Introduction

I show you how to tear down the DW15s WIFI switch and I show one potentially common problem with these devices. Many of these devices use cheap capacitors and when they start going bad they can cause all sorts of unexpected results. This is just one example of how to diagnose and repair them. Of Course there are many other things that can go wrong but this is probably the most likely problem when they act up.

    • Take a look at this video for tear down and repair instructions.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Hi there. I actually opened mine up and the capacitors were 3.3 uf and 450volt. Weird

There are high voltage caps in there but those are not the ones that fail normally. You’re looking for low voltage high capacitance caps that are the electrolytic type and they will be larger and looks like a barrel.
