My refrigerator is freezing everything but the freezer is working fine. The coils in the back and the bottom have been cleaned. Do you have any further suggestions? Thank you!

I have a couple of issues that I am wondering if are related. A few weeks ago, the lower part of my refrigerator began freezing up, even on the lowest setting. Freezer seemed to be working fine. The water dispenser quit working at the same time, which I thought was due to the water line freezing since it runs through the bottom of the fridge. Then the ice maker quit too a few days later - the on/off lever is stuck halfway up and will not release. Could problems be related? I replaced the water inlet valve ps7784018 about 3 years ago and again in may of 2017, both times because water dispenser quit and it fixed the problem both times. But the refrigerator was not freezing things then. I did clean the coils after the first day of the problem and it didn't make a difference. Unit also started making a clicking sound this summer that seems to be part of the ice maker cycle.

Hi Jennifer, Thank you for the question. Sounds like the water lines and the ice door chute are frozen as well. If you fix the issue with the fridge being to cold it should also fix the dispenser and ice problems. I would start with the Defrost Thermostat Kit. With the issues you are having this is the most common part to be replaced to fix the issue. Hope this helps!

Fridge quit cooling, blowing warm air. Purchased thermostat replacement and replaced; started cooling again for just a few hours, but now blowing warm air again. All fans working. Is control board the culprit?

Roy for model number frs23hf5aw5

Ho Roy, Thank you for the question. It is a good idea to check the Adaptive Defrost Control Board. This seems to be a common part when the freezer is working and fridge section is warm. Hope this helps!

Refridgerator too cold adjustment no good.

First I replaced the Defrost Thermostat on the coil and this did not fix the problem. So I ordered this new ADC (Adaptive Defrost Control)board.
It is not identical to the first ADC board and at least one feature the old ADC did was deleted from the function of the Fridge. Not sure why?
Because the board were different a new wiring harness was provided.
Step 1. Unplug the unit and remove the water filter.
Step 2. Remove the covers off of the unit on the top of the fridge using the 1/4" nut driver and a 1/4" deep well socket with extension for the deeper inset fasteners. This exposes the wiring harness and the ADC board as well as the temperature controls.
step 3. Remove the screws for the ADC on the cover and remove the wiring harness from it. No need to note the wire's positions as the new ADC uses a different connector.
step 4. As you remove each connection of the wire harness from the unit replace that connection with then new harness connector to eliminate any confusion. Do each one. One by one until the old harness is completely loose and the new harness is completely installed.
step 5. Install new ADC which in my case was now enclosed in an orange case. Unlike the one I removed that was and open pcb.
Step 6. Replace covers using the 1/4" nut driver and 1/4" wrench.
Step 7. Replace filter and plug in unit.

Apparently there have been 4 versions of this ADC board through the years. My fridge was built in 2003 not long before I bought it.

Bottom of frezzer cold...top warm...refrigerator warm

I first located the wiring diagram under right frt. of fridge. Using it I troubleshot the problem to be the ADC module. I ordered the ADC module and blower motor that it controls(as a precaution since that is the device that the ADC drives)After removing the icemaker and all the back panels in the freezer you can access the blower motor. The ADC module is accessible after removing the plastic panels in the top of the fridge. Look for a burn spot on the module. Be sure to order the parts using the fridge model # and not the parts # on the wiring diagram(they will have changed since the model was built). Mine needed an updated wiring harness and deleted one of the dampner motors. Be sure to replace one wire at a time so not to get confused of wire location. Pretty straight forward repair if you have some mechanical ability. I have never repaired a fridge before, but have done car electronic work.

first i by passed the timing board, with a ele cord to the fan motor to keep the fridge cool till your parts got here, which was realy fast delivered,
the fan would come on because the board was fried.
it took abot 30 min to install every thind just be carefully unpluging anything.things will break i guess metal eing cold makes the conne4ctors stick together.
