ABB1922FEB2 Amana Refrigerator - Instructions

First, turned off the circuit breaker. Then: 1. Removed all food, , wire sliding baskets, and the ice bin.
2. Removed ice maker by removing the electrical connector from the socket in the rear panel, removed the single bottom screw with a 1/4” nut driver, loosened the 2 top screws with a 1/4” nut driver, and lifting the unit up and off the 2 loosened screws.
3. Removed the freezer door by loosening the 4 screws( 2 on each side) with a 1/4” nut driver and then lifting the door face off the loosened screws.
4. The next task is to remove the panel at the rear of the freezer compartment: use a flat blade screw driver to compress the side clips that hold the ice maker electrical socket, pushing it into the space behind the rear panel, then removing the rear plastic cover in the center of the rear panel, and finally removing the thermistor cover on the right rear upper corner of the rear panel( separate the thermistor from this piece, threading it through the slot in the top of the plastic cover.
Now, the rear panel can be removed by removing the 4 1/4”” hex head screws with the nut driver and gently easing the panel from its position.
5. Now comes the hard part: the defrost thermostat and most of the surrounding “plumbing” was encased in ice. I used a hair dryer to melt the ice, which created an overflow of water drawing into the collection pan; get ready to mop up this water.
6. With ALL the ice melted( this took over an hour), I simply cut the 2 wires, stripped the feed ends, removed the defective unit, clipped the new thermostat to the copper tube where the old unit was clipped, cut excess wire/stripped the new wires and used 2 orange wire nuts to connect each wire.
Now all the parts and pieces can be reinstalled in the reverse order

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

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.

Info on your site allowed me to determine the most likely cause of the problem, defrost thermostat, and that fixed it. Good installation instructions on the site too. Part was super easy to install. Hardest part was removing the snap-in/screwed-in plastic parts that held the sliding baskets and back panel in place. Didn't break any.....Thank You!

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.

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

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.

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.

Total time 10 minutes. 9 minutes to clear out the food and 1 minute to install the part. Installation was self evident and could have been done blindfolded. Part just snapped in.
