ABB1921 Refrigerator - Instructions

The digital display numbers (0= off and 7=coldest setting) controlled by the ECB would continually be replaced by straight lines, and the refrigerator would stop cooling. I tried unplugging it for a while. After plugging it in again, it worked (the digital display came on, I set it to "4" and it reached the proper temp), but the problem o ... Read more ccurred again the following day, and then it stopped cooling entirely. I ordered the ECB, and it arrived in 3 business days. I watched the installation instruction video, took my time, double-checked the vid a few times to make sure I was doing it correctly, and replaced the ECB by myself in less than an hour. The refrigerator has been running without problems for 3 weeks now. My fridge had a different light bulb configuration than the one in the video, but everything else was the same, and it was a simple repair.

I searched the internet for the correct part and reviewed the instructions on the internet. Upon ordering the correct part I was provided a link to a video that walked me through step by step. The very first thing I did was unplug the refrigerator.I then located the control board located in the housing in the ceiling of the refrigerator. ... Read more Using a screwdriver I was able to carefully separate the housing from the refrigerator ceiling . Unplugged the housing and then had to separate the plastic housing to locate the control board. Ran into a little difficulty at first separating the plastic tabs but with a screwdriver carefully pried the tabs. Once completely open is where the control board was. More plastic tabs holding the control board in place. Carefully separated the board from the tabs. The were two plugs that needed to be separated from the board. Used a screwdriver to get the plugs separated.The new board you had to bend carefully at a joint so the board became two pieces. Snapped the boards in place. Plugged the board in two spots. Put the housing together and put the housing in place in the refrigerator. Plugged the refrigerator in. All lights came on and then had to program the board. The instructions were spit on. The code is located inside the fridge were the model tag is. Programmed correctly. Word of advice read the directions a few times you can't go wrong. So far it's day 7 after I installed the board and no ice building up. According to the internet the control board controls the defrost function on my model. Very happy. I'm still watching the freezer but I'm pretty sure I fixed my matter. Thanks for sending the right part and the video. Repair went well. Just take your time and go easy because everything involved is plastic. I didn't want to break any tabs I had to deal with.

I replaced the control board first. The freezer back panel frosted up and the refrigerator warmed up again. Then I force (short option vs long) defrosted the refrigerator. However, a few days later the defrost issue came back again. Force defrost no longer worked, though likely due to a severe ice build up behind the freezer panel. I orde ... Read more red the wire harness. I took off the freezer door (loosen four screws only), removed the tray rails, ice maker, thermostat housing and vent mounted on the freezer panel. The rails and the vent are a bit tricky to remove since no directions exist. I then removed the fan above the coils and then removed the wire harness. Installing the new harness is easy except that I had to modify one of the ground connections for it to mount properly. I tested the unit for 72 hours. The defrost cycle eventually kicked in (dripping onto a pan and sizzling sound). I then reinstalled all parts. No frost build up. Good to go!

I just took the old one off and put the new one on..

Unplugged relay and replaced with new one.

We removed the old switch, unplugged it, plugged the new one in and it was easy to do. But when we tried to put the switch back in we had a very hard time doing it. Eventually got it in, but if it had not been for the difficulty we had getting the new switch to snap in to place, it would have taken under 5 minutes.

On the back of the refrigerator, I unscrewed and removed the lower-right panel. As I peeled the insulation off the panel, the insulation would disintegrate, so I used a vacuum-cleaner hose to remove most of the insulation. I removed the remaining adhesive with my fingers. I peeled the backing off the new insulation, and stuck it to the pa ... Read more nel.

I had ordered two pieces of insulation, hoping to also replace the insulation behind the compressor, but removing the compressor was complicated and risky, so I returned the second piece of insulation.

(1) Slide out appliance and remove power source. (2) Removed lower access cover on rear of refrigerator. (3) Disconnected plug to the condenser fan motor. (4) remove blades by pulling gently forward (5) remove mounting hardware holding the fan motor (3 screws) (6) motor is now free and new motor can be installed

The other guy described it perfectly so all I can add is that this repair was as simple as they come. Don't hesitate.

I have replaced the circuit board, the condenser fan motor but the unit still will not feeze correctly. The bottom of the unit freezes but just barely cools the rest of the freezer and ice box. Have you got any other advice that might help. This is a side by side unit. What else could be the problem. It seems that the fan is not workin ...

First I removed the back cover then removed 3 nuts holding the motor. Next I removed the two wires. Next I attached new connectors to the wires and installed the new motor and everything worked perfect!

Service and shipping were fantastic! I would definitely use Partselect again!

Followed the video and installed the new Jazz board. The board cam in 1 piece which had to be separated into two pieces, but the scored area on the board made it less intimidating. At the same time I replaced the two incandescent lamps in the refrigerator area with LED lamps. Getting the housing for the control board apart was the most ...

My son (who does HVAC, but not appliance repair) did some investigating by taking front and back panels off and determined that the evaporator coil was freezing over because the defrost wire was not heating up. He and his girlfriend did some real-time internet searching for diagnostic info because NO control diagram was included with the ... Read more refrigerator. He determined the problem was most likely the electronic control board. Ordered and installed a new board and the refrigerator is back to working fine. Took about 2 hours to diagnose the problem and 1/4 hour to actually install the control board. Kind of disappointing that this control board failed when the refrigerator was less that 4 years old.
