ABB1927VEB2 Amana Refrigerator - Instructions

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 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.

Popped off the control panel at the top behind the door. Found the thermistor and replaced it, cutting the wires and splicing the new one in. Immediately the warm section of the refrigerator was getting below freezing temperature readings, so the cooling vent was not opening. I put the old one back on and the temperature readings went back to being accurate. So this was not the problem. I believe now that the fan somehow is not blowing enough cold air up. So now I'll probably buy a fan motor and maybe a blade and try that. Otherwise the computer module I priced at $500 so I hope it isn't that. I replace the fan motor a few years ago already.

Unplug refrigerator.
Pry switch out with putty knife
Remove two wires from switch
Attach wires to new switch
Push new switch into slot

Remove the grate at the back of the refrigerator. Remove the existing drawn tube. Replace the exiting drain tube with the updated drain tube. Check to see if water was draining properly. Replace the grate. Sit back and have a beer.

The fridge would occasionally run warm, requiring me to turn it off and defrost the evap coils in the freezer. I found an online video that demonstrated the entire process of replacing the control board. The fridge model in the video was different than mine, so it took some time to figure out how to remove the panel. Once that was done, the rest was easy. The only tool required was a flat-head screwdriver that was used to push in the tabs holding the panel in place. The circuit board took more effort to split in two than I had realized, and I had to be careful not to bend any of the components on its surface. The whole process took less than 30 minutes, and the fridge is working properly now..

I initially tested the heating element and defrost thermostat using an ohm meter. the defrost thermostat was incased in ice, so I replaced it first. The refridgerator worked for about a week and then froze up again. I then replaced the thermistor and the unit is working as designed.

I followed the video provided by Part Select. I also let the refrigerator stay unplugged overnight with all the doors open. This p-trap kit has fixed the leaks out of the front of the refrigerator. There is no ice build-up in the freezer. Perfect!

I took a chance and ordered a switch that is next to the top of the door. looked for how to remove it easily done in ten minutes works fine last long time.

The instructions in the package were not helpful. They wanted me to cut the wiring harness and described where to cut based on the wire colors. My wires were not the same color! I removed the light mechanism using a combination of a screwdriver, putty knife, and plain old muscle with my fingers! The wiring harness unplugged easily and the new one inserted. It was easy to push the whole assembly back into the door. I spent more time looking for something to cut the wiring harness with (and never did find it) than the whole job actually took without needing to cut anything!

Disconnect plug from wall. Insert putty knife between light switch.and trim panel , apply pressure to depress plastic spring holding switch in place. Apply a slight twist too putty knife releasing switch from trim piece. This wil expose plug connected to switch. Disconnect plug from switch. Connect new switch to plug. Insert switch into trim. Plug refrigerator into wall socket.

DEFROSTED REFRIGERATOR COILS, BUT DIDN'T REPLACE THE GROMMET.

I made a temporary repair by drilling the old blade plastic hub and put a small screw in it to hold it on to the shaft until the new blade arrived. The new blade came in within the two days I needed before Thanksgiving. I removed the old and pushed on the new. There were 8 screws on the back guard and two to hold the motor on. It was a snap.
Thank you PartSelect.com The wife is very, very happy now, we had 51 coming over for Thanksgiving. :)

got the new part, took the old part out and snapped the new part in! Very easy. Thank you.

****Make are you order Capacitor & Starter relay too (we ordered separtely so had to pay shipping twice)**** Super easy just open access panel on back near compressor and remove retention clip with fingers, remove & replace both capacitor & starter, put clip and access panel back on, plug in and allow 8 hours to cool! Works like new again! Hope it goes another 10 years

Popped out broken switch with blunt flat edged instrument. Disconnected switch from unit . Plugged new piece in and reinserted into side panel of refrigerator. Very easy.
