Hisense refrigerator frequency conversion board driver board BCD-209BP/219GBP/203/232VBP/258VBP

New Hisense refrigerator Frequency conversion board driver board BCD-209BP/219GBP/203/232VBP/258VBP There is no need to change the socket, the socket is exactly the same as the socket on the original board, and it can be used directly on the machine. A brief introduction to the method of judging the frequency conversion board:

1. When the inverter board is damaged, the compressor will not start, the digital display of the display panel is normal, the refrigerating lamp is normally bright, and it is not cooled!
2. When this problem occurs, first check whether the 220V input of the inverter board has input. If there is input, measure the frequency conversion signal 2.1V-2.5v. Normally it is 2. 3V. It is normal in this voltage range because of the error of the table.
3. The frequency conversion signal is also normal, indicating that the pre-stage control is normal, and the problem lies in the inverter board and the compressor.

The multimeter selects the AC 50V file, measures any two wires of the WVU, plugs in the power, and the normal frequency conversion board will output a small voltage detection compressor when the refrigerator is just powered on. Generally, the AC voltage between 10-50V is instantaneous, no Output, change the frequency conversion board, only 3 lines of output on the 3 lines are also the problem of the frequency conversion board. All three lines have output, so consider whether the compressor is a problem. You can try to replace the inverter board. If you change it, you can change the compressor.
