ABB1922FEW2 Amana Refrigerator - Instructions

The vents at the back of the freezer were constantly getting packed with ice. A repairman failed to spot the problem. I used Partselect's web site to do my own analysis and determined that it was the defrost thermostat.
I followed the web site's instructions, which were exceptionally good. Behind the rear wall of the freezer was a lot of ice on the cooling fins and heavily encrusted over the old thermostat. (It was not really difficult, but I am in my 70s and no longer do things like this on my own.)
After replacing the part, I checked the ohms of the old part and found it to be faulty. Since then, the refrigerator has been working great. I wish I had started here. The repairman I had hired replaced the "control board" at significant expense. I doubt very much that anything was wrong with the old control board.
Many thanks to Partselect for an exceptionally helpful web site.

CHECK DEFROST THERMOSTAT WITH VOLT OHM METER AND FOUND THERMOSTAT BAD ALSO OHMED OUT HEATER AND HEATER CHECKED OK INSTALLED HEAT SRINK CONNECTORS ON NEW DEFROST THERMOSTAT PUT SYSTEM BACK INTO O
PRATION ALSO CHANGED WATER FILTER ON REFERGRATOR
SYSTEM WORKING OK AND NO ICING OF COILS THANKS WADE BOYLES

Removed the door and replaced the broken door closure bushing. I had courteous help and responce from Parts Select people. Excelent turn around time on parts delivery.

Remove rail and removed broken black plastic spring mechanism with new one and then replace rail.

Ordered new fan motor
Got part took fridge apart
Result was the motor was running
The fan blade had come off the motor
Replaced the motor anyway and reinstalled the fan, working well

Pop off vent cover remove 2 screws removed cover housing and foam. Removed damper by unclipping tabs on left and right side of control lift up and out. Unplugged power wires reinstalled in reverse order.

Easy fix, it's right in the back of the fridge under a cover that just clips in, a piece of foam, and two screws. The hardest part is getting the clips free without breaking them. After replacement it's silent instead of making a grinding noise regularly.

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.

Removed the 2 screws holding the light bulb shield, then the 4 uolding the metal panel. Unplugged the olw door switch and replaced.
reassembled the pieces.

Watched video. Unplugged refrigerator and popped out switch. In plugged connector and pushed switch in place. Plugged in refrigerator and the light worked

went on this website to fine info ALWAYS GO TO TYE OF APP. FIRST THEN TYPE IN MODEL NUMBER...THAT WAY YOUR GOING TO GET THE INFO ONLY TO YOUR APP. then search under symptom .." DO LOTS OF READING HERE ",CLICK ON COSTUMER REPAIRS thats were i found additional info on my problem..now on to the fix.. it stands to reason that on my appy. anyways that if the to parts plug into each other then you should think smart and get both avoid the coming "i told you so, you should have ordered the other part to" didnt cost that much extra... word of advice here .. i have big hands so when " they say" to plug both together then plug into the compressor...DONT!!!! plug the start device in first then plug in capacitor... almost forgot!!!! make sure ALL ELECTRICAL PLUGS AND WIRES ARE CLEAN-NOT BURNT ECT... used a can of electric contact cleaner-NOT ON THE NEW PARTS JUST THE COMPRESSOR AND THE WIRE THAT PLUGS INTO THE CAPAC. .. its just that simple... you will have to let the app. run for at least 24-36 hrs. to get cool enough and stabilize. after that we had to readjust the temp settings a little bit no bigee enjoy!!!!!

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.

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 first removed the bottom shelf. Then I popped the rail in. It was pretty easy although I did have to use some force to fit it in. Ordering the part and doing it myself was a lot cheaper than calling the repair man.

Very easily removed top shel glass above crisper--removed old rail by lifting up--and place new one in slots provided---simple!! Part was delivered in less than 3 days-------very fast and cheap !!!
