Lloyd-if it never reached 200v then you need a new board. I’ve never heard of 3 blinks from the led on the board. In fact, I just pulled all my reference books and there isn’t anything about 3 blinks. Are you sure it isn’t 6 blinks?
Did you unplug the refrigerator for a few seconds then plug in and do the test?
The 3 blinks have got me. I don’t have an answer for the 3 blinks. The compressor isn’t getting the proper voltage to operate so that tells us you have a failed PCB. I’ll keep researching the 3 blinks. It could be the bad board causing a strange blink in 3s but I’m not positive. I’ll post what I find.
