The damper assembly was already replaced. Just replaced the adc 1 with an adc 4. The new wiring harness only had a purple/white, black, and green wire for the fridge side control. the old harness had an additional pink wire. Is this normal with the adc 4 to not have the pink wire?

My evaparator fan was not working, so I replaced the adc unit with the new orange one, part # 5303918476. Now, the refrigerator part is freezing in all except the top 2 shelves. The ice maker and water dispenser are not working, I suppose the water is frozen up that goes to it. We used the new wiring harness that came with the unit. Where there was only one wire on the new one, we hooked it into the one next to the foam. My refrigerator is Frigidaire model # FRS6R5ESBG. Thanks in advance for your help.

Latest Questions

My freezer/fridge is not working correctly, not cooling. I hear a buzzing sound for about 5-10 seconds every few minutes. The sound is coming from the compressor on the back of the machine. Fan next to compressor is working, I cleaned the condenser coils next to the compressor to be safe. Compressor is hot, not too hot, but not "warm" (not sure what would be warm vs. hot). Not too hot to touch. Plugged the fridge in and turned it on. Left it for a couple hours and checked the evaporator coils and they are frosting up just fine. After a few more hours, right before I went to bed, I heard the click/buzz cycle by the compressor again. Checked for frost on the coils and no frost...Checked again this morning and freezer is not as cold, no frost on coils. So it sounds like the compressor and fan on back bottom is working fine, but unit is not kicking back in after defrost cycle. WOuld this mean a new adaptive defrost control board? I have a new PTC starter and capacitor on order since I thought those could be the culprits at first (and it's cheap). Thanks for any insight.

My evaporator coil is icing up, preventing airflow from the freezer side to the fridge side. I replaced the defrost thermostat but that did not solve the problem. Is the next step replacing the adaptive defrost control board?

The freezer fan cycle on an off one to two seconds continually. Temperature in freezer and refrigerator is okay. Occasionally fan will continue to run for a period of time? What can I do to correct this? Is the adaptive board defroster the problem?
