Re: Whirlpool Refrigerator LED lights flickering
I did see a caution with the Whirlpool AC/DC LED power board- if you power it up and then connect the LED string, it blows up the LED's.
It seems you must have a load on it (at J2) or the output capacitor charges to high voltage.
This means a flickering LED would surge everything and basically beat up the LED's.
11-14 Volts DC is normal for each auxilliary LED board at their J2. 4 LEDS in the freezer LED module, and 4 LEDS in the crisper LED module. So that string is 22-28VDC. You can test each aux module with a bench power supply at ~12VDC and a 100 ohm series ballast resistor.
There's 4 LEDS in the "diamond" main AC/DC LED power board and I'm not sure where they are in the picture, if it's a triple-series 33-42VDC string?
