Question about Frigidaire FRS3R5EMB Side by Side Refrigerator
Pro series 26 ft.
Hello. When you say ADC do you mean automatic defrost control, better known as a defrost timer? If so it can usually be found in the top inside of the fresh food compartment, or behind the bottom kick plate. Also the only thing that will be exposed if it is inside the unit is a small dial smaller than the size of a dime and it can be advanced with a flat head screw driver. If it is behind the kick plate it will be a small white, black or clear object with wires coming out of it. If it is a unit with a digital display you will have to call a service man to come out and take a look at it, has it most likely has what is called an adaptive defrost system that is controlled by the computer.

I believe what is happening is your freezer is not defrosting properly and your auto damper is opening just enough to keep the temperatures safe on the fresh food side. look into freezer and the rear wall. Is frost building up on the rear wall? If ye then this is a defrost issue and you will need to unplug and manually defrost with a hair dryer. Don't be afraid to remove the rear panel in freezer so you can see just what happens when defrost is not taking place. I think it is possible that you have a model LSD2615HEW but you will need to confirm before asking for parts. Inside the fresh food compartment and behind the control panel the model LSD2615HEW for example only has a Click Here=> 12002495 Adaptive Defrost Control Board I say example only because I had to assume your model number. This board is the most likely reason for this problem. Sometimes you may see burn marks on one side of board but not always. Click Here for location=> LSD2615HEW Controls and part 12 in photo is the ADC or 12002495 Adaptive Defrost Control Board The only other cause will; be a defective defrost heater or defrost thermostat. The defrost heater is=> 67004188 Defrost Heater Assembly testing of the defrost heater is also in a short tutorial on this same page. Then finally it is always a good idea to replace the defrost thermostat while inside replacing the defrost heater if need. Part number for the defrost thermostat is=> 67004757 Defrost Thermostat and can be found here=> LSD2615HEW Freezer Components If you have any questions I will be here to answer them for you, If helpful please rate this solution, Thank You, Sea Breeze

The refrigerator/freezer defrost system can be checked by
manually initiating a defrost cycle. There
are two methods of initiating the ADC Test Mode.
First Test Method:
1. Turn the thermostat off for 15 seconds.
2. Turn the thermostat on for 5 seconds.
3. Turn the thermostat off for 15 seconds.
4. Turn the thermostat on for 5 seconds.
5. Turn the thermostat off for 15 seconds.
6. Turn the thermostat on for 5 seconds.
7. Turn the thermostat off.
In 3 to 8 seconds the ADC should turn on the defrost heater (with the bimetal closed). NOTE: The test mode will terminate when the bimetal opens. If the refrigerator/freezer is already in defrost, Test Mode can be terminated by unplugging the refrigerator/freezer from the wall outlet and waiting 30 seconds before plugging it back in. The refrigerator/freezer should immediately go into cooling mode if the thermostat is closed.
If this first test procedure fails to make the ADC initiate a defrost cycle, try the following procedure to make the ADC begin the Test Mode.
Second Test Method:
1. Disconnect the refrigerator/freezer from the wall outlet for at least 30 seconds.
2. Turn the thermostat off.
3. Reconnect power to the refrigerator/freezer.
Within 3 to 8 seconds the ADC should turn on the defrost heater (with the bimetal close). If the unit fails to go into the defrost mode during this test, the problem may not be with the ADC. A defective bimetal may be the cause of the failure. The ADC will only go into a test mode if the bimetal
is closed. If the ADC senses an open bimetal it will return to the cooling mode within 3 to 8 seconds.
HELPFUL HINT: Upon entering the Test Mode, the relay mounted on the ADC board should turn off the compressor and turn on the defrost heater. Listen for the relay to click.
• If the relay clicks one time when entering the Test Mode, check for continuity in the defrost heater.
• If the relay clicks two times, check for an open bimetal.
