Frigidaire defrost problems

Hi i have a frigidaire model frs23f4cw3 a few months ago i had an internal short in my compressor and it burned my adc board so i replaced after the compressor was fixed under warranty, now my evaporator is freezing up i have been defrosting with a heat gun, i have replaced the thermostat, i have checked resistance of the heater (29 ohms), and i have pushed the button 5 times to get it into defrost mode but my heater never comes on. I am now trying a full defrost for a day or so and i will start it back up again but any bit of knowledge on what else could be wrong would be greatly appreciated. thanks

If the heater and thermostat are good and wired correctly then the only other thing would be the defrost timer board.

Model #FRS26R4CBB


Hi Friend, this is Z. I am happy to assist you!

I show that the defrost timer for the above-listed model number of your Frigidaire refrigerator has a defrost control board (ADC - Automatic Defrost Control). This can be found in front of the damper. I hope this information proves useful.

The refrigerator will not cool. It comes on and shuts off but does not kick in to cool. HELP


Hi,
The two most common problems on this model were either the relay to the compressor or the ADC (adaptive defrost control) both parts can prevent the cooling for the unit. Relay kit or ADC. I would visually inspect the relay to the compressor with the unit unplugged, smell it to see if it smells burnt, if so replace it. If it is ok, then I would suspect the ADC board and it will need to be replaced.
Good Luck

HOW DO YOU PUT REFRIG IN DEFROST MODE WHEN IT HAS ELECTRONIC DEFROST CONTROLLER


You didnt give the make of the ref.; But your solution is here for most all

The newest defrost feature in modern fridges is the electronic adaptive defrost control board. *Maytag has one version, see picture...to put this adaptive defrost style of fridge into defrost, short with a small screwdriver between L1 and test on the adaptive defrost board, wait 3 seconds and you should hear a "click" noise from the relay and the fridge will shut off and go through a defrost cycle. A close up common way *this* version of the Maytag/JennAir control is wired.
Amana also has a version of adaptive defrost, see info sheet for some help on the Amana version. Press refrigerator light switch five times in six seconds to initiate defrost cycle. Pressing five more times within six seconds will cancel defrost and go straight into the run mode. Similar operation on both bottom mount and SxS refrigerators. After the defrost terminator/thermostat opens, six minutes of dwell time occurs before the compressor and condenser fan motor will operate. After defrost terminator/thermostat open, 10 minutes of dwell time occurs before the evaporator fan motor will operate.
Frigidaire has also jumped into the market with an adaptive defrost board. The fresh food section light switch and light bulb must work. To initiate a defrost cycle, open the door and push the light switch in and out 5 times within 6 seconds. The compressor and fans should shut off and the defrost heater should come on. Open the door and push the light switch in and out 5 times within 6 seconds to remove the refrigerator from the defrost mode and back into a cooling mode.
Frigidaire - referance model FSC23F7DSB3
This product comes equipped with an Adaptive Defrost Control (ADC). To activate manual defrost, press and hold the Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. A ?¿½d?¿½ in the freezer temperature window and ?¿½F?¿½ in the refrigerator temperature window will display when the heater is activated. To deactivate manual defrost, press and hold Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. ?¿½d?¿½ and ?¿½F?¿½ will be displayed until the defrost cycle is complete. (approx. 8 minutes)
For some Whirlpool refrigerators - some Kenmore refrigerators are made by Whirlpool ( 106.######## )
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.
?¿½ If the relay clicks one time when entering the Test Mode, check for continuity in the defrost heater.
?¿½ If the relay clicks two times, check for an open bimetal.

Maytag S-S Refrigerator MSD2756GEW forcing defrost cycle
I replaced my defrost heater two weeks ago, but the frost built back up on the evaporator coils. Replaced the adaptive defrost board with new ( Maytag p/n 6100598 8 ) board. Want to force a defrost cycle to see the heater work, so I shorted the L1 pin to adjacent pin (now called DOOR instead of TEST) for three seconds and nothing happens. Compressor keeps running, fans still going etc. Tried pressing the door switches 5 times in 6 seconds and that doesn't work either. Any hints on how to get the defrost cycle to initiate?
Hi,
This might help, a copy:
The issue is that some 12002104 ADC boards have been shipped in the 61005988 ADC board box. Do not reorder the board, the 12002104 board will function the same in place of the 61005988, but you must use the forced defrost method for the 12002104. Jumping "L-1" and "door" will not initiate the forced defrost function.
To Initiate Forced Defrost Cycle:
Cycle cold control on and off three times in six seconds. The cold control needs to be left in the closed (call for cooling) position for the defrost system to energize on all platforms. It is not enough to cycle the cold control knob, the contacts must actually open and close (open doors for a period of time if necessary to force the control to call for cooling). In most cases, you can hear the contacts open and close if they are doing so.
To Terminate Forced Defrost Cycle:
Disconnect power for five seconds.
You were right. I cycled the cooling controls three times and it went into a defrost cycle. Thanks.

You refrigerator was made by Frigidaire Adaptive Defrost Controls Frigidaire Refrigerator Trouble Shooting and Diagnosing
On the initial plugin, or when power is restored to the fridge after a power outage:
If terminating thermostat is open, the fridge enters a compressor (cooling) cycle.
If the terminating thermostat is closed, the first defrost cycle occurs 1 hour
after initial plug-in.
Maximum defrost cycle time is 24 minutes.
Minimum time between defrost cycles is 6 hours. (compressor runtime)
Maximum normal clock time between defrost cycles is 12 hours.
Maximum time between defrost cycles (in "vacation" mode) is 72 hours.
Vacation mode is not entered unless the door has not been opened in at least 24 hours.
Note that the ADC will only enter the defrost mode if the terminating thermostat is closed. If the terminating thermostat is open when defrost is initiated, the ADC board will wait for six minutes and then return to the cooling mode.
ASSUMING that the fridge has been on and running,
and the terminating thermostat is closed,
defrost is initiated by pressing the door (light) switch
at least five times within six seconds.
The defrost heater should start heating up within 8 seconds.
If the above procedure caused the heater to heat up, the ADC board is probably bad; replace it.
If the defrost heater does not heat up, test the defrost heater, terminating thermostat and cold control for continuity as follows:
Unplug the fridge from the wall. Unplug the ADC board from its connector.
Test the connector for continuity between the following leads:
Defrost Heater = DEF TERM (blue) to DEF OUT (brown).
Terminating Thermostat = DEF TERM (blue) to NEUTRAL (lt blue).
Cold Control = COLD CONTROL (orange) to L1 (black).
Replace the defective component.

My frigidaire is not getting cold. Is there a way to troubleshoot to detemine if it's the compressor gone bad?


Good day,
Here is a basic checklist any qualified tech would use to isolate why a refrigerator won't cool.
Items that will cause a refrigerator not to cool.....
1. Defective thermostat
2. Defective freezer fan motor
3. Defective defrost timer or electronic defrost control.
4. Defective defrost thermostat
5. Defective defrost main heater.
6. Defective condenser fan motor
6. Defective compressor overload protector
7. Defective compressor start relay
8. Defective compressor start/run capacitor (some models only)
9. Defective compressor
10. Restriction in refrigeration sealed system
11. Loss of refrigerant (leak)
12. Excessively dirty condenser
13. Broken wires, bad wire harness connectors, ect.
14. Defective fan motor switch (some models only)

As you can see, there are multiple reasons a refrigerator won't cool, or cool properly.
To zero in on the compressor might take you away from the true non-cooling reason.

However. The compressor might have a defective relay or thermal overload that would prevent it from starting or running. Theses items can be removed from the compressor and taken to any appliance parts houses. Most all would be glad to test them for you.
As well, the compressor could have a bad valve internally that would prevent the compressor from pumping refrigerant, or there could be a restriction in the refrigeration lines preventing the refrigerant from circulating properly, or the windings in the compressor could be burned out or shorted, or lastly, the system could have developed a leak. All of the above compressor related issues, except for the first one could only be checked by a qualified tech.
I would treat the problem as a whole with the compressor being one of the potential issues.

Not to throw a monkey wrench into this but a refrigerator is like a car.
9 out of 10 times the problem and solution are obvious. It's that last 10% that take all the training and experience.

My kenmore 10658026800 does not cool... where is the defrost timer?


I found the parts page but Kenmore does not have the parts listed. You refrigerator was made by Whirlpool and Sears changed the model number. Looking a the sears photos your model does not have a defrost timer but does have an Adaptive Defrost Control located inside the fresh food compartment and behind the control panel where you set temperatures. Defrost failures and compressors stopping as you said in your post are common for the ADC I will continue to try to cross it over to the Whirlpool Model but most likely that is the problem. When an ADC fails strange things begin to happen. Once you start to look for the ADC unplug and remove the top shelf to help lower the control panel. I will return soon to leave you more contact information and what the part looks like. OK your model came with three different styles of defrost controls located in same area. Timer and two different ADC boards. I will need you to look and read the numbers off of what you find. If a timer we can test, defrost boards usually have burn marks on front or back when damaged. Let me know what you find and we go to next step. Is ice building in freezer rear wall or is just lights on? Sea Breeze

I do see the power to the evaporator fan section going through the adaptive defrost part number 240554502 It would not hurt to unplug for a few moments and open the control panel inside the fresh food section and examine that control board. With it doing that you may see signs of heat or burn marks on the ADC Let me know, Sea Breeze
