Refrigarator board repair and check for short cirquit
Hello
Whirlpool ARC 8120 refrigerator-freezer.
Every few seconds, a "beep" sounded with the lights on and off at the same time, with a failed attempt to start the compressor (accompanied by a "click")
What did I do ? I changed the permanent capacitor (5μf, 400Volt).
Result: The compressor was starting, but the "beep" -opening of the bulbs continued its presence.
Action: I changed the three electrolytic capacitors of the board - 1000μf 16V, 470μf 35V, 10μf 50V.
Result: Nothing.
Next action: I located the source of the "click", ie one of the two releys, which after being checked and found to be defective, I changed it, but without any result.
Then I started and started changing smd. First a 10kΩ resistor, and then 8 capacitors.
Somewhere here ended my attempt to repair the board because as the tools I have are a soldering iron with a not very thin nose, a magnifying glass worn on the head, tin, solder, desolder, in my attempt at three of the smd capacitors (size 1 to 2 mm) detached (destroyed) the one base (of the board) on which it rested on the board. In one of them I found a path that connects it to a point where I can stick it with an extension. In the other I do not know where it was connected before its base was destroyed, and in the third the same as the first. The base was also damaged by an smd resistor located just after the first two capacitors (without knowing where they were connected).
What am I thinking of doing?
Since I do not know any way to repair the board anymore (if anyone knows, glad to hear), I decided to buy a new one, at a cost of € 150.
I'm afraid there is a short circuit in the refrigerator and if I connect the new board it will be damaged.
The technician I asked to come and check the refrigerator for a short circuit, asks for 40 €, which I do not have.
Is there a relatively easy way to check the refrigerator for a short circuit?
I am sending a photo with the damaged (from the repair attempt) parts of the board, and the back of the refrigerator.
At the back of the refrigerator with a multimeter and at the indication for "continuity" I checked the socket on both poles without hearing a "beep". The socket ends up in the white box with the yellow label. This and the other white box, fasten on the board.
Also, with the multimeter, I checked the other white box (its two sockets), but here it sounds "beep" from the continuity of the multimeter. This box ends in the compressor sockets.
Thanks for any hint.
Es esta una buena pregunta?
