high voltage spikes. If you ommit it the power supply will work fine but no protection from voltage spikes would exist. You can replace it with a new one provided it is for the same voltage levels that it triggers. Web22 nov. 2024 · The Varistor is there to ensure that any load dumps / vehicle transients will not result in catastrophe for the circuit. My question is this: Should I pass VIN through the Varistor, or should the Varistor couple VIN and GND? Circuit A has VIN passing through the Varistor: Circuit B has the Varistor tied from VIN to GND: dc varistor Share Cite

Your overvoltage event undoubtedly burned out the varistor so it appeared as an open circuit. This prevented the AC from turning on. When you bridged the varistor with your multimeter, you inserted some resistance in the circuit which was enough to allow the AC to turn on.
