I've been told they have big scary capacitors in them as well. Never fun trying to fix something where unplugging it isn't even enough to be safe.

- bestham 4y agoI’ve yet to see a home appliance without a dropper resistor across the Cap. Even the worst penny pinching Chinese knockoff PSU has this.
- ClumsyPilot 4y agoWait for a few minutes before opening it up, check with a multimeter, etc. Mains voltage isn't that scary if you follow basic precautions
- kadoban 4y agoIs a few minutes enough? My impression was they could remain charged for long periods.
- MertsA 4y agoA few minutes is more than enough under normal conditions. Modern electronics all have bleed resistors that drain any dangerous capacitors when the device is off. In microwave capacitors the bleed resistor is built into the metal can of the capacitor itself. You should always assume capacitors are charged unless proven otherwise. Just grab a screwdriver with an insulated handle and short out the capacitor before assuming it's safe.
