Check for 12V DC on both sides of the 3A DC fuse
Then check for 120AC at terminals J7 & J8 on board..........no 120V....new board
Also check the resistance of AC heater...unplug it from board. S/B 65 ohms.
Replace it.
Funny you should suggest that. I was just out there explaining to my 13-year-old how it works.
There was a wiring diagram on the circuit board cover - didn't notice that before.
And I was also able to determine, via google search, that the recalls have been performed on the fridge based on the type of eyebrow that's installed as well as the circuit board. I'm not surprised - the original owner was very meticulous with the maintenance.
3A fuse is good. 5A fuse is new. Need to check for voltage to the AC heater.
I checked for 120V AC on J8 and J9. Must not have looked at it correctly - wrong pair to check. Pop, blue flash and blown fuse. I explained to my son that this is NOT how you check for voltage. At least I won't need caffeine for the rest of the day.
Replaced the 5A fuse. Switched it to AC inside. Light does not illuminate. But.....heater works. I can hear the metal ticking as it expands from the heat. The AC light must be burned out in the eyebrow.
