Whirlpool 12002355 Refrigerator Defrost Thermistor Kit OEM Part

Toughest part of this repair is figuring out how to get things apart. Amana doesn't provide you a repair manual showing how to disengage the various plastic covers. Initially disassembled the bottom freezer compartment so I could get to the evaporator coils; they were completely frozen in block of ice, restricting air flow to the fridge above. Obviously, the auto defrost cycle had not been running, or was short-cycling. Manually defrosted. Found this link for running diagnostic tests on the JAZZ control board: http://applianceassistant.com/Refrigerator-Repair/W10503278-Refrigerator-Control-Diagnostics-Repair.php. Useful set of tests. Defrost circuit test passed, but defrost obviously not working, so suspected control (JAZZ) board [high failure item based on other reviews]. Replaced JAZZ board, but to be on the safe side, also replaced both thermistors and the defrost thermostat while I had everything apart - hence the long repair time. Appears to be working again now. Control board was actually the easiest part of the repair, once I figured out how to get to it. For others with this model: 1) Remove light cover by sliding it toward the back of the fridge; 2) remove the light bulbs; 3) Open control board compartment by using flat-blade screwdriver to disengage two plastic tabs on back side of compartment (this is the tough part); 4) Cover will hinge down and you will now see the control board (and the fridge thermistor, should you choose to replace it too); 5) Note how the old board is actually two pieces, the display being connected by a ribbon cable to the main board - when you get your new board, it will be flat - you need to very carefully separate the display along the scored line on the board to extend the display cable and orient the display properly - be very careful and support the main part of the board on a solid surface while you gently flex the display portion to separate it; 6) Disengage old board and display from holder by releasing retaining tabs one for each section; 7) Center new board on the supports and engage retaining tab; 8) Reassemble everything by reversing steps 1-4 and you're done. If you choose to replace the temp sensor (thermistor), you will need to cut the old one out and splice the new one in (wire nuts are supplied in the thermistor kit), but the control board is much more likely to be at fault based on all the reviews I have read. I ran resistance checks on both of the thermistors and the defrost thermostat I replaced, and they all checked out good - I could have just done the control board and probably solved my problem, but we don't have a backup fridge and I didn't want to disassemble everything a second time.

I replaced the thermistor and the damper control. I couldn't have done it without the videos showing me how to get stuff apart

Whirlpool tech stated it was the main control board, he changed it twice over a 2 week period and it was still running. The tech stated this was "normal", I felt otherwise, so I noticed that it was not the compressor, but the evaporator fan that was running all the time. I tried changing the settings to a warmer temperature and this did not stop the running. I figured it was either a bad thermistor or the evaporator motor not circulating the air correctly. I bought both parts and changed them out, it took about 1hr total and the fridge is back to normal. The parts arrived in a couple of days from ordering and the videos online helped locate the areas where the parts were located in the fridge.

They said it was either the thermistor or the compressor start device. I wasn't sure which one it was so I ordered both parts and replaced both of them. Both were extremely simple to replace, seriously about 5 minutes was all it took to replace each part, so 10 minutes total and I was finished and my refrigerator and freezer were working again. They also have videos with each part that'll help show you how to repair certain parts.

Replaced Keyboard Control Touch Panel and Refrigerator Thermistor. Video was very helpful on how to change.
