I opend it up, and it was a little wet inside. I take the circuit out and i see that there is one resistor black, i check it whit multimeter and it's not conductive.
now i desolder it and i want to replace it but i dont know which must be, because i dont see al the lines on it.

Can someone can help me figured out whitch want must i replace.

Thanks

Re: Milk warmer problem

This is a weird design.
Looks half cap and half res coupled transformerless design.

This resistor should be a flameproof, and my first guess would be 680 ohms 1/2 watt.

Again this is only a guess.

Most likely the rectifier ic on the bottom of the board is also toast where the B+ is. I wonder if D1 is bad?

Re: Milk warmer problem

Probably shorted when it got wet.

You could clean up the resistor with alcohol or such and then measure each burnt half resistance, then add them together. That will give you a rough idea of the resistance.

680 Ohms does make sense though.
