    battery pack question

    It all looks good inside. There is a bit of moisture stain on the insulating paper top and bottom, there are 15 1.2v 1300mah cells in series. I put a pair of the cells in my ever ready ni-cad charger, but that amperage is not proper and it started to overheat, so I pulled them out. I don't...

    diagnostic port on smartkegger control board.

    Freedom is a strange thing indeed.... so too is beer sometimes! It seems to me that until the smartkegger project is complete and operating that it will be dry around here, and of course the project must go on if I am to get my Oktoberfest beer made... Anyway, its working. just not reading out...

    battery pack question

    What are the chances that every cell in a battery pack would fail all at once, and that all of them would not take a charge?

    diagnostic port on smartkegger control board.

    Brother in law is a Viking... I took the boards out, but put them right back in because they are all working properly. I have to replace the refrigerator sensor, the freezer sensor, and probably a switch somewhere... What I am saying is that this $3000 fridge just needs a few sensors replaced...

    diagnostic port on smartkegger control board.

    Good kick pants... On with the show. 20 pins, always have a pro do the big thinking for you! I can measure various sensors with it... so if I had say an 8 channel digital scope I could probably read the sensor values and find out whats causing my problems? But of course the board would have...

    diagnostic port on smartkegger control board.

    The LEDS are on a different line than the freezer sensor, and the door open alarm blasts all the time when its function is turned on. I connected my Wi-fi and found that the fridge sent the message Door Closed, then after I tested it, the message Door open re-appeared and it is bong bonging again.

    diagnostic port on smartkegger control board.

    Got some pics for you. First pic is a pic of the cameras inability to take pics of the board without the flash... Second pic is a general snap shot of the board itself. third is the port in the center of the board.. upper left is the QR code in the previous pic. fourth pic is the failed freezer...

    diagnostic port on smartkegger control board.

    So a simple breakout box is probably the best place to start if its failing? Problem is it doesn't appear to be failing... I have decided to change the thing thats producing the wrong panel readout... the freezer sensor.. it reads 46 degrees when the freezer is between 0 and 20 farenheit...

    Fridge compressor test....

    I recently discovered that there are a few different types of compressors and some use a linear motor that only shows continuity on 2 of the pins..... so your compressor might not be bad, if its testing dead on 2 sets of pins...

    How many keys in AES?

    guessing 12.

    diagnostic port on smartkegger control board.

    There is a rectangular port with about 12 to 16 pins that I would say is a loading, unloading port for the eeproms and the system. Just worried I might juin everything else if I hacked in... Anybody know what kind of system and interface the old Samsung smart fridges were loaded with?

    diagnostic port on smartkegger control board.

    What kind of scope would I use to diagnose this fridge board, a standard oscilloscope? Or does it take a special 1000.00 scope from samsung!??

    General Shortouts and Opens

    My rule of thumb is white to white, brown to brown and red to red, it didn't really include any white/yel stripes or purples and pinks in the same terminals on the connectors that connect to grays and whites! ( Alien asumptions can cause severe shocks on reworks )

    General Shortouts and Opens

    I looped the test wire around the fridge to test the continuity of a white/yellow wire I found on the board. great continuity there, it is definitely connected somewhere in the case 1 ohm. Thats really good continuity! So when I trace the circuit through what is supposed to be the optional...

    First generation devices with rework and frequency adaptation

    I have bought a few of these after market devices that are very useful but have been discarded because they are reworks and some have quirks, jerks or shocks that they ended up with, in the reworking. Most failed because of bad or wrongful manufacture of a piece of the device that connects to...

    First electronics repair question

    noteworthy... "It's a diode, a capacitor and a motor". You could say its a switch, a battery and an inductor, try to wrap your head around that!

    wiring diagram does not match...

    Works for 15 minutes 'isn't that long enough?' . yep. plenty long. I would say asian retribution for WWII! wow, what a temper!!!

    wiring diagram does not match...

    wow I knew there was something funky with my thermistor! So assuming these rich engineers are to cheap to use thermistors, the conditions are kind of like... "Oh Oh our new invention has been wired wrong and the programs are failing what should we do...???" So they call YOU guys and say...
