Amana SCD22JL Replacing the Defrost Thermostat fixed the fan problem. However I am getting very little air flow into the refrigerator side. The Defrost is working, the evaporator fan is running, the evaporator coils are not iced up, and the damper that controls the air flow on the refrigerator side is fully open. Any Thoughts?

One of two things has happened. Either your evaporator fan has stopped working and not forcing the cold air down the cooling tubes to cool the refrigerator or the cooling tubes have iced up and the cold can't get to the refrigerator side of your unit - which is generally a defrost circuit malfunction.

If you don't feel air flow in the refrigerator section, then I am on the money. First check the fan and see if it is turning, if not replace. If it is turning, then you will need to use a hair dryer to defrost the dreezer and air tubes. Then troubleshoot the defrost circuit which is normally made up of a defrost heater, defrost thermostat and defrost timer.

Hi,
Could you again give us the model and manufacturer for the refridgerator.

Thanks

The problem is usually air flow across the evaporator coils (the coils in the back of the freezer section) All of the cooling in the refrigerator section is done by the circulated air across these coils..........If the coils are frosted solid you have a defrost problem....(you can manually defrost which will last about 3 weeks before it is frosted up again) Normally it automatically defrost about every 8 hours for arould 20 minutes..... If the fan above the evaporator is not running it may be a bad fan motor or the defrost bimetal in series with it is open and needs replacing.........Lastly if you hear the fan running and feel air coming out of the damper, check the air return to the freezer section(usually not the problem, usually it is the bimetal thermostat.......This is kind of general info for a bottom mount or top mount or side by side unit......hope it helps

lack of air flow from freezer to the refrigerator, since you have a side by side, this narrows it down a little. it could be not automatically defrosting, visual sign is thick frost on back wall of freezer, due to either a bad: main control board; defrost heater; evaporator thermistor; or safety bimetal thermostat. could also be a bad evaporator fan motor, due to a bad motor; bad main control board, or both. air damper is stuck closed, preventing air from entering fresh food side. or ice build up due to an improper door seal or other warm air source.

Quick temporary fix - defrost the freezer (inside frezer lower back) it is probably full of frost/ice - this prevents air flow and therefore no air enters fridge side. common failure due to bimetal defrost thermostat failure ($20) - replace this part for a permanent fix - also advisable to swap out the defrost timer at same time

if the freezer is getting cold the problem is due to the cold air from the freezer not getting into the refrigerator. There are several things that can cause this problem. The coils in the freezer icing up and not defrosting properly is one of the things that can cause the refrigerator not to get cold enough. Another problem is the fan that blows the cold air from the freezer compartment into the refrigerator, not working. When the compressor is running open the refrigerator's door and push the switch that makes the light go out. You should hear the fan blowing the cold air from the freezer into the refrigerator, when this switch is pushed in. If the fan is working then you will need to find what is blocking the air flow. Iced up coils are a common problem. The icing problem can be due to a defective defrost timer or something defective in the defrost circuit. Click here for more information.

REFRIGERATOR TROUBLESHOOTING
#1 Refrigerator side getting warm Freezer still cold
Evaporator fan motor not running.
Defective defrost timer. See Defrost Diagnosis Procedure
Defrost heater defective. See Defrost Diagnosis Procedure
Defrost thermostat defective. See Defrost Diagnosis Procedure
Airflow blocked from freezer compartment.
Freezer control turned to "coldest" setting blocking air flow to refrigerator side. On most refrigerator/freezers, the freezer control closes a baffle when turned to coldest setting, and this blocks off the air flow to the fresh food compartment.
Fan blade broken.
Defective door switch on older models.
Light staying on with door closed.
2 Refrigerator & freezer compartments both are getting warm
Make sure refrigerator is plugged in and has power.
Condenser fan motor on bottom under refrigerator not running.
Condenser coil clogged.
Defective defrost timer. See Defrost Diagnosis Procedure
Defective defrost heater. See Defrost Diagnosis Procedure
Defective defrost thermostat. See Defrost Diagnosis Procedure
Evaporator fan motor not running.
Cold control defective.
Compressor overload defective.
Compressor relay defective.
Light staying on with door closed.
Compressor defective.
Low on refrigerant. #3 Freezer compartment getting hot.
Defrost timer stuck in defrost cycle.(replace)
Defrost thermostat stuck.(replace)
Ice maker stuck in harvest cycle
Light staying on with door closed. 4 Ice maker not making ice
Defective inlet water valve.
Freezer temperature not cold enough. (see problem # 2 & 3 above)
Defective thermostat in ice maker.
Defective drive motor.
Water inlet tube clogged with ice.
Defective module in newer style icemaker. 5 Refrigerator sweating around door edges
Door gaskets leaking air.
Defective case heaters.
Energy saver switch not set to reduce exterior moisture

its quite possible, that "the box with thermostat and small door fix on chanel for regulating cold air from freezer in fridge side", is not the problem, there can be a few diff problems, the fan in the freezer may n ot be blowing the air over, you may have a bad defrost thermostat, preventing proper defrost cycles and building up with ice preventing proper air flow. i would look into a little more before condemning the part your lookin at( damper control)

NEWER T-49 s DO NOT HAVE ANY DEFROST HEATER OR TIMER OR CUTOFF'S All solutions involving repairs on these items are bogus. The defrost occurs when the compressor shuts down normally. During this time,since the fan never stops, it should circulate above freezing air around the coils and a slow defrost may occur. It is a poor system at best, and does not work well if the compressor runs a lot. MY erratic cooling was fixed by removing the copper sleeve and cold control probe from the evaporator(cold coil on top) Polish up the copper tube and the probe, reinsert and bend the copper sleeve very slightly so that it fits snuggly into the evaporator. Mine was very loose and not making good contact with the metal evaporator, giving erratic control of temperature.. Good Luck!!

#1. DEFROST TIMER stuck or defective. Not allowing DEFROST CYCLE to occur. Most probable.
#2. THERMOSTAT (cold control) has gone bad.
#3. CIRCULATING FAN. It pulls air from the FREEZER side into the REFRIGERATED side.
#4. and lowest in probability. LOW (leaking) coolant charge.

PLEASE DISREGUARD GUEST FIXYA SOLUTION,FREEZER PROBLEM PROCEDURE IF NOT DEGITAL,FIRST CHECK IF ICE ON BACK FREEZER WALL. STEPS-FIND DEFROST TIMER,BOTTOM FRONT ,BOTTOM BACK, INSIDE FRIG.ON CONSOLE,LISTEN TO SEE IF FAN IS RUNNING IF SO TURN THE DEFROST TIMER CLOCKWISE TILL YOU HEAR A CLICK SEE IF FAN TURNED OFF IF SO YOUR FREEZER IS IN DEFROST,FREEZER WILL COME OUT OF DEFROST IN 20-30 MINUTES IF IT DOES AND THE FAN COMES ON YOU HAVE ELIMINATED DEFROST TIMER&FAN,NEXT REMOVE BACK PANEL TO FREEZER IF THERE IS ICE FORMING REMOVE BOTH LEADS TO HEAT AND CHECK WITH VOLT METER ON OMES,IF YOU GET ANY READING THE HEATER IS GOOD,IF NO READING REPLACE HEATER AND CLIPON TEMINATOR,IF HEATER IS GOOD DEFROST COILS WITH HAIR DRYER TOP TO BOTTOM AND THIS WILL ALSO CLEAR THE DRAIN,IF EVERYTHING CHECK OUT GOOD DEFROST TIMER ,FAN ,HEATER, DRAIN, YOU NEED ONLY TO REPLACE THE LITTLE ROUND CLIP ON TERMANATOR,LET ME KNOW-MIKE
