Perhaps some kind person can help me.
A Japanese made handheld massager was plugged into a 220 volt AC supply in error. I have managed to open the casing and look at the circuit. I found that a thermal fuse had failed and therefore replaced it with a very similar value. Tested it on a 110 volt AC supply and the thermal fuse failed again.
I disconnected one of the AC supply leads to bypass a small circuit and the machine worked in slow and high speed. The fault therefore lies in the small electronic circuit. I have hand drawn the circuit and my guess is that the choke/inductor may have failed, but I am not sure.
Can anyone offer a point of view please.
