Flat blade screwdrivers, Phillips head screwdrivers.
Freezer cold / refrigerator warm. Jazz board with adaptive defrost malfunctioned.
My Repair & Advice:
Slide back clear light lens toward rear of refrigerator. Insert flat blade screwdriver into recess that holds 'light module' into upper housing (I removed forward upper door latch and then entire control unit assembly). Exercise caution to not break plastic housing. Assembly was easy to perform. *If refrigerator is warm and freezer cold, evaporator coils will be frozen in freezer (assuming cold air door functions in fridge)Make sure there are not any excess items blocking airflow in freezer. Defrost freezer and function should return to 'normal'. If it ices up again (ours took about 2 weeks)replace controller board (Jazz Board) These units are prone to fail unfortunately.
Refrigerator stopped cooling; freezer coils built up ice. Freezer continued to work.
My Repair & Advice:
Easy replacement, except for figuring out how to get the light module off and the assembly out. The slots connecting the light module to the upper housing are at the rear of the module, and difficult to see. If you don't remove the light module, you have to almost climb into the refrigerator to get at the jazz/control board when it's still attached. We also took off the door latch, and removed the whole assembly. The assembly is wedged in with barbed catches that are hard to find and release. We ended up slightly bending the plate to release them, rather than trying to wedge something in to press them back. Once this was done, replacing the jazz board itself was easy, and it fixed the problem.
I had a Sears service tech come look at my 3 year old Kenmore fridge. He did several tests, made a phone call, and told me my control (jazz) board was keeping my freezer compartment from defrosting. $225.00 but would have to come back. I gave him his service call fee and ordered the control board. He did show me how to access it. It is in the compartment behind the top door light switch. Remove the lens and it all snaps apart from the rear of the assembly.There is one more plastic plate that holds the board inside. Unsnap that and you will see two ribbon cables going to the circuit board. I put the new board in place and defrosted the freezer manually. After running for a week my refrigerator was warm again. I also have now replaced the defrost thermostat which I read about on other forums. I wish I would have started with that rather than listen to the service tech from Sears.The defrost stat is located on a copper refrigeration tube behind the plate in the freezer. You have to remove the ice maker, (4) 1/4" screws and unsnap the cold air vent. You will see it on the right side clipped to the piping and it has an orange and brown wire to it.I just did this repair yesterday so I am keeping my fingers crossed.Parts Dr. has given me great service.
This was the second time the control board had to be replaced. The fist time we had a repair man do it and it cost 200.00 dollars. I kept the invoice and found the part number and found Parts Dr online. Ordered the part and with the helpful tips on the site I was able to do it myself saving 120.00 dollars. Thanks Part Dr!!
Instructions that came with the Control Board on programming the Control Board should have said to close "both" light switches not just the Fresh Food light switch. Not knowing which door on my French door Refrigerator was the "fresh food" side I tried both separately but couldn't program the Control Board. It wasn't until after both light switches were closed simultaneously was I able to program the Control Board. Compressing the plastic snap to remove the drop down panel was the hardest step. The snaps are very rigid and compressing them enough to disengage allowing the panel to swing down boarders on breaking them. It would a lot if the ends of the snaps were blunt rather than tapered. The tapered ends are almost impossible to push on.
