Question about Amana ARB2557CW / ARB2557CB / ARB2557CC Bottom Freezer Refrigerator

1 Answer

After cleaning coils and in back of fridge, it appears that the defrost keeps cycling every 5 minutes

Amana ARB2557cc - Yesterday, I cleaned the coils under the fridge. Pulled out the fridge and carefully cleaned rear fan and accessible components. Took out drawers to throughly clean freezer. Took back panel off of the rear of the freezer to make sure fan was free to spin and check for ice. Found ice on thin 'coils' in this area. Used blow dryer on cool setting to melt ice. Put everything back together. Within 10 minutes noticed that humming noise that clicks on and off started to cycle about every 5 minutes. By this morning, the ice was 1/2 thawed; lost ice cream, frozen vegtables are mushy. Fan is running in freezer and it appears to be cool, but not cool enough.

Hi
Step 1:
 If the compressor runs all the time, turn the control knob to the OFF position. If the compressor still runs, unplug the unit, then pull off the control knob and remove the screws holding the thermostat in place. Pull out the thermostat and remove either the red or the blue wire from its terminal. Plug in the unit. If the compressor doesn't run, the thermostat is faulty. Replace it with a new thermostat.

Step 2: 
If the compressor runs after the wire is removed from its terminal, there is probably a short circuit somewhere in the unit's wiring. In this case, don't try to fix the problem yourself; call a professional service person.

Step 3: 
If the refrigerator or freezer runs but the box doesn't cool, unplug the unit and remove the thermostat with a screwdriver. Disconnect both wires from the thermostat. Tape the ends of the wires together with electrical tape, and plug in the appliance. If the refrigerator starts and runs normally, the thermostat is faulty. Replace it with a new one of the same type. Connect the new thermostat the same way the old one was connected.

Step 4: 
If the freezer compartment is normal but the refrigerator box doesn't cool, set the dials that control both compartments to mid-range. Remove these knobs (they're usually friction-fit). Then unscrew the temperature control housing; you'll see an air duct near the control. Replace the knob on the freezer thermostat and turn the control to the OFF position. Open the refrigerator door and look closely at the air duct. If this duct doesn't open wider in about ten minutes, the control is faulty. Replace the control with a new one of the same type. Connect the new control the same way the old one was connected.

I have an amana fridge model # arb190rcw.nothing remains frozen in the freezer.and i have noticed ice on the back wall of the freezer compartment


Your cooling coils have frosted so much that there is ice forming allover the cooling coils and preventing the actual cooling inthe fridge. First of all shut off the fridge for about 10 hours and wait for all the ice to defrost. Clean up your fridge well and then check inside of the freezer compartment for break in wiring, failure of the heater or the thermostat. Now put the fridge on and see if the cooling comes back.If the set works ok then dont worry till you experience the same fault coming back. In this case your auto defrost timer could be faulty as it is not doing the 8 hours cycle defrosting. Check this out test and replace . Get help if you are not familiar. good day

Top refrigerator warm bottom is ice cold.


An automatic defrost time turns the defrost cycle on and off every 24 hours. If problem continues, problem is most likely defective defrost timer.

Even electronically controlled units often have electro-mechanical timers for defrost cycle.

Freezer part of my amana side by side is cold but not freezing


DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.


Part 1541 on this diagram is your timer. It's under the front behind the kick panel. http://www.appliancepartspros.com/partsearch/model.aspx?model_id=21463&diagram_id=646025#d646025

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others. You can post your model number into one of several appliance parts sites on the internet and search for defrost components to find your parts.

Amana arb2557cw condenser coils freezing, fridge not cooling


There are a few things that it could be. Do you mean the evaparator coil? This would be the coil on the inside of the freezer, the condenser is outside the unit. If the evap. coil is freezing, you could have to much in your freezer blocking air flow. You could also have a evap. fan not running. Check the owner's manual for the location of the defrost timer, it could be bad. The thermostat needs to be checked and set so that it is at a reasonable level. One last thing to check would be the condensate drain. Make sure the drain is not plugged or the line is not plugged. Good luck.
