Adaptive Defrost Control Board

Dave W. for Model Number FRS23H5ASB8

Answer Hello Dave. Test and see if you are losing power to the fan motor. If not, and the fan starts and stops, you will need to order and replace the fan motor on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Answer Gary, With the redesign of the part they eliminated the wire that would normally go from the thermostat back to the damper motor. This is now routed through the ADC board. You will want to put the black on the left side and green to ground and the other wire to the other outside terminal. Turn on the unit and test it as it may be necessary to move the white/purple to the other terminal.

Answer Seth, Not showing any information as to a change on the control that would cause it to not go into the defrost cycle manually. You do need to make sure that the light bulb is working and hit the light switch 5 times in six seconds. 

Keith for Model Number FRS26R2AWB

Answer Keith, Based on the wiring diagram there is only one switch on the damper assembly. If yours has 2 then it sounds like you hooked up to the wrong switch. Also double check to make sure that you did not connect the freezer and refrigerator thermostat wires incorrectly. 

Kevin H for Model Number GLRS267ZA

Answer Kevin, If the unit is shutting down for long periods of time and the fans not running then yes the unit may be getting stuck in defrost. If the unit is constantly running but not cooling and all the fans are running there may be a defrost issue. With defrost failure there will be heavy frost build up on the rear wall of the middle to lower freezer compartment. If this is the case you would want to check the defrost thermostat and heater first. You would do a continuity test and if no continuity then you would replace that part. If both have continuity the control 5303918476 would be at fault. 

E for Model Number fridgidaire GLRS237ZCW2

Answer E, Make sure that the condenser fan motor is operational but the unit should not start right back up after it shuts down. If it is attempting to restart after 10 to 20 seconds of shut down then there would be a problem with the thermostat calling for compressor to run again.
