Good evening,
As in the topic, the problem with the engine control board. Board number ELEW011.
The dryer came to me with the above-mentioned symptom, after the review of the board, I noticed a damaged R118 resistor that works as a fuse when the LNK364GN converter is damaged.
From the topic: link I concluded that the missing piece of the R118 is the Resistor 56K.
After replacing the inverter and R118, I connected the board and the relay on the main board clicks the voltage on the motor board, but the engine does not start. 3x 50V appears at the output of 3 transistors. I am asking for help from more experienced colleagues in the world of inverters. Below are photos of the board.
