There is not a way to verify that a new board is good or not. AS far as testing and diagnosing a control board in a unit goes, the best test is power in and power out. At the J1 connector at the board. You are checking from line to ground at black and green. Check from black to light blue which is pin 1 and 3. This is line and neutral. You should get 120v. If not your loosing a neutral somewhere. Go back to the outlet and check to see if you have proper voltage. line to neutral and line to ground should be 120v. neutral to ground should be 0v . There is a diagnostic mode on the tech sheet, but I most likely will not work with the unit not powering up. The unit should start up after plugging the unit back in after the repair. I have seen any communication errors on these units that usually result in the main board being the fault. Its a communication error between the UI board and main board. Above I have attached the tech sheet previously if you need to take a look at it. IF the inverter board is bad it should not cause everything to shut down. Power piggy backs off of the inverter board to the main board so it should not make a difference. Going back to the main board you installed. I show that is not the correct part number you installed. The main board on the bottom of the unit is 241996361. You may have installed the wrong board. The part number you are providing is coming back as invalid. not even listed as a part. I have installed this board before and pinched a wire which shorted out and caused the new board to go bad. IF you had a power surge to this unit it could have also taken out multiple boards. I dont think extending your time will be an issue. I will check with my manager.

    Brian,. . . way to go!!!!! Blue wire was loose in the connector . . . reseated and refrig is working fine. Nice !!!!
  • That is awesome. I’m glad we got it figured out! Sorry again, that it took longer than usual for some of my responses.

Sorry. I responded to this a few days ago, but it never came through. The part number(2411996363) you provided for the main control board on the bottom if the unit, that is accessed through the front is not valid. The number I provided in my first answer of 241996361 shows to be the correct one. If you have power to this main control board, the next thing I would check and suspect to be your issue is the refrigerator control, 242048309, located on the door when you open it. Looks like power is sent to this board and then this board controls the cooling operation and maybe more. Here is also a link to the tech sheet on this unit. It has the diagnostic information and wiring schematics.

    Brian, Should I email you or txt when I respond.?
  • I did get notified on both of your responses today. If there is every an instance in the future that we do not respond to you with in a couple of hours during the normal hours, please email us and let us know so your not waiting again. On the JA9 connector, it shows pin 1- red- (12v+), pin2 – white(common), pin3- black (ground). So you should have 12v from red to white. Also, 12 v from red to black. If so the main board is sending voltage to the UI board. Check at the same connection at the UI board to see if you get 12 v at the UI board. IF not you have bad wires somewhere between. IF you do get voltage to the UI board then It sounds like the UI board is bad. Is the UI board separate from the Refrigerator control board you replaced?

    JA9 No voltage Red . . .
  • Your not getting any voltage at the main control board at the JA9 connection? This would mean the control board is not sending power out for this circuit. You have said you already replaced this control board and have checked for 120v incoming voltage to this control board correct? Make sure you have 120 coming in properly to the control board. If so we could have a bad connection or pinched/ broken wire. Check through your wiring and connections at the board. You can also check some other test points on the board to see if it is sending power to any other components. I notice you stated the part number of the board you replaced previously and I found that board to be a different part number. Verify you have installed the correct part as well.

    Known 1- Power is getting to the board at J1 Blk and Grn/Yel 2- No output at J9a confirmed by no lights on display Next Step Is there a fail safe mode or test mode for the board. .. . like how would you know if a board was good or not. . . other than putting it in a refrigerator? Is there a startup sequence that is being interrupted? There is a flow chart on the tec sheet for communication with the compressor inverter board. Main Control board is to be sending 10-15 VAC and 1-5 VDC to Inverter Board. There is a Blk/wht and Red/blk. I am getting 3-4 Volt DC when check this pair. If the inverter board is bad . . . does this shut everything down? Big Picture 2411996363 the original and replacement board could both be defective? What are the odds of that? In your experience is there a situation where boards are being damaged? So putting in a new board . . . only damages that board as well? There must be some history of this unit you can draw on. My time is up on the 21st can this be extended because of the communication issues? Regards, Mark

Hi. Was 241996361 the control board you replaced, that is located on the bottom of the unit? Your still not getting any lights, display or anything? It looks the the User interface is located on the Left door when you open it. Is this correct? The main board on the bottom controls most everything. That’s strange that it still has no lights or anything if this is the board you replaced. Let me know.
